I've honestly never understood the incredibly limited live mealworm recommendations. 5-10 weekly sounds nuts to me, theyre insectivores and eat a huge amount of insects in the wild. My girl gets like 5-10 per night
(we give other insects too, but mealies are her fav by far!). I've yet to come across one convincing argument for why to limit them so drastically; i don't see anything wrong with feeding them nightly at all. It depends on the hedgehog, some are more lazy and prone to gaining weight easier than others, so keep an eye on their weight (it's a good habit to get into weighing them weekly for health check ups anyway), but you can absolutely feed them nightly if you wish.
