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.

Feline acute patient physiologic and laboratory evaluation scores and other prognostic factors in cats with first-time diabetic ketoacidosis.
Median BG was significantly higher in non-survivors (431 mg/dL) compared with survivors (343 mg/dL) and BG predicted mortality. For every 1 mg/dL increase in BG, the odds of death increased by 1.004.

Head tilt in 6 Ankole-Watusi cattle (Bos taurus ankole) with chronic exudative cornual sinusitis.
Clinically, 4 of the 6 cases had concurrent otitis at the time of initial clinical observation. Medical management was the standard across all cases with limited surgical success in 2 cases. Due to intractable and progressive clinical signs despite treatment attempts, euthanasia and postmortem examinations were performed.

Factors Associated with Medication Noncompliance in Dogs in New Zealand.
Medication noncompliance was recorded for 47% (71/151) of owners. Increasing dog age was associated with better owner compliance. Forty-seven percent (71/151) of owners reported that "nobody" showed them how to administer the medication. One-third of dog owners (47/151) reported challenges in medicating their pets. The most common reason cited by clients reporting challenges was a resistant pet.

Adjuvant Chemotherapy Is Associated With Prolonged Survival Time in Small-Breed Dogs Undergoing Amputation for Appendicular Osteosarcoma.
The median time to distant progression for all dogs was 265 days, with no significant difference between treatment groups. The median overall survival for all dogs was 270 days, and it was significantly different between amputated dogs (150 days) and those also receiving adjuvant chemotherapy (353 days). In our cohort, osteosarcoma in small breeds behaved as aggressive as in large breeds.
