To Christine - > The reason I was asking is our male ferret (who has b >een neutered and descented) has been extreemly aggressive towards our female (a >lso altered) Oops - I was under the impression that Milo was intact. Well, now you do have a problem. (Not that you didn't before). What we appear to have here is a behavioral problem. I have a similar problem at home iwth a small older female, and two younger, larger neutered males who delight in tackling her and frightening her. What we have been doing over the last few months is to make sure that they are not left together unsupervised, and have been in close proximitiy when they get together. Each time they get together (which we encourage), we talk to them and keep our hands down near them so that they know we are watching and prepared to intervene if necesary. It seems to be working - although they sometimes still get to her, the number of times that ey interact peacefully is on the rise, and negatively is declining rapidly. I do't think I'll ever trust them completely around her, but at least we don't have to come running whenever they come in contact with each other. Bruce Williams [Posted in FML issue 0963]
