Did you get another for company? Our 2 are getting on in years and they've been together since they were kittens we got them from a rescue at a year old. Although they don't really curl up together they are never far from each other and it worries me what we'll do when one leaves us.
I don't really want any more cats after ours but I also don't want to see the one left stressed in any way.
One of ours I think will cope fine the other I'm not so sure about.
I'm hoping we have a long while yet so really I'm musing at this point.
