No, cats should not eat fireflies. Fireflies, also known as lightning bugs, contain a chemical called lucibufagins which is toxic to cats. If a cat ingests this chemical, it can cause vomiting and foaming at the mouth. Even though one firefly wouldn’t cause serious harm, it is still not safe for cats to eat or ingest them. It is best to let your cats admire the fireflies from a distance and not let them eat them. The chemicals in the fireflies are toxic and can cause digestive upset if ingested. Additionally, just one milligram of bufotoxin (the size of a few sugar granules) can kill a cat! So it is best to keep your cats away from fireflies and let them admire them from a safe distance.
