ball python

Max:

I’d get a leopard gecko. They are small (8-10 inches), don’t require expensive items, they only cost about 30-40 dollars (much cheaper than an iguana) and they choose one place in their tank to go poop in, and then never use anywhere else to go poop.
They are very fun pets, and love to be played with and handled, and don’t hurt if they (for some strange unknown reason) decide to bite. They can’t climb glass, so they don’t escape very often. I have two leopard geckos, and they are both very sociable.

Cold Blooded Guardian:

Bearded Dragon is your best bet. There are different morph colors and the are really friendly and do not take up too much room and get about 24 inches maybe a little smaller. They make great pets and in my opinion are one of the best lizards to keep.
