Can Cats Eat Grasshoppers. Cats often ingest fleas while grooming, which can cause a tapeworm infection. I have personally observed my domesticated cats preying on cockroaches, crickets, grasshoppers, butterflies, and moths.
Bees and wasps, and certain ants and spiders, give a painful sting if threatened. Since cats cannot digest grass, it makes them vomit up the grass and any other bad food they have recently eaten. They are usually harmless for your cat to eat, although too many of them could lead to an upset stomach.
Hiding in plain sight is a main mode of protection.
Since cats are a lot smaller, spider venom can damage them a lot more. Cats can eat bugs with no ill effects, but there are risks. Grasshoppers lay multiple eggs to counterbalance the several natural predators they encounter. Some of these insects hunt and kill grasshoppers, while others simply wait for one to die and then eat it.
