I had tadpoles. in the house, in the kitchen, ewwww now, they make me feel sick. but not for very long obviously. i can still remember watching them now, then putting them back in the garden pond.
I also gave homes to caterpillars, until they fluttered around in the kitchen,
often worms, in a big container with soil, all for very short periods of time of course, but i loved them all the same.
I never took to snails, just ugh. no.
