How often do you wash your cat/dog's food and water bowls?
When I was a kid, we had cats and honestly, I don't remember their bowls getting washed with any sort of regularity. With my cats now, I'm washing their bowls in the dishwasher whenever they start looking icky. (I do rinse the water bowl when I fill it up.)
Also, how often do you wash pet beds/blankets? I wash mine whenever they start looking really hairy...which, having cats who shed like it's their job, happens almost instantly.
