I’ve had quite a few cats over the years. The all black cats had issues with diarrhea, and had an odor about them that I’ve never found in calico, long hair, short hair, non-predominantly black furred cats. The all black cats were a single litter, and my recent experience is with a stray I took in.

I have a all black cat and she doesn’t have any odor problems. Now I’ve had a long haired fur ball cat and it’s feces stunk horribly. I guess it all depends what you feed them, how much you bathe them, etc.
