An other option would be a Mokave or other large cat, I think they mature around 30lbs. that would make someone think twice
Plus I'm thinkin' low maintinace, litter box and at feeding time just let it out the back door....Im sure it could hunt up something for dinner
Ok cat people, small mamal and children lovers, the feeding comment was in jest....still a cool beast to have around the house don't ya think?
