Rosey is three months old, she is very energetic and very sweet. We've had our previous cat for three and a half years and he is not taking kindly to the kitten.he is being very territorial and has tried biting her.we have only had rosey for a few days but i feel like my cat is stressed out and i feel aweful.rosey is not neutered nor does she have her shots.she uses the litter box and eats solid food.
