Rhasputin, where do you get your feed? I used to feed Harlan brand food but I can only get it from reptile shows. Due to my busy work schedule I haven't been able to go and get more food from shows so I've been feeding vegetarian dog food (Nature's Recipe Vegetarian). It has a protein content of 21%. I've tried homemade mixes in the past but the mice would just bury most of it and I was wasting a lot of food (They would eat what they liked and buried the rest and I threw tons of it away when I cleaned the cages). I only have a few mice right now as I'm trying to get into breeding them for feeders again.
