well yuffie is about 3 months old now and she's starting to bite me, pretty hard too :/ when i let her out of her cage and i pull all her toys out for her she runs at me with her beak open and bites LOL its cute but it hurts >.< she doesn't do it to my partner and she wont do it when i've got friends around. is this called bluffing? and do i just ignore it? she's also getting really playful now too
