Archives Highlights:
The 4 prokinetic drugs metoclopramide, cisapride, pyridostigmine, and capromorelin do not increase fecal output or food intake in healthy New Zealand rabbits (Oryctolagus cuniculus).
Every day, rabbits produced a median of 75 g (range, 9 to 145 g) of feces, 226 fecal pellets (range, 12 to 412 pellets), and 151 mL (range, 5 to 420 mL) of urine. Metoclopramide, cisapride, pyridostigmine, and capromorelin had no effect on fecal production (both weight and number of pellets), food intake, urine production, or water intake compared to placebo at 24, 48, or 72 hours after administration.
Litter box size and litter type preference and their associated behavioral changes in cats.
Our findings indicated that cats preferred litter boxes measuring ≥50 cm as well as clumping clay litter. Moreover, a comfortable litter environment combining these two elements promoted normal urination behavior while improving house-soiling (both urination and defecation).
Use of Dog Serologic Data for Improved Understanding of Coccidioidomycosis: A One Health Approach.
The overall seropositivity rate among tested dogs was 37.6%. Average test positivity rates in states with =0.5 tests per annum per 10,000 households were 35.4% (Texas) to 74.1% (Montana). For these states, average annual incidence per 10,000 households was as follows: Arizona (86.8), New Mexico (0.89), Nevada (0.78), California (0.75), Montana (0.63), Colorado (0.41), Oregon (0.41), Texas (0.38), Idaho (0.37), Wyoming (0.34), Utah (0.32), and Washington (0.26). Human incidence in California and Arizona between 2012 and 2022 was significantly correlated with dog incidence.
Performing an Avian Physical Examination in Practice
As with mammalian physical examinations, it is important to develop a consistent order for the avian examination to thoroughly evaluate each body system. Some components of the physical examination differ between avian species. For example, cloacal palpation is performed in chickens, but not in parrots.
Effective treatment with afoxolaner (NexGard) of Trixacarus caviae in a pet guinea pig.
The animal was treated with a single oral dose of 2.50 mg/kg afoxolaner, and the lesions, presence/absence of mites, and intensity of pruritus were evaluated periodically until 2 months post-treatment. A week after the medication, the lesions were milder, but pruritus was still present and was attributed to the healing process. Further examinations showed significant improvement with the complete remission of clinical signs and no mites at the microscopic examination after 4 weeks.
