Other than the pets already mentioned, I just have 4 fish (3 are bettas). We used to have rabbits, hamsters, and hermit crabs as well as a couple of cats before we found out that our son was very allergic to them. You know, sometimes when I'm changing the guinea pigs' cage (it has to be cleaned every few days, so we all take turns) I imagine my sweet little corn snake with her mouth stretch around a big guinea pig butt! You know, her mouth just aint big enough - darn.
You could start a business by charging to view your snakes and then write off all the snake purchases and expenses on your taxes! That of course would include travel to and from reptile shows! Wow, why didn't we think of this before??
