First thing you need to do is stop wearing gloves. Ferrets need to smell you and be able to feel you and get used to you. Gloves should only be used in very rare cases and as minimal as possible. When holding your ferret you want to make sure that you NEVER put her down because she bites. If she bites and you put her down that is only telling her that she gets what she wants for biting. You need to keep holding her until she settles down and then give her what she wants (ex: down to run, a treat, a toy, etc). Another thing you can do when she bites it scruff her and tell her very firmly "NO". You know that you have her in a good scruff when she yawns. Again after she settles down you can stop the scruff and pet her and talk nice to her again. If she gets all crazy again and bites or tries to then scruff her and tell her "NO" again. They can learn to be very well behaved and happy go lucky little guys but it does take some time and some can be more stubborn. How long have you had her? Where did you get her from? Make sure no matter what you do, you NEVER hit your ferret!! Some people will tell you to flick them on the nose, but that is only going to make them lose any kind of trust in you and will make them more prone to biting. I used to volunteer for the ferret rescue and have met a few ferrets with all kinds of different issues. One of my fuzzbutts was actually very abused when I adopted her and she had a huge lack of trust...it took alot of time and effort but now she is very sweet and loving and loves to give kisses.
