Thanks for the help.
I only worry that since my apartment (1+den) is small, 2 cats may get into a lot of territorial fights.
Oh and to the moderators:
I didn't mean to post this multiple times. I kept getting an invalid thread error every time I tried to post. Then I wouldn't see the post up, so I tried a few more times. Didn't think that all of them would show up at one time.
