Hi,
I live in a one bedroom flat, go out to work all day, and have two wonderful indoor cats. I have to admit they are Singapuras, not moggies. I've had them from kittens, they are excellent company for each other, but still have plenty of time for me when I get home. I am very grateful that I took the 'two for company' advice, though I understand that not all littermates remain as close companions as my two boys once grown. I also wanted a breed that was suited to indoor life, and that was also fairly lap and people friendly.
I also tried local rescues whilst researching, and found that most were reluctant to home kittens where there was no one at home during the day, and said they didn't have adult 'indoor' cats, and it wasn't fair to try and turn a previously indoor/outdoor cat into an indoor one. Which is why I ended up going the pedigree route, as the kittens were about four months old when they came to me. I live on a busy main road, with the car park for the flats out the back, so the cats have to be indoor.
If you can find rescue cats that need indoor homes that would be great! In addition to general rescues you might also consider 'breed' rescues, for the reason that they may be more likely to have been brought up as indoor cats. You might also find in any rescue, breed or moggy, cats that have been put up for re-homing because they don't get on with other cats, and need to be the only cat in the household. That might suit your situation.
