Veterinary Psychopharmacology.

The stress response affects the central nervous system and multiple other systems in the body. Chronic mental and behavioral pathologies are associated with inflammation, dysfunctions in the immune response and an increased risk for other chronic inflammatory and metabolic diseases. Psychiatric treatments alleviate fear, stress and anxiety, increase the qualify of life and lifespan for dogs and cats. Multiple safe psychoactive medications that can be used in association are available to help veterinary patients. Clinicians should understand the function of neurotransmitters and hormones on emotional processing, cognition and behavior, and drug mechanism of action so medication selection is appropriate for each individual patient.

Feeding Cats for Optimal Mental and Behavioral Well-Being.

In this article, we review cats' feeding behaviors, and discuss ways of feeding cats that promote physical and mental/behavioral health, while providing cats with choices that allow expression of preferences. We address the management of several feeding issues that cat owners may face, such as obesity, pickiness, begging for food, and feeding in multi-cat households. Food puzzles are one way to provide environmental enrichment for cats, and food can be used in multiple ways for behavior modification in the clinical setting, including counterconditioning and differential reinforcement of alternative behaviors.

Agonistic behavior and environmental enrichment of cats communally housed in a shelter.

OBJECTIVE: To evaluate the presence of a dominance rank in a group of cats and the relation between agonistic behavior and the use of resources, including environmental enrichment, in these cats. DESIGN: Observational analytic study. ANIMALS: 27 neutered cats in a shelter in Sao Paulo, Brazil. PROCEDURES: The cats were video recorded for 4 consecutive days to obtain baseline data. Subsequently, a puzzle feeder was added as an enrichment device every other day over 8 days, for a total of 4 days with enrichment. Cats were also video recorded on these days. All pretreatment and posttreatment agonistic behaviors and interactions with the puzzle feeder were recorded by reviewing the videotapes. RESULTS: 143 agonistic encounters were recorded, of which 44 were related to resources and 99 were not. There were insufficient agonistic interactions to determine a dominance rank. Presence or absence of the puzzle feeder did not affect the rate of aggression. There was no significant effect of weight, sex, or coat color on the rate of aggression, and aggressive behavior did not correlate with time spent with the puzzle feeder. Twenty-three of the 27 cats interacted with the puzzle feeder. CONCLUSIONS AND CLINICAL RELEVANCE: In a stable group of communally housed cats, environmental enrichment did not cause increased aggression as a result of competition for the source of enrichment. Because environmental enrichment increases the opportunity to perform exploratory behaviors, it may improve the welfare of groups of cats maintained long-term in shelters, sanctuaries, or multicat households.
