Why does my cat roll about in dust and sand outside when its sunny?

I've determined that my cat does this to irritate me. She rolls all over the dusty patio and then strolls into the house, walking around on the furniture and leaving her little dust trail behind.

Seriously though, I don't know why they do this. Maybe the sand in their fur somehow rubs against their skin and it feel good.

Who knows .... sounds like another question for Mother Nature.

Hey you two.. take a look at
THIS explanation.

Thanks Tree. Guess I'll just keep sweeping up after Jinx. I've been doing it for 18 years so far, so I can't imagine she's got too many years left to enjoy her sand baths. I'll let her bask in her pleasure to her heart's content

LOL, that's why I can not use the scoopable cat litter, Jerry rolls in it and eats it!!

.Because it feels good.

kitty, what do you use if not the "scoopable" sort of litter?
