Cats are uncomfortable with the smell of mothballs, and inhaling too much can even lead to poisoning. This poisoning cannot be resolved by vomiting and can even be fatal to cats in severe cases.

Because mothballs contain toxic substances such as dichlorobenzene, if cats ingest them, it can cause poisoning reactions such as vomiting, diarrhea, drooling, and convulsions, and in severe cases, it can lead to liver and kidney failure.
