honestly the weird poops only happen when i'm feeding him crickets. when i feed him mealworms he has very consistent, normal looking feces. when i feed him crickets it's always weird or discoloured in some way.
crickets so far have been nothing more a disgusting hassle. they poop everywhere and then eat their own poop. 90% of the time i find dead ones within 2 days of buying them, and the living crickets cannibalize the dead ones. their enclosures get totally disgusting, and are impossible to clean without throwing out the live crickets, so i only clean it when Tommy has eaten them all, and by that point there is cricket crap COVERING the bottom of the cricket keeper.
Tommy much prefers eating mealworms, and I know this seems contradictory, but they seem much cleaner and healthier too. Crickets it seems are almost always sick or dying, no matter which source I purchase them from or what I'm feeding them.
