Yeah I wonder if that households with or number of the actual animals. If its households that have those as a pet I can agree. But if its number of pets in existance I would disagree. Most people have only 1 or 2 dogs. But a good majority of the poeple who keep fish have more then just two fish.
If they wounted individual pets the numbers would be in favour for fish. They probably just count houeholds with that pet.
I mean, Im just one person and have 100+ pets. If they counted Oddball the fish numbers would skyrocket.
