My male Chico is the most personable chin ever now. He loves a good scracth on his tummy, nibble on your finger while your doing it. But if he gets to worked up or in an unfrimilar envirnment he will snap/nip a little bit. And it does hurt a little.
Right now when he sees his girl out to play, (seperate cages) it can get him so worked up he starts haveing seisures or going crazy at least. So if she comes out i have to put him in an small animal carrier away from the play spot, so he doesnt have any problems. He was in their jsut yesterday when i came up to the front to check on him and he bit me.
Hes still the msot lovable little guy, but occasionly they might get to the point of doing something liek that.
