We're getting two indoor kittens today
We've got them a huge cat tree to run up and down and loads and loads of toys. I would recommend getting two if you're going to be out of the house alot so they have company and don't wreck the furniture! They're not much more expensive as a pair. We got some massive bags of dry food from Pets At Home which was pretty good value, but wet food doesn't keep quite as long as dry.
If you're going to rescue an older cat (yay, btw!) you'll almost definitely be able to get one who is already a house cat and so they won't have a problem adapting to your house. I wouldn't recommend turning an outdoor cat into a house cat as it can be really distressing for both of you.
The litter we got was a bit more expensive than most because it's corn based, which means it doesn't harm their digestive system if they eat it, it keeps the smells at bay without perfumes (which cats tend not to like) and it's clumpable and flushable! Got it from Pets At Home too.
