True, many more than that over the years. Birds, fish, lizards, turtles, dogs, cats, bunnies (outdoor hutch), and probably some others that don't immediately come to mind.
My firm rules for my kids about pets:
1. No invitations would be extended to close relatives of anything I'd paid (or would pay) an exterminator to rid our home of the wild version. Therefore, no mice, rats, hamsters, guinea pigs, etc.
2. No pets that needed live food. Nothing that ate live crickets or goldfish or "feeder mice." Period. No discussion whatsoever.
Did you have rules about acceptable pets?
