After a cat has eaten rat poison, the first thing you will feel is that the cat looks particularly irritable and is the kind of cat that runs around. In fact, at this time the cat is experiencing discomfort in the gut, even severe pain in the abdomen, and will be constantly screaming and purring in a particularly miserable manner. Then slowly the cat will appear to be foaming at the mouth, and this is the middle to late stage of poisoning. If the cat is not treated in time, the cat will die.
