My cats (Tosspot a.k.a. "Tossie" and Misty)never go out in the Mud (or the barn, or the street...) They don't fart either, maybe due to the fact that, like Kat's cats, they eat Iams and Science Diet (the over-the-counter equivalent of what Kat gets from her vet). Mine are 17-1/2 and 13-ish years old and even if they were malodorous, I'd like that better than not having them around. They probably are wondering what they should feed ME..... *BG*
