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. 相似文献
