To be honest ( hope this doesn't sound bad) but I don't think that cats really like to be inside all of the time. I know when my cats where in doors all of the time they hated it. But for the past 2 yrs they have being going out and they are much happier with that option.

Anyway i don't think there is a breed that is best for indoors they are all the same.

I agree with Amberlee that you are better to get a rescue cat, one that is in great need on a nice owner like you.
