Thanks for your help! I do appreciate it. I just now weighted them (I have a postage scale for my ebay sales). The girl pictured weights 200 grams. Her brother weights 198 grams. Her sister weights 178 grams. They are each 24 inches long. They last ate on Tuesday. Not sure when they last poo'd as I don't record those. Their hopper mice are averaging at 5 grams a piece. So maybe 2 of the hoppers twice a week? 4 total for the week? Next time I go to a show I can pick up some larger food. What size of food should they be eating? I buy from Rodentpro and they go to one of the shows here in Ohio once a month.
