What happens if a cat eats a bug?

It is generally not a big problem if a cat eats a bug, but frequent bug eating can cause issues. First, bugs may carry other parasites that infect the cat internally, so regular deworming is important. Second, some bugs may have touched cockroach or rodent poison in the home, so the cat may ingest a small amount of insecticide.

The owner should observe the cat’s condition, and if lethargy, vomiting, or diarrhea appears, take it to a pet hospital promptly.
