The frequency of oral famotidine administration influences its effect on gastric pH in cats over time.

Background: Famotidine is commonly administered to cats. Prolonged famotidine administration results in decreased efficacy in humans, dogs, and cows, but the long-term effects in cats are unknown.

Objectives: To compare the effect of 2 oral administration frequencies of famotidine, twice daily (Group 1) and twice daily every second day (Group 2), on intragastric pH and serum gastrin concentrations in cats.

Bartonella henselae, Bartonella koehlerae and Rickettsia rickettsii seroconversion and seroreversion in a dog with acute-onset fever, lameness, and lymphadenopathy followed by a protracted disease course.

Following recent tick exposure in Arkansas, a 2-year-old, female spayed Labradoodle was examined because of a one-week history of lethargy and shifting-leg lameness. The dog was febrile, had prominent lymph nodes, dull mentation, a stiff gait, and left forelimb lameness. Thrombocytopenia was the only initial hematological or biochemical abnormality.
