Amy, when I found Sassy on the street, my hubby said "don't even think about it, find her a home" She'll be 6 in August.
When I told him I was getting Missy from a coworker he said "if you bring another cat home, I'm leaving" She's 5 1/2 and hubby's still here.
My husband came from a cat hating family so he didn't know any better. I think his family is afraid of cats! Needless to say he loves the cats now and I've even heard him tell people how great cats are!
Good Luck whatever you decide to do puppy or kitty.
