Socks, a 15-year-old, castrated, domestic shorthaired cat, presented for anorexia, vomiting, and weight loss.
The owner reported weight loss of 9 months’ duration and a 3-day history of anorexia, lethargy, and vomiting (yellow fluid) once or twice daily. Socks’ appetite and activity level had previously been normal.
T4 concentrations can fluctuate throughout the day, even in normal cats.
According to the referring veterinarian, a serum biochemistry profile revealed elevated alanine transaminase (ALT) and blood urea nitrogen (BUN), although the actual values were not specified. Socks was treated with amoxicillin/clavulanic acid at 62.5 mg PO Q 12 H before referral.
