Peppermint can turn your cat into an excitement monster and excessive aggression is a common pet reaction to such a treat. And if you eat too much mint, vomiting and diarrhea will be added. It's just a special substance: it affects the brain through the smell and causes creatures with tails to rush around the house. "If, after contact with peppermint, a cat becomes nervous and attacks other people or animals, it is better to refuse such entertainment," veterinarian Irina Baklanova told the section. But if your pet tolerates peppermint calmly and you want to please him, do not overdo it. It is enough to give a treat on a toy about once a week. Forward to your cat loving friends.
