I believe cats (and rabbits) contain a natural deodorant in their fur, and cats for certain have a natural detergent in their saliva, which would eliminate all "animal skin odours" as they groom. Our rabbits and cats all smell lovely, no nasty niffs at all there.
(Cats' litter tray does have to be cleaned very regularly, however)!
My Mum did have a cat many years ago who was a pongy chap. He was the runt of a litter, funny looking and no-one wanted him. Teeth all askew, halitosis and quite windy-ish. But his fur still smelled lovely, and he was such a dear little cat and had the loudest purr I've ever heard in my life! He was christened Norton as a result (because he sounded like a motorbike engine). 
Cows are not normally classed as pets, and if you choose to live in a farming community, then you do have to expect a certain amount of farm-related faeces, so I'm sorry, but have no sympathy there, TBH. And unfair to class a dairy farmer as a "useless f*er" as they are doing a job. Most people in the country consume milk, cream, cheese, yoghurt, buttermilk, etc. (Except, of course, the vegans, who are in quite a minority, I think).
