Jackie: The prednisolone you use is a weak concentration, so you have to use more of it and buy more of it. Not so good for you or the ferret. Consider getting a prescription from your vet for a stronger concentration, such as 5 mg/ml, and filling it at a compounding pharmacy. I've been using this pharmacy for several years now for prednisolone, diazoxide, and azathioprine (Imuran). http://www.pethealthpharmacy.com/ Their prices are great and everything is compounded freshly for your prescription. When I get prednisolone from them, I actually get a concentration of 10 mg/ml. Anyone can call to get a quote on pricing for specific pet meds.
