Mary - 1 cc of hydrogen peroxide squirted with a syringe in the back of the throat will cause your ferret to vomit - but this is not the way you want to treat most foreign bodies. If you suspect a non-caustic poison that was recently ingested, I would suggest this. Or perhaps some foam rubber, etc. But for anything that may damage the lining of the stomach, it's better to work with it when it's in the stomach. Vomiting is a very forceful way to remove things, and you may tear the esophagus or cause more damage by inducing vomiting too hastily. Concerning Merritt and his food - Feeding kitten chow is not necessarily going to put on any weight, but in an older animal, the increased protein is harder on the kidneys. I would switch to an adult maintenance food and go with something like Gerbers Chicken baby food to put on weight. That's what we use at our house, and our friends use it to. Ferrets need to be force fed a little to start - just stick some in their mouths, and the 2nd or third time, they go after it like gangbusters....
