I got it!! When you have feeder bugs, just feed your cats less so they stay on the hungry side. This way if you drop one they will snatch it up for a snack.

And as for feeding the toads, mine also LOVE moths, but you have to cut the wings off of 'em so they have a chance at catching them. Or you can just leave the wings on and watch the toads stare at it while it flutters about in the viv.
