I've had a few Iguana's, they are very hard to keep alive. You have to take it out of the cage or it will 1.) Get VERY MEAN! 2.) DIE because of lack of attention! They are weird as far as pets go, not like a gerble or anything like that. One of my ex's has two, one was smaller and it was cool. I would walk through the mall with it under my hat with its head sticking out. The other one she had was HUGE and its tail was broke because it was in a small cage and it broke due to bad circulation. IT was a MEAN SOB. There was no dog around here that would mess with it...... they can be fun pets if you have the time to spend with one. 20$ does sound a little cheap, but if its a small baby then that should be about right.
