If it were me I would get some Crested Geckos if snakes are no longer an option. They are so much better IMO than leos. I have had leos and although I like them they just weren't my thing. Crested geckos don't need heat, they don't need insects, all they eat is crested gecko diet, a powder you mix with water. I find them much more pleasing to look at as well and their personalities are exactly what I wanted in a species. I really dislike keeping and feeding crickets.

I still feed mine insects because it's nice to give them variety and fun to watch them stalk their prey, they also grow faster when you include some bugs in their diet, but you don't have to. I will be picking up a colony of roaches at the Sept reptile show here in Tucson. Sounds disgusting but they are so much better in every single way than crickets. I'll need them in a few months...

Here are a few picture of my male and little tailless female cresties...okay more than a few.
