One of my friends had one, and it was the worst pet ever. Untouchable spikeball all day, then when everyone was asleep it wakes up, gets in its mouse wheel and starts shitting and running. It's baffling how something that small can stink up an entire house.
They're also dumb as shit and literally forget you exist when you leave their field of view. If you're already resigned to an animal shitting in your house at least get a cat or something that will still make a mess and wreck your furniture but will occasionally be nice to you.
