Vegetable Oil Cats. Adding olive or vegetable oil to your cat’s diet may help him if he is prone to dandruff or dry, itchy skin. To minimise the problem of furballs groom your cat regularly, particularly when it is moulting.
Cats do sometimes run, but it is not going to hurt any of them. It is best to leave a small amount of vegetable oil alone so the cat is allowed to lick himself by itself. As a breeder/ show cat enthusiast i do not add either to my cat or dogs diet.
