We have trouble keeping hoppers in at pet stores here. The last feeding my pet store only had small fuzzies. My bp ate three in one feeding, and she's only about 140 g. I just give her 10 to 15 min from one to the other. She's also eaten 1 hopper and 1 fuzzy. I'm planning on getting a rat pair, so I can get her on a constant feeding schedule. Usually she'll let you know if she is full. If she doesn't eat it, she doesn't want it.
