Cant remember which one Sophie is, but if yours are indoor cats like mine, they can be content to live in one room on their own only. Like your bedroom or spare room, providing you have enough toys, cat climbers and so on for them. I have a stud boy that has adjusted to being on his own all of the time (with loads of cuddles from his mum of course) its just like having their own pad. If Sophie is an outdoor cat that might be a different matterconfused:
