Hairball much?
Your cats are circling the tub, but don't count on them joining you unless you really are bathing in warm milk. And maybe you are. You cat people are cuh-razy. I should know. I have 14. What? Don't judge. My house may be full of hairballs and cat toys, but at least they don't leave the toilet seat up. Most days.
