sorry my dog poops on the outskirts of my grass, and never eats poop
You didn't answer my question, why do you believe cats are dirty?
As for the not eating or rolling in shit, that's only because he hasn't had the opportunity. They don't eat and roll in their own shit, they eat and roll in the shit of other animals. Not constantly, but they do it, it's a fact, it's hardwired into them as hunters.
I don't dislike dogs, I grew up around pedigreed German shepards. Until I divorced my first husband I almost always owned dogs (never just one) in addition to cats, rabbits, ferrets, rats, mice, hamsters, hedgehogs, etc., etc., etc. ...
I just don't understand unreasonable prejudice against one animal or another. It's been my observation that it's usually like any other prejudice, it's because people have been taught to dislike an animal, or they've never spent time around that animal and don't understand it, or they're inherently afraid of that animal. So which is it with you?
