We've got a snake cos it's got no fur - one of the kids was a proper respiratory cripple as a child.
It's a gateway pet though, we've now got a lot of lizards and amphibians. None of which would have been my idea of a good pet, but, actually, I'm a convert:
they don't care if you don't handle them, unlike hamsters which get viscous or rabbits which get nervous
they like being handled for the warmth
once you get the housing set up correctly they are minimum care
there is a bit of "cool" factor at school
you can leave them for a few days at a time, as long as they have water
the vivariums are all planted up and look nice.
The food comes in the post so it's very covid friendly.
Minuses -
occasionally they get out and so do the crickets for the lizards. We've always got them back though, the kids are really very good with their pets.
you need an exotic vet nearby
