Hello. I have just taken in a cat, about a year old, which was left when the family next door moved. She is great with us, kids and adults, but is very aggressive with the other cats in the house. I hate to lock her ina room, but I have becasue she is attacking the 2 older cats in the house, also about a year old. She literally attacks them and we have to brak them up. She also hisses and growls at the 2 baby kittens in the house, about 6 weeks old. She has such an excellent temperment with people, and I really do not know what to do. Should I keep her closed ina bedroom by herself or should I take her to the local shelter? Like I said, she is so sweet to us, I would love to keep her, but not at the expense of my other cats health. We did have her checked at the vet and got her shots. But she just attacks the others and we are unsure of what to do. Please help! Steve
