I'm fortunate that my fiance doesn't mind my snakes. I think he even likes them. :-) He'll never like them the way I do but I'm fine with that.
Does your boyfriend think your animals are *gross* or does he just not understand why you keep them?
My mom is scared to death of snakes. My sister didn't like them initially (mom's irrational fear rubbing off on her) but I eventually got my sister to like them. She even took pictures with my BCI draped around her shoulders!
Maybe there's a way you can *trick* him into liking them. lol
