Other 'useless' pets (Useless meaning they are more decoration than anything else):
Most, if not all, fish in fish tanks.
Cockroaches, tarantulas and scorpions.
A majority of lizards and frogs.
Most pet turtles and tortoises spend their lives doing nothing.
Plenty of cats might as well be furniture.
Small birds, and sadly a large number of parrots, are merely something to ogle at once in a while.
Many rabbits are fluffy pellet poopers.
Hamsters, gerbils, mice, rats, guinea pigs, all sit in cages running wheels and are left ignored.
There are plenty of useless, stupid pets.
Why someone likes an animal and wants to own it really shouldn't come into question unless it can endanger their lives and the lives of others (i.e. venomous/poisonous animals, large, predatory animals like lions and bears, or animals that one is highly allergic to).
