When I was a kid, my parents wouldn't let me have a dog, but they would let me keep a pet that fit in a fish tank... so I collected lots of fish tanks :twisted:
As of right now, I finally have my dog, as well as a few birds, but the only small critters that I have right now is a Chilean Rose Haired Tarantula named Willie, because he gave the woman working in the pet shop "the willies". I also have an Emperor Scorpion. She had 65 babies a few years ago, but I have nor bred her since. it was fun, but a lot of work to feed all those little scorpions.
In the past, I have had several breeds of snake, reptile and amphibian.
At one time I had an Argentine Horned Frog that was as big as a flattened softball and would attack anything...including me! Here is a picture of him when he was a little smaller.
