Twenty cockatoos with chronic feather picking disorder were screened for medical conditions and then randomly assigned to either a clomipramine or placebo group. Based on caregiver assessments and physical examination findings, treatment with clomipramine significantly improved feather picking when compared to a placebo at 3 weeks (P=0.028) and at 6 weeks (P=0.021). Clomipramine had no significant effect, however, on videotaped preening behaviors.

Design—Prospective open clinical trial. Animals—40 dogs with storm phobia. Procedure—Dogs received clomipramine at a dosage of 2 mg/kg (0.9 mg/lb), PO, every 12 hours for 3 months; then 1 mg/kg (0.45 mg/lb), PO, every 12 hours for 2 weeks; then 0.5 mg/kg (0.23 mg/lb), PO, every 12 hours for 2 weeks. Alprazolam was given at a dosage of 0.02 mg/kg (0.009 mg/lb), PO, as needed 1 hour before anticipated storms and every 4 hours as needed. Desensitization and counter-conditioning were conducted at home by the caregiver with an audio simulation of storm sounds that had induced a fear response during evaluation. Results—30 of the 32 dogs that completed the study had a degree of improvement, as measured by caregivers' global assessment. Two caregivers considered the storm phobia to be resolved. Panting, pacing, trembling, remaining near the caregiver, hiding, excessive...

Sample Population—40 cats in single-cat house-holds with or without elimination behavior problems (20 cats/group). Procedures—Camcorders were used to record the cats' behaviors at the litter box and other areas in which they eliminated during a 72-hour period. Use of space in the house was recorded by direct observation during 400 minutes of the 72-hour period. Elimination behaviors and other cat- and litter box–associated variables were compared between groups; litter box location with respect to inappropriate elimination was assessed. Results—Litter box location did not differ between cats with and without elimination behavior problems. An inverse correlation was found between time spent sniffing and the distance of the litter box from the central core area. Cats with elimination problems...

Animals—28 privately owned cats in 1 colony. Procedure—15 of the cats had 1 or more relatives present representing 5 genealogies. Each cat was observed in 15-minute intervals for 3.5 hours during the study. All occurrences of allogrooming behavior were recorded. At the onset of each 15-minute observation period and at 2- minute intervals thereafter, the identity and location of all cats within 1 m of the observed cat were recorded. Results—Relatedness and familiarity was significantly associated with the number of times a cat was within 1 m of another cat and how often a cat was groomed. For relatives and nonrelatives that were equally familiar to a given cat, relatives were significantly more likely to be within 1 m and to be groomed. Conclusions and Clinical Relevance—Familiarity and relatedness are significantly associated with a...
