Dear Concerned Sister Actually, I think the best thing you can do is to give your sister the tools to solve the problem herself. You have already given her some questions to ask about, she has already shown her own concern about the size of the cage, and you are going to give her an excellent book on ferret care. Now give her a little time to work with the teacher to make sure the ferrets are being cared for properly. Remind her to approach the teacher with respect and not confrontation. She should let him know her sister used to own ferrets, so she has some familiarity with their needs. It IS possible for ferrets to be properly care for in a school environment; I seem to recall there have been teachers on this list that have done so. Only if the ferrets are being kept in an unsafe or unhealthy environment should an outsider get involved. Hopefully that will not be necessary! Linda Iroff a little sister [Posted in FML issue 4500]
