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.
My tortie forcibly made my void her friend. It's the only cat he allows to sleep with him out of the 3 others. Not because he wants it, but because she doesn't understand that no means no.
She would go and try to get in his catbed, he would bite her. She would get out only to try another angle, get bitten, try again, until he just gave up and let her in.
Now he doesn't fight back for his personal space anymore.
