Awhile back we took in a blind ferret that was a biter. We didn't really rehab her as much as we learned to manage her so she doesn't bite. Literally a wrong move and she'll give you a good hard nip. She doesn't go for the kill She has partial sight and used to bite if you came head on. If you approach her with a closed fist and let her smell you first she's very easy to pick up. I went to pick our little girl up and do her nails. She nipped at me. I tried to get some olive oil on her belly and she just wiggle. I settle for scruffing her. She screamed twice like I was killing her. I don't know what caused it. I finally had to get my husband to finish clipping her nails while I used to hands to hold her. I hoped holding her with 2 hands made her feel more secure. KG [Posted in FML issue 4780]
