We have 3 kitty brothers and 1 kitty sister. They are different ages. Rosencrantz and Guildenstern are 12 year old brothers. Saber is 1.5 year old and 15 lbs. Willow his girlfriend
he just gives her loving lol. Galen is only 3.6 lbs. They are really good with him. My old guys have bopped him but not hurtful, to get him to stop chasing them. Saber just slowly runs around the living room and lets him chase him. He never goes after him. Willow . . . she is my little feral but she lets him love her. They are too funny. I would not see a problem bring another kitty into your home. Good luck
