Lissette, you have a very traumatized and unsocialized baby. Hopefully she is not also aggressive in her temperment (breeding). Deafness is the least of your problems. You need expert advice from ferret people who have dealt with vicious biters. Troy Lynn, Alicia, perhaps Randy, and who knows all else. I hope they reply. I also hope that many people realize that with an animal like this, its not just all about socialization. This sort of agression is a serious problem and the old "have patience, show love, show nice hands" does not always work. I've come across two incorrible biters. One was a rare find. A Path Valley kid only 7 weeks old, I was the first home and he was just as you described. He was no diff than a wild animal. It was almost neurological too. The pet store could not sell him as was, and came to me for help. We gave it a year. There was only minimal change. It's important to note that I never used gloves. And now I think that was a mistake. I had a baby on the way, so I could not keep him and gave him back to the pet store owners. I have no clue what happened to him next. The nice pet store owners and I, failed him. The other biter I came across was not unusual or bred poorly. He was indeed vicious ... from severe prolonged abuse. It took over 6 months, but that ferret was cured. I always used gloves. That was important. It was imperitive that the animal not sense any fear from me. I had to be calm and confident so she could feel my love and acceptance. I had to handle her as much as possible allowing her to lick treats off my gloves and to see that hands were nice. And I mean constant picking her up out of her cage for treats and pets. I mean sitting with her several times a day for long petting sessions. And lots of exposure throughout the day so she saw me a lot. I did not allow her to roam free with me walking around to give her any satisfaction in chasing or biting. I didn't want to accidently reinforce any bad behavior. I took an agressive approach in other words. With the other ferret, I took the old fashioned approach. I think the old fashioned approach works for sweet babies with terrible social skills, and or fear biting .. but not in the two cases I came across. You are right to take the deafness into consideration. Aggressive ferrets who have been bounced around or mistreated and who are also deaf seem to take a bit longer to rehab. The deaf are open to abuse because most of the time, people don't know that they are deaf. Each and every time they come up on them from behind, each and every time the ferret does not react as they expect and each and every time they discpline the animal for "not listening" is terribly traumatic for them. Very emotionally scarring. But reversable in most cases. Just take the deafness into consideration as you would with any deaf ferret. Take extra, extra care that this little one always sees you coming. If they have a strong startle reflex (like many of the DMK's), take precautions for that. Calm, calm, calm. Consistent, consistent, consistent. Give no strong feedback. Even positive ... keep it low key and sweet. If your ferret calms down, has no startle reflex, has no fear, then you can use big facial expressions for things. But for right now, don't. [Posted in FML 5952]
