I dated a guy years ago who had a bunch of reptiles and amphibians as pets. He had a couple Gila monsters in his bedroom (safely enclosed in glass), plus a turtle and a couple other ones. I was OK with that. Then one night, he had a tarantula that he was just keeping temporarily for someone. I was NOT OK with that! He stood up a book in front of its enclosure so I didn't have to see it. Still didn't sleep well that night... Thankfully, it was gone the next time I was over there!
