25
What are common causes of anorexia?
Renal/hepatic - toxin accumulation, any inflammatory/infection process causes pyrexia or neoplasia
26
What cats are at an increased risk of hepatic lipidosis?

31
How do you prevent refeeding syndrome?
Reintroduce feeding slowly - max speed of 1/3rd RER on day one and 2/3rds on day 2. Return to full RER on day 3. Monitor K+, Mg2+ and phosphorus.

36
What cytology is seen with exudate?
Neutrophils, or neutrophils and macrophages
37
What are the differential diagnoses for ascites caused by protein-poor transudate?

38
What are the differential diagnoses for ascites caused by modified transudate (protein rich)?
