GEnie Pet-Net RT Barry - I can unerstand your concern - having recently experienced a similar problem with one of ours - 36 hours being off food, very lethargic, and with a couple of periods of vomitting. Hopefully, this has all passed by now, and your ferret is well. As near as we could tell in our situation, was that a couple of them got into some "forbidden fruit" - in this case some french fries. One it never bothered - while the other must have a particularly delicate stomach. Scared the daylights out of us as it was so sudden and because of how quickly ferrets can deteriorate, health-wise when they become ill. It turned out fine - you've done the right think by keeping in touch with your vet. If it continues beyond 48 hours (according to our vet's and other's advice) - then more specific vet treatment is appropriate. Good luck! Ann Gruden ======================== GEnie Pet-Net RT Barry - Barium is in order, but it still does not show everything that could get caught. My method of determination: put 25 pieces of food in a bowl. put in pure, clean litter. mark the water bottle level. leave this way for 12 hours. if food has not been touched or stool not passed, then there is something in the stomach or intestines. Exploratory surgery is recommended before the ferret deteriorates too much. If water has not been touched - get the ferret to a vet IMMEDIATELY!!!! If food has been eaten but not passed, give some Laxatone or Petromalt (hairball remedy) and give it another 12 hours. If no stool, - exploratory. If stool and no eating, check the stool for nasties and/or foreign items. Try and force Laxatone. Sometimes the foreign item will pass with time on its own, but more that 48 hours and the ferret might be too weak for surgery. good luck and keep us posted. Pan Grant [Posted in FML 0208]
