well things that can be for life are things such as bearded dragons, anoles, leopard geckos, crested geckos (prefers height though..), or even pacman frogs, tree frogs, fire bellied toads, etc and for amphibians if you hold them make sure you wash your hands before and after but thats a general rule for reptiles to..but frogs for sure since there skin is sensitive..oh yea and if you do get a fire bellied toad there skin has toxins so like i said make sure you really wash your hands..
