Marbles (the kitty that came w/the house when we bought it) rolls in dirt. I've seen her do it in the summer, makes since, cools her off. She does it in the winter too. I just took this pic. You can't see ALL the dirt with pic, but trust me, she's covered in it. Then she pops herself on my bed and cleans herself. Where does the dirt go? ON THE BED! Non of my other kitties do this. Do yours? Why?
