We currently have two who get on pretty well. They're both rescue cats and I'd quite like another one - I'd like to adopt an older cat, since they struggle to find new homes. DP is less keen, thinks two is best and that it might not be fair on the two we already have, or on the newcomer, who might get bullied. Our house is large enough for them all to have their own spaces, if we did have three, but obviously that's not the only consideration. Does anyone have experience of having several cats and if so, how has it worked out?
