I'm having the same problem with my 2 ferrets. Ever since Indy had his operation, Waldo goes after him. It's not nearly as bad as the incident previously mentioned, but I would appreciate any advice being sent to me as well! Bitter Apple just isn't working. They used to get along well, and I'd like them to again. Thanks for the help. Becky, Waldo, and Indy (who's feeling MUCH better!) [Posted in FML issue 2208]
