Since I have a permanent snake collection of about 70 and am a breeder, I usually do spend a little over $100 a month for snake food. The vast majority of my snakes eat frozen / thawed, and I normally order bulk shipments from Rodentpro.com. A full box usually costs $300 to $400 and lasts about 4 months at my house. Then I have to buy weekly live meals for my younger ball pythons. I hope to convert them to F/T in the near future. Since I mostly have corn snakes, and they brumate in the winter, my feeding expenses go way down at that time but up more in the summer when I have lots of babies hatching. In the summer I ususally breed a few of my own mice also, to get some of the pickier baby corns started on their feeding. Luckily, most baby corns take F/T for their first meal, and the rest always convert within the first four months of life. I wish my baby ball pythons were that easy to convert! Oh well! I love them anyway!
