Shalom All: I've been using feline hairball stuff with my ferrets for ages. They love it (the cats wouldn't touch it if they were starving....) and it works well with no problems. Here in Jerusalem we have cold winters and hot summers, and since I don't use much heat my fuzzies get really thick coats and when they blow it is really something to see. Anyway, catlax and ferromalt are what I use. Just don't over due it. I use it once a week for prevention. Question: The only killed rabies vaccine here in Israel is killed of hamster origin. Is this OK to use? None of the vets I've talked to will commit themselves. I need an answer, please.......
