To Peter Graziella concerning young Morkette with vomiting: Peter - The first thing that I would think of with a young ferret with projectile vomiting and abdominal pain would be an abdominal blockage. As a minimum, I would suggest a CBC, serum chemistry panel - to see what changes are going on in the blood and how the vomiting has affected Morkette systemically, and abdominal radiographs, with a Barium series that may pick up a blockage. If there is any sign of a blockage, I would make sure that she is stable and go right to surgery. Has there been any blood in the stool? Has it been tarry? Or has there been any pain on defecation? I have found fecal cultures to be unrewarding and generally a waste of money. I am not really familiar with E. coli enteritis as being a problem in ferrets. Most cases of diarrhea in young ferrets are due to them eating something that they shouldn't and I always start them immediately on Laxatone and Amoxicillin 10-20 mg/lb. If there is sufficient damage to the lining of the intestine, you can have absorption of bacterial products and/or bacteria from the lumen of the gut, which adds to the problem. The antibiotics seem to prevent a lot of problems in these instances. Peter, I urge you, if you are not think of a foreign body, let's turn our attention to that possiblity. A bacterial enteritis in an animal on antibiotics is probably not life-threatening, but a foreign body definitely is.
