Hi-- We have to ferrets, Brigid and Baby who are very alike is size and coloring and who share a cage with 4 other ferrets. One ferret has decided she likes another ferret's name better than her own and has started answering to it. Baby has been a resident here for about 18 mos. An older rescue we decided not to place. Brigid came to us as a foster care kit, who we decided to keep. Brigid was nippy and needed a great deal of handling. She has progressed so well, that she can be taken out in public to large gatherings and handled by anyone. She and Grany Malley are my so called Irish Twins, Grany named after the Irish pirate queen Grace Malley, and Brigid, after the warrior goddess, of druidic Ireland. While all this training was going on, Baby started answering to Brigid's name and impersonating her whenever possible. Brigid had a good deal going and Baby wanted in on it. Baby has spent so much time impersonating Brigid, Brigid no longer answers to her own name, and neither does Baby, who continues to answer to Brigid. KG I have renamed Brigid , Caleidh (cay-lee), an Irish party and have started to train her to the new name. [Posted in FML issue 3407]
