Helo everyone, i had 2 cats for almost 1 year and they were best friends that all time and 2 week ago I dicided to adopt a new kitty. And after a week two cats got along - a new one and one whoch i had earlier. So third cat was left and they are not frinds anymore, they dont play, they dont sleep together as they used to do. I dont know what to do. I really hate myself now for adopting that new cat becouse one of my cats does not have any friends. He's angry then his ex friends is close. And he got more nervous and angry, begs to go outside (beafore that he was too scared to go outside). If you know ehat to do, please help me, I really need your help.
