Hey guys I have a young ball at 280-300g, and as far as I understand I should be feeding him about 10-15% of his weight weekly, so that's like 30-45g rats or mice correct? He's still on mice, and mice look pretty big for their weight so I do weigh them before offering.

I usually offer a 15-20g adult followed by a 20-25g one. Honestly despite their weight, the mice look about the same size as him, if not for the weighing scale I'd probably be feeding only 1 a week. But usually after eating the first one, he would just hide away and refuse the second helping. I know he can eat multiple meals hes even take 3 small ones before. Nor is it the size of the mouse, if I offer the bigger one first he'll take it, but the same thing happens he refuses the second helping.

Any cause for concern here? How do I up his intake? I know I should be changing to rats about now if I can but for now they arent available and I dont know why but a single 40g rat look pretty big for him. He has never rejected a meal before, but he gets full too quickly..
