Adaptation of domestic cats to confinement

Although most cat owners believe that cats have a need to roam outdoors and that this activity benefits their welfare, roaming also carries welfare risks for the cat. On the other hand, most cats have not been selectively bred to be “house cats” that live indoors 24 hours a day. Until recently, most domestic cats were allowed to roam freely, and they contributed to the large population of stray and feral cats. In turn many pet cats come from the stray and shelter population. A large proportion of domestic cats have not been selected for easy adaptation to live in confinement and in close contact with people, and socialization to people may also not have been complete in these cats. However, cats are adaptable to a wide range of environments and are generally not known to show clear behavioral signs of problems, such as stereotypic behavior. Problem behaviors of cats are often not abnormal behaviors per se but natural behaviors that need to be redirected to appropriate substrates. The most frequent behavior problems cited by cat owners are: inappropriate elimination, scratching, aggression, anxiety, eating problems, vocalizations, and excessive activity. Despite the frequent reporting of these behaviors, most cats will generally adapt to indoor housing provided there is sufficient space and that they are accustomed to these conditions from an early age. The Five Freedoms, developed to assess the welfare of farm animals in intensive systems, can be modified to assess the welfare of cats housed in confinement. Specific features of the environment that can enhance the welfare of cats in confinement are discussed.     

Attitudes of owners regarding tendonectomy and onychectomy in cats

OBJECTIVE: To compare the incidence of behavior problems following tendonectomy or onychectomy in cats, as well as attitudes of owners following these procedures. DESIGN: Nonrandomized clinical trial. ANIMALS: 18 cats that underwent tendonectomy and 39 cats that underwent onychectomy. PROCEDURE: Owners of cats that underwent tendonectomy or onychectomy between February 1993 and May 1998 were contacted by telephone and asked several questions regarding reasons for surgery as well as complications and behavioral changes in cats following surgery. RESULTS: The most common reason for considering tendonectomy or onychectomy was to avoid damage caused by the cat scratching household materials. Avoidance of injury to humans or animals was chosen more often by owners whose cats underwent onychectomy than those that underwent tendonectomy. Tendonectomy was more likely to have been recommended by veterinarians than onychectomy. Significantly more cats that underwent tendonectomy (67%) than onychectomy (44%) returned to normal activity within 3 days after surgery. Significant differences were not detected regarding behavior problems after surgery. CONCLUSIONS AND CLINICAL RELEVANCE: Although tendonectomy and onychectomy involved some medical complications and behavior changes following surgery, owners had positive attitudes regarding both surgeries after the immediate postoperative period. Tendonectomy may be a humane alternative to onychectomy, although owners need to be advised that nail trimming is still necessary in cats after surgery.     

Onychectomy and its alternatives in the feline patient

Onychectomy and its alternatives are often sought by owners to provide permanent alleviation of scratching behaviors in cats. These alternatives include behavioral modification, nail caps, and deep digital flexor tendonectomy. Although surgical options are commonly performed, they are controversial and have potential complications. Our role as veterinarians is to educate clients to allow them to make the best decision for themselves and their pets. The purpose of this article is to provide an objective review of the positive and negative aspects of onychectomy, describe and discuss alternatives to onychectomy, and review the specific surgical techniques.     

Psychotropic drugs and behavioral therapy

Psychotropic drugs often are helpful in the treatment of selected behavior problems in dogs and cats. Drug therapy is rarely curative by itself and in most cases is only indicated as ancillary therapy in a behavior modification program. Very few of the psychoactive drugs are approved for use in companion animals, and owners should be made aware that their use is considered experimental. Before prescribing any of the psychotropic drugs, veterinarians should be thoroughly familiar with dosages, side effects, and contraindications. Some of the more common behavior problems in which drug therapy may be useful are reviewed.     

Animal behavior and animal welfare

The value of behavioral techniques in assessing animal welfare, and in particular assessing the psychological well being of animals, is reviewed. Using cats and horses as examples, 3 behavioral methods are presented: (1) comparison of behavior patterns and time budgets; (2) choice tests; and (3) operant conditioning. The behaviors of intact and declawed cats were compared in order to determine if declawing led to behavioral problems or to a change in personality. Apparently it did not. The behavior of free ranging horses was compared with that of stabled horses. Using two-choice preference tests, the preference of horses for visual contact with other horses and the preference for bedding were determined. Horses show no significant preference for locations from which they can make visual contact with other horses, but they do prefer bedding, especially when lying down. Horses will perform an operant response in order to obtain light in a darkened barn or heat in an outside shed. These same techniques can be used to answer a variety of questions about an animal's motivation for a particular attribute of its environment.     

Parrot psychology and behavior problems.

Behavior modification training, like veterinary medicine, is an exacting science, requiring a knowledge of not only wild avian behavior, but of child and adult human behavior as well. It is important to note that absolutely any changes in a bird's or its owner's environment may trigger a vast assortment undesirable behaviors. Some behavior problems are simple, but most have multiple causes and each of those causes must be determined and corrected before a high rate of success is evident. As in veterinary medicine, some birds respond to general "shotgun" techniques; however, parrots are intelligent and complex creatures. They consider themselves an integral part of their human "flock" and respond as such. Most commonly seen negative behaviors can be altered, at least to some extent, and, in most cases, they can be alleviated completely. Yelling at the bird, striking it, or any other type of confrontational behavior modification technique is virtually useless and can actually worsen most situations. A high percentage of success involves extensive history taking, an understanding of human and wild animal flock behavior, and the time to create a complete program for each individual and its owner.     

An owner survey of toys,activities, and behavior problems in indoor cats

The objective of this study was to survey the owners regarding the frequency and duration of their daily interactions with their indoor cats, the provision of toys and activities by the cat owners, and the prevalence of 6 selected behavior problems (aggression to owner, aggression to visitors, periuria, inappropriate defecation, inter-household cat aggression, and intercat aggression to outdoor cats). The sample population was 277 clients from 5 veterinary practices who presented their domestic cat for anything except a behavior problem. The average number of toys and activities reported by owners per cat was 7, and the most common toys/activities used by owners in this survey were furry mice (64%), catnip toys (62%), and balls with bells (62%). A total of 78% of the owners reported that they leave the cat's toy(s) available all the time. All owners reported playing with their cat, whereas most owners (64%) played with their cat more than 2 times per day and reported play bout durations of 5 (33%) or 10 minutes (25%). Owners who reported play bout time of 5 minutes or more reported fewer behavioral problems than those with play bouts of 1 minute (P < 0.05). A total of 61% of the owners reported that their cat engaged in 1 or more of the 6 selected behavior problem(s), but only 54% of the owners who reported behavior problems in their cats reported that they had talked to their veterinarian about the problem. The 2 most frequently reported behavior problems were aggression to the owners (36%) and periuria (24%). Female cats were 50% less likely to be reported to have 1 or more behavior problems than males despite an equal sex distribution in the survey population (P < 0.05). The relationship between individual behavior problems and individual toys and activities was evaluated by use of a logistic stepwise regression. These findings are discussed as they relate to the understanding of behavioral needs of indoor-housed cats and the potential role of environmental enrichment in the home setting.     

Nonhealing subcutaneous wounds in the cat and proposed surgical management techniques

Nonhealing wounds in cats are a source of frustration for veterinarians and pet owners alike. These wounds are known for their insidious onset and tendency to recur after standard surgical closure. The presence of a feline wound that fails to heal in the face of appropriate therapy should initiate an extensive diagnostic evaluation for an etiologic agent. Initially animals should be screened for causes of immunosuppression or systemic disease. The local wound environment should then be evaluated through a combination of wound exploration, cytology, histopathology and tissue culture for evidence of a foreign body, neoplasia, or other less common etiologies of these wounds. Many of the less common etiologic agents require specific tissue handling for successful microscopic identification and culture. It is therefore essential for veterinarians to be familiar with the various causes of nonhealing wounds in cats so that laboratories can be alerted of the need for specific diagnostic techniques. Recent surgical and medical advances have the potential to facilitate the successful treatment of these wounds. With improved veterinary awareness of the potential etiologies of nonhealing wounds in cats and improved medical and surgical management techniques many wounds can now successfully be treated.     

Potbellied pig husbandry and nutrition.

Vietnamese potbellied pigs, when appropriately cared for, make excellent pets for some people. However, their proper housing, care, and training is more challenging to the average person than that required for most traditional pets, such as dogs and cats. Failure to feed and house the pet pig appropriately results in the most common health and behavior problems. The obese, intractable pet pig gives little pleasure to a pet owner and appears to lead a very poor-quality life, frequently leading to the pet pig being given away or worse. Preventing health and behavior problems is easy if pet owners are armed with correct information early, either before or immediately after their acquisition of a pet pig. A veterinarian prepared to share this information can save the lives of many pigs as well as keep clients happy and coming back.     

Undesired behaviour in horses: A review of their development,prevention, management and association with welfare

Undesired behaviours are a common problem amongst leisure and sporting horses in the UK and have a significant impact on the work of equine practitioners. In most cases, behaviours considered aberrant by owners are normal responses for their horses. Behaviours perceived as ‘naughtiness’ may in fact signify direct actions to avoid pain‐ or fear‐inducing stimuli. Examples that practitioners might deal with include trailer loading problems, avoidance of having saddlery equipment applied or reluctance to leave the yard. Even where no evidence of physical problems or pain can be detected, avoidance behaviours may reflect learnt responses that previously led to success in evading unpleasant consequences. Because owners often misunderstand the reason for such behaviours to develop in their horses, attempts at resolution often involve suppression or punishment based approaches. Although repeated subjugation of undesirable responses may ultimately appear to resolve the overt behavioural problem in some cases, in many others it can lead to a worsening of the problem, the development of alternative avoidance strategies or the horse learning that escaping the source of its pain or anxiety is impossible and ceasing to respond. Some horses develop abnormal or repetitive behaviours, which are not in the ‘normal’ behavioural repertoire. These stereotypic behaviours, sometimes termed ‘vices’, can indicate strategies to cope with a suboptimal environment. Indeed, their performance may serve to improve the situation for the animal. Attempts to suppress or prevent horses showing stereotypies, therefore, will generally exacerbate the underlying welfare problem. When dealing with either stereotypies or avoidance behaviours, it is important to recognise the role of learning in their development and maintenance. Resolution involves both understanding the underlying motivation for showing the behaviour and how it has become reinforced and established over time, for each individual case. The use of environmental change and/or behavioural modification techniques that are both successful and welfare compatible, are important in dealing with undesired behaviour in horses and selection of suitable professionals for referral an important responsibility for the equine practitioner.     

Canine and feline nasal neoplasia

Dogs and cats of our society have outgrown their status as merely pets and are now considered our close companions and even family members. This shift in their roles has led to pet owners seeking improved preventative medicine for their four-legged friends. Subsequently, dogs and cats are living longer lives than ever before and developing more old-age-related diseases. One of the most devastating diseases of older animals is cancer. Once a veterinarian has detected cancer in a pet, pet owners seek advice on their next course of action. This article is intended to provide concise information regarding the diagnosis and treatment of intranasal tumors of the dog and cat. This article outlines the forms of nasal tumors that are the most common, the recommended imaging and biopsy techniques to diagnose the tumor, and the most appropriate treatments of them.     

Clinical features and outcome in dogs and cats with obsessive-compulsive disorder: 126 cases (1989-2000)

OBJECTIVE: To determine clinical features and outcome in dogs and cats with obsessive-compulsive disorder (OCD). DESIGN: Retrospective study. ANIMALS: 103 dogs and 23 cats. PROCEDURES: Records of patients with OCD were analyzed for clinical features, medication used, extent of behavior modification, and outcome. RESULTS: Most dogs affected with OCD had been obtained from breeders. Male dogs significantly outnumbered females (2:1). Female cats outnumbered male cats by 2:1 in a small sample. Most affected dogs lived in households with 2 or more humans and other dogs or cats, and had some formal training. Client compliance with behavior modification was high. A combination of behavior modification and medication resulted in a large decrease in intensity and frequency of OCD in most animals. Clomipramine was significantly more efficacious for treatment in dogs than was amitriptyline. Only 1 dog and 1 cat were euthanatized because of OCD during the study. CONCLUSIONS AND CLINICAL RELEVANCE: OCD in dogs does not appear to be associated with lack of training, lack of household stimulation, or social confinement. In cats, OCD may be associated with environmental and social stress. Obsessive-compulsive disorder appears at the time of social maturity and may have sporadic and heritable forms. With appropriate treatment (consistent behavior modification and treatment with clomipramine), frequency and intensity of clinical signs in most dogs and cats may decrease by > 50%. Success appears to depend on client understanding and compliance and the reasonable expectation that OCD cannot be cured, but can be well controlled.     

Comparison of interpretation of cat's behavioral needs between veterinarians,veterinary nurses,and cat owners

Cats have certain strongly motivated behaviors, which could be defined as “needs,” that should be understood to provide the cat the best quality of life and assure proper welfare. It is well recognized that cats have several behavioral needs, which if not met, can result in anxiety and secondary behavior problems. These problems can lead to relinquishment or euthanasia. Veterinarians and veterinary nurses have a special role when educating owners. To increase owners' compliance, veterinary professionals should have evidence-based knowledge for the right information to be communicated to feline owners. The goal of the present study was to identify and compare the level of knowledge that veterinarians, veterinary nurses, and pet owners have about cat behavior and to compare their perceptions on this subject. We were also interested in determining whether living with a cat affected the professionals' knowledge base and what they are able to properly communicate to pet owners. It was expected that the veterinarians would have the highest level of knowledge regarding the interpretation of feline behavioral needs. We also hypothesized that those professionals who had or have previously owned a cat would have a better understanding of what cats actually need. A questionnaire, called “questionnaire to assess cat's needs” (QACN), was completed by cat owners, veterinarians, and veterinary nurses. The QACN had 13 different statements about the behavioral needs of cats, and each participant had to select their level of agreement with the statement. The QACN was then scored and a principal component analysis was used to identify meaningful associations. The following 3 components were extracted: elimination, stress releasers, and human stimulation. Contrary to what was expected, the results showed that in some specific areas (stress releasers and human stimulation) veterinarians' and veterinary nurses' knowledge was not significantly different from that of cat owners. This could mean that the role of these professionals in preventing behavioral problems can be very compromised. Those professionals who had owned a cat personally were better at identifying the behavioral needs of cats, with some significant differences (related with stress releasers), compared with those professionals who had never owned a cat. More education about feline behavior should be included when training veterinarians and veterinary nurses for clients to continue to trust these professionals to provide them with evidence-based knowledge about cat behavior.     

The strengths of statistical techniques in identifying patterns underlying apparently random behavioral problems in horses

The inability of owners to recognize patterns behind the seemingly disparate or random behavior problems expressed by their horse has major welfare implications. Principal components analysis has been successfully used to explore relationships between individual behavior problems in dogs, and it may be a valuable tool in recognizing relationships between problem behaviors in horses. Here, we report how principal components analysis has been used to identify relationships underlying individual behavior problems in horses using data generated from a large-scale Internet survey of United Kingdom leisure horses. Horse-level data on the performance of 44 individual behavior problems, encompassing stable-related and handling behavior problems, prefeeding behavior problems, and ridden behavior problems, were reduced to 12 behavior problem components. Each component was composed of groups of behavior problems that may share a common underlying etiology. These findings demonstrate the value of statistical techniques in identifying associations between apparently random behavior problems. Recognizing relationships between individual problems may prompt owners to take earlier action to resolve them, thereby improving their horse’s welfare.     

Handling behavior problems in the practice setting

The veterinary clinic plays a critical role in the prevention and treatment of behavior problems. If behavior problems do begin to emerge, the veterinary clinic can help determine who can advise and guide the owners most practically to improve or resolve the problem. This help might involve the veterinarian, a behavioral technician, a trained staff member, an appropriate trainer, or some combination of these persons. This article reviews how these professional roles might be integrated, depending on the complexity of the problem.     

Experimental evaluation of attachment behaviors in owned cats

Attachment, a normal behavior among social animals, is quite significant since owners worry about their pets and take care of them because of this affective connection. There are not enough research studies that focus on attachment between owners and their cats. The general objective of this study was to identify attachment behaviors, directed toward their owners, in cats of different body types, age groups, and sexes in an experimental situation.Twenty-eight cats, ranging from 1 to 7 years of age and having different body types, were used in the study without taking into account sex or reproductive status. These cats underwent an Ainsworth’s Adapted Strange Situation Test. Event frequencies and behavioral state durations in individual type behaviors such as exploration/locomotion, alertness, and inactivity were registered using direct focal sampling. For data analysis, cats were divided by body type, sex, and reproductive status. Analysis of variance (ANOVA) of locomotion/exploration revealed a statistically significant difference (N = 28, F = 13.55, P < 0.001) between the episodes with the owner, alone, and with a stranger with cats spending more time engaged in locomotion/exploration while accompanied by their owner. On the alert behavior event frequency, difference (ANOVA, F = 7.44, P < 0.05) was found, which showed a higher frequency while in the company of a stranger. Last, in the inactivity time ratio, a significant difference was found (ANOVA, F = 18.55, P < 0.001), where the time spent on this behavior was considerably higher when the animal was alone.These results are consistent with the ones obtained by Ainsworth in children attached to their mothers; therefore, it can be said that cats can manifest attachment behaviors toward their owners. Further studies are indicated to see whether cats can develop separation anxiety.     

Evaluation of cat and owner characteristics and their relationships to outdoor access of owned cats

OBJECTIVE: To examine characteristics of cats and their owners with regard to outdoor access of owned cats. DESIGN: Cross-sectional study. ANIMALS: 184 owned cats admitted to a veterinary referral center for nonemergency health concerns. RESULTS: Cats acquired recently were less likely to be allowed outdoors than those acquired during previous years. Outdoor access was often limited during the day; few owners allowed their cats to remain outdoors at night. Cats acquired from shelters were more likely to be kept exclusively as indoor pets than those cats acquired as strays. The presence of dogs but not other cats in the household was associated with increased outdoor access. Age, health status, and onychectomy status were not significantly associated with outdoor access. Cats allowed outdoor access were more likely to have been bitten by other cats. CONCLUSIONS AND CLINICAL RELEVANCE: The basis for an owner's decision to allow outdoor access appears to be multifactorial, and there may be regional differences in outdoor access of owned cats. Acquisition source is associated with outdoor access of owned cats. Availability of information regarding outdoor access of cats may influence decision making. Educational efforts targeted at specific groups of cat owners, as well as programs that acknowledge owner beliefs regarding quality of life for their cats, may help to address the health, safety, and population concerns associated with outdoor access of owned cats.     

Influence of claw clipping, stocking density and feeding space on the incidence of scabby hips in broilers

1. The aetiology of scabby hips was studied in broilers by scratching the skin with chicken claws, clipping the birds' claws and varying the effects of stocking density and food trough allocation. 2. Gentle scratching twice a week resulted in skin lesions that could not be distinguished from clinical scabby hips at slaughter. Interaction between birds appeared to be a prerequisite for the skin condition to develop. 3. Clipping of the claws at day 25 could almost completely prevent scabby hips at day 45 when the birds were slaughtered. 4. No positive correlation was found between feather condition and the severity of scabby hips at slaughter at day 45. 5. Decrease in stocking density and an increase in feeding space resulted in a reduction of skin lesions at day 25 and resultant scabby hips after slaughter.     

Preliminary analysis of post-adoption outcomes for kittens and adult cats rehomed through a New Zealand animal shelter

ABSTRACT

Aims: To determine the frequency of different types of health and behavioural problems observed in the first month after adoption in kittens and adult cats rehomed through an animal shelter in New Zealand, to assess satisfaction of adopters and to determine the preferences of adopters for provision of post-adoption support.

Methods: The adopters of kittens and cats from an animal shelter in Auckland, New Zealand between 15 October 2016–4 December 2016 were invited to complete a survey 1 week and 1 month after adoption. Respondents were asked about how well the animal was settling into the household, whether they had observed any health or behavioural problems, and what their preferences were for receiving post-adoption support.

Results: Data from at least one survey were available for 83/115 (72.2%) kittens and 70/155 (45.6%) adult cats, with 39/115 (34%) adopters of kittens and 35/155 (23%) adopters of adult cats completing surveys at both 1 week and 1 month after adoption. By 1 month after adoption 57/60 (95%) adopted kittens and 40/53 (75%) adopted adult cats had settled well into their new home. At 1 month after adoption 28/60 (47%) kittens and 26/53 (49%) cats had ≥1 reported behavioural problem, and 16/60 (27%) kittens and 18/53 (34%) cats had ≥1 reported health problem. The most common problem behaviours for kittens were episodes of hyperactivity and scratching household items, and for adult cats were spending most of the time hiding and scratching household items. The most common health problems for kittens were eye problems and sneezing or a runny nose, and for adult cats were sneezing or a runny nose. Amongst respondents, the most helpful support for recent adopters was considered to be an email or phone call 1 month after adoption from the animal shelter.

Conclusions and clinical relevance: Although many adopters reported health and/or behavioural issues in their adopted kittens and adult cats, most issues were generally mild and the adopters were generally satisfied with their animals. Providing new adopters with advice about managing common health and behavioural issues such as upper respiratory disease and scratching household items may increase satisfaction with adoptions.     

Measurement of capillary blood glucose concentrations by pet owners: a new tool in the management of diabetes mellitus

Recently a new method for capillary blood sampling from the ears of dogs and cats was described, which allows the measurement of glucose concentration by means of portable glucose meters. The authors of this report evaluated the suitability of this method for use by pet owners and the potential technical problems. The owners of seven healthy dogs and seven healthy cats were asked to perform two glucose curves (measuring blood glucose concentration every 2 hours for a total of 12 hours). All dog owners and three cat owners were able to perform a reliable blood glucose curve. The most frequently encountered problems were inadequate formation of a blood drop due to excessive digital pressure on the pinna, repeatedly depressing the plunger of the lancet device instead of allowing the negative pressure to slowly build up, and failure to fill the test strip up to the mark. The authors conclude that these steps of the procedure need to be stressed during technique demonstration and that home monitoring of blood glucose concentrations may serve as a new tool in the management of diabetic dogs and cats.
