I have a nearly 4 year old neutered female cat. I have been thinking about adopting another cat, but I fear they won't get along. Current cat is not really social, rarely likes being touched, instead requires attention: playtime, being near (but far enough), etc.
What are your experiences with second cats? Are there age / gender combinations which are the safest?
Edit: thanks for all the replies! Forgot to mention that she is an indoor cat.
I added a second one and had a lot of trouble. Years for them to coexist relatively peacefully. I also recommend people foster to ensure it’s a fit before committing, it can be difficult if they don’t get along.
