My boyfriend is moving in and he has two cats. I also have a cat. I'm wondering what the best way to introduce all three is. I have read online to ensure that the new cats have a safe room and not introduce each other face to face for a while. What I'm more curious about is if I do the same thing with both cats right away. Or try to do one cat first and then another. We have about two months until he's all moved in. The cats he owns I wouldn't say are bonded. The one is not very nice and will occasionally still hiss at the other cat so I dont think locking them in a safe room together is beneficial. I do have enough space we could give each their own safe room or we could do one Cat and then bring in the other. Just wanted to hear what your guys thought were
