KG, Ive been a rescue since July 98 and have had to deal with alot of bitters. First whe he bites DO NOT give him treats! This is renforcing bad behavior. Insted put him in time out, like you would a child. Only do it in 5-10 minute intervals, but not in his cage, use a kennle. After 5-10 min. let him out again, and only reward him if he is good. This is posative rienforcement! I used it on a ferret named jordan who was sceduled to be put to sleep for being a bad bitter. Jordan was less than a yr old and had 4 prievius owner before I saved his life. It took no more than 4 wks to stp the biting. Remember be posative and consistant, only reward when he is good.
