Q. My ferret has a chronic prolapsed rectum and his doctor gave him dewormer twice now but the problem persists. He also has fluid build up in his belly.

A. There could be several reasons for accumulation of fluids in the abdomen in ferrets, but the most common is dilated cardiomyopathy (a heart condition causing heart failure).
The prolapse rectum is probably due to chronic diarrhea, which could also be the cause of the fluid accumulation.
Chronic diarrhea needs to be investigated properly, and several treatments need to be given in order to try stopping the diarrhea.
