The question https://pets.stackexchange.com/q/34455/330 was closed with reason "squirrels aren't lets". I don't understand: I used to have a squirrel as a pet, many others do the same, many shops sell pet squirrels, and [Wikipedia](https://en.m.wikipedia.org/wiki/Pet)
lists rodents as common pets. Why are squirrels declared as non-pets on this website?
