Thanks everyone.
Simba is very bulky, he weighs in the 40's-50's I believe.
We can't have a cat because he doesn't completely get along with them. He's fine if i'm right there saying "Be nice", infact I have pictures of him and my brother's cat, Orion. But i'd have to supervise them and be there 24/7 for Simba to be good about it.
