I have 4 snakes. I have bred my own mice before, but it seemed like I was spending more in Aspen bedding from all the cleaning than any saved money by having my own feeders. I buy my pinkies from my local shop - they are packaged "Mice On Ice". They are about $7.50 for 6 of them. I buy live adults and pre-kill - around $1.25 each. I am starting to wonder if I would be cheaper again - buying larger bags of Aspen to lower the cleaning cost average. I don't want to buy frozen online, because shipping averages out to what I can buy live mice locally. Plus, I don't have the freezer space. Anyone have opinions on this?
