2 cats to new home with existing cat
My boyfriend and I are planning to move in together. He has one male cate (he's 17 but pretty much a spring chicken) and I have two cats (boy is 7 and girl is 3). Mine get along great but we're worried about introducing all three of them. My boyfriend and I have been together for 5 years so they all know each others smells but I am not naive enough to think that will make it all okay.
I am moving into his house, which is much larger than what my cats and I are in now but the layout is pretty much two large rooms, one on each floor, so there are limited options for sequestering. I was thinking about maybe putting my cats in crates to start? Though I'm not sure if that is a good idea; I'd love any introduction suggestions!!!
