Pam,

I've got 4 rescue cats and one of them does not cover up her "contributions" (nicely put)! I adopted her as a very skinny 4 month old kitten at Christmas, 13 years ago. They found her alone, and believe she was not properly raised by her mother, who would have shown her proper bathroom etiquette. She has never covered up, even with my 3 other cats showing her that they do it all the time. Note of interest: my other cats do not cover up her "contributions", only their own. I just clean up right away when I smell that smell!
