I don't have kids and never plan on having kids, but my dad always taught me to love all animals. We always had fish and anoles when I was a kid and we always went to zoos.
I don't need kids of my own, though. I've been passing my love on to my one five-year-old cousin and will do the same with my other cousin once he's old enough (he's not even two yet). The last thing I want is for my own cousins to be afraid to come over my house because of my animals.
