OBJECTIVE To determine the effects of oral gabapentin administration prior to veterinary examination on signs of stress in cats. DESIGN Randomized, blinded, crossover clinical trial. ANIMALS 20 healthy pet cats with a history of fractious behavior or signs of stress during veterinary examination. PROCEDURES Cats were scheduled for 2 veterinary visits 1 week apart and randomly assigned to receive a capsule containing 100 mg of gabapentin (13.0 to 29.4 mg/kg [5.9 to 13.4 mg/lb]) or placebo (lactose powder) prior to the first visit and the opposite treatment prior to the second visit. Owners were instructed to administer the assigned capsule orally 90 minutes prior to placing the cat into a carrier and transporting it to the veterinary hospital. Standardized physical examinations and blood pressure readings were performed. Owners assigned a cat stress score during transportation and examination, and the veterinarian assigned a compliance score at the visit. Scores were compared between treatments, controlling for various factors. RESULTS Owner-assessed cat stress scores during transportation and veterinary examination and veterinarian-assessed compliance scores were significantly lower when cats received gabapentin than when they received the placebo. Sedation was a common effect of gabapentin administration, and ataxia, hypersalivation, and vomiting were also reported. All effects resolved within 8 hours after gabapentin administration. CONCLUSIONS AND CLINICAL RELEVANCE Owners' perception of stress in their cats is a primary reason for failing to seek veterinary care. Results of this study suggested that gabapentin is a safe and effective treatment for cats to help reduce stress and aggression and increase compliance for transportation and veterinary examination.

Results suggest that male cats and cats from multicat households are more likely to exhibit urine marking behavior than females and cats from single-cat households. Results also suggest that attention to environmental and litter box hygiene can reduce marking frequency in cats, regardless of sex or household status of the cats, and may come close to resolving the marking problem in some cats.

Problematic behaviors are a significant reason for relinquishment, and relinquished dogs are more likely to have problem behaviors. This study utilized standardized surveys of owners (companion animal guardians) relinquishing their dogs to shelters and dog owners visiting vaccination clinics. "Relinquishing" and "continuing" owners were asked questions in the following categories: demographic information, training methods and tools, frequencies in which their dogs engaged in problematic behaviors, and attachment to their dogs. "Relinquishers" were also asked to provide their reasons for relinquishment. The results of 129 surveys (80 relinquishing and 49 continuing) showed that relinquishers scored lower on companion animal attachment than continuing owners. Pit bull-type dogs were represented more in the relinquishing group. Relinquished dogs were no less likely to have attended training classes than continuing dogs. In both groups, owners who used punishment-based collars reported less satisfaction with their dogs' overall and leash-walking behaviors. Pit bull-type dogs were reported to be no less well behaved compared with all other breeds combined. Sixty-five percent of relinquishers reported some behavioral reason for relinquishment. Forty-eight percent of relinquishers indicated that at least 1 problem behavior was a strong influence on their decision to relinquish.

Administration of fluoxetine hydrochloride for treatment of urine spraying in cats can be expected to considerably reduce the rate of urine marking. The frequency of spraying before treatment is predictive of the spraying rate when the drug is discontinued.

Although cats can have individual preferences, our data provide a starting point for veterinarians recommending scratching posts to clients.
