Reptiles and amphibians make unique pets. They have few emotional demands, but they do have precise physical needs. And because pet reptiles and amphibians are in cages and can't seek food on their own, they depend on you for the right nourishment. Some reptiles and amphibians have considerably long lives, so be prepared for that. (Reptiles and amphibians are also known as herps, from herpetology — the study of reptiles and amphibians.)
