oh yeah - the first photos in this thread show the hoppers being full, i don't fill the hoppers anymore. everytime i forget to close the door to the rat corner my damn dog empties the hoppers. so now i just give them a little dish full of kibbles/seeds/mealworms/whatever. they always tip the dish and spread the kibbles all over though, so i'm going to eliminate the dishes and just throw stuff in there. they're pointless, just another thing to clean.
