Literally put his arms around my neck when they opened his cage at the humane society. Hate to part with him, BUT can't go on like this. I am about to put down a small wood floor on a landing to downstairs area because I can't keep up with cleaning puddles daily. Please help if you can. It is very hard to bring a male cat into an established household.
Male cats tend to be more territorial than females and to insist on being the boss.
The females who were already there naturally don't like this very much. Bullet was quiet as he tried to scope out the place. Now he has decided to take over. I suggest that you remove Bullet from the female trio for a while and put him in a room by himself. Let the girls calm down.
