So ... i have a 9 month old cat that i have had for 5 months and she hates my 2 year old cat STILL. They fight all the time and it freaks me out! My cat only likes me nobody else shes really sweet to me but if another cat or anything comes around she hisses and bites and yeahh
i would try to train your cat .. mabey try telling him/her no sometimes when the cats fight, but another option would be to get a cat whisperer
