My boyfriend and I have been discussing moving in together when our leases are up in the fall. We will be in a single family home or we aren't moving until we can. I have my 4 cats and he has 3. My two males and two females get along great and have all been together as a group for 5 years, my oldest is 10 and youngest is 5, they've been raised together from kittenhood. They are all DSH and one female is siamese. He has one male and two females, all DSH. The male is 5yrs old and has mental illness when it comes to separation anxiety and litterbox use. He also gets beat up by the two females and my siamese (he lived at my house for a few months as a fospice before my bf adopted him against my advice). The male lives in a cat condo when we are not home, he will actually go in there when we are getting ready to leave. MY BFs two females are not spayed and hate other cats, one is the others mother and they are 11 and 9 years old. We were thinking of giving my four cats run of the house with his two females which are used to sharing smaller spaces the bedroom and letting his male have his own space such as a screened in porch. This is such a temporary resolution though and I would prefer to have them all getting along, sans the mental male of course because thats not realistic. Any advice is appreciated, thanks!
