88 A 4-year-old female spayed domestic shorthair cat is evaluated for persistent inappetence. The owner indicates the patient has been abnormally quiet and non-interactive for the past few days. She last ate 3 days ago and has shown minimal interest in food since that time. The family adopted a new kitten 3 weeks previously; the patient has acted aggressively toward the kitten since adoption. The kitten is reported to be healthy. Clinically, the cat appears very quiet on evaluation but is responsive. She weighs 7.5 kg (16.5 lb) with a BCS of 8/9. Her temperature, heart rate, and respiratory rate are within normal limits. Mucus membranes are slightly yellow but moist, with a CRT <2s; her sclera are also yellow. She has a palpably enlarged liver and is uncomfortable with abdominal palpation.
