He's maybe a year old, and I've just recently switched him to adult mice. I was feeding him once a week with two young mice (small adults/weanlings). Anyways, he's almost always hungry. I've bumped it to an adult every 5 days, but within 2-3 days of eating, he's acting hungry again. The adult mice are at his maximum limit of size, he takes awhile to eat them, and they leave a noticable lump for about two days after feeding. Why does he always act hungry? My balls are all well-fed as well, but I don't have these issues with them, and I haven't bumped them to the max size rodent that they can handle...
