I feed 2000g plus females mice and they are perfectly fine. Chunky butts... They get 3-4 mice every 10-14 days, maybe less if I'm running low and feeding babies is priority. Sometimes they get 5 or 6 if I just want to get rid of mice and they're still taking them with gusto. They tell me when they're done.

Plus, I get live medium adult mice for $0.47 each, same for frozen. Definitely not going to Petco and paying 2.99 per HOPPER. Dinky things.
