I have some more cat behaviour questions. I have had cats before, but never two at the same time. I've also never had a kitten, just adult cats.

In October, my boyfriend and I have decided to pick up two cats. We're thinking ideally an older cat and a kitten.

I'm just wondering, if we get the cat and a kitten, or if we get two adult cats, when we leave for work should we separate them? We don't have any other pets and I know problems can occur when you already have a pet and you introduce a new one. But when they're both new, could there be problems? We will definitely make sure whichever cats we choose will be friendly towards other cats. I just don't know if there are any precautions we should take before they get use to each other.
