Thread: putting different temperments together

It's a difficult one I think, because it all depends on the individual cat's temperament and experience.
Kitten or older cat, male or female, it could go either way, as previous posts have shown.
But if your existing cat is mellow and laid-back, then that's a good start.

Kittens are sometimes easier to introduce because they are so obviously junior that the older cat does not feel so threatened, in fact they feel they are able to boss them about and establish a pecking order. Things aren't quite so clear cut with an older cat.

Having said all that, there's no reason why you shouldn't go with the female cat if you have set your hearts on her, especially with sensitive introductions.
