Crickets are favored insects for feeding frogs, but they soon tire of them if given too many. Too many crickets in a frog's diet also can cause digestive problems because crickets contain "chitin," the same bio-compound in human nails and hair. Frogs that ingest too much chitin can develop "impaction," which is difficult to cure and almost always causes death. To prevent this, alternate the frog's diet with flies and other soft-bodied insects does this include toads lol so yes to much can kill see you dont know everything ive learnt a valuable lesson as i was giving my toads 2 boxes of crickets 1 box hoppers and calci worms a week but this is for 2 toads as ive just got them mybe im feeding to much my abf is on worms with caclicum and d3 now they have settled in im now going to feed them with throngs so i know what they are eating also i weigh mine you see i do have a valid topic or arguement with you moderation
