i'd say give it a shot, since you already have them. maybe give them just a few and watch them eat them. if they don't eat them all at once, take bowl away and if you find any in there later, you know they have the same problem as my toad. if you find nothing, then it's a green light! they're a nutritious feeder, if they stay food and not adventurers taking a sight-seeing trip through digestive tracts.
