BIG, I asked my vet today about the correct dosage for pretreating with Benadryl and she said the dosage they use for cats is 1mg/lb. And since we go by, "When in doubt, treat like a cat", that was the dosage she recommended for ferrets. If anyone has a dosage specifically for ferrets she would like to know it. [Moderator's note: I checked and you are right. My initial comment was due to my misreading your post. If anything they can probably take a higher amount. Sorry. BIG] BTW, I think you do a wonderful job moderating the list. We all appreciate the time and effort you put into it. I'm sure many ferrets owe their good health and happiness to this list!
