Our cat likes laver very much and protects its food. Is this ok?

No problem, cats can't eat chocolate, coffee, tea, onions, bones, monosodium glutamate, smoked products, grapes (raisins), undercooked fish, tomatoes, acidic vegetables and acidic fruits (such as oranges). Cats can't eat peppers-! ! When I was a child, I fed him Chili peppers and ignored me for a few days.
