Hey everyone, I have 2 cats which I have had together for 3 years now, they love to play and hang out together, well yesterday for no reason at all my older cat started to beat up on my younger cat.. I mean really beating up and I could not seperate them. the only way I could seperate them was with water.. and now I have to keep them in seperate rooms or else they REALLY fight.. and now last night the aggressive cat attacked my girlfriend.. I am really concerned. My girlfriend wants me to get rid of my cat now that i have loved for 4 years... please if anyone has any ideas let me know..
