u figure every 7 days = 4 feeds
You figure if u do 5 days. Your getting 6 feeds a month. Thats a extra half of what u normally feed him.
So if you do 31g mouse every 7 days thats 124g a month but if you do it 5 thats 186g a month. Thats over to half his body weight in food lol
Edit: We feed ours every 4-5 days
