feeder rats and mice

[ohh_kristina]

Does anyone know where I can buy some (small quantity!) small frozen rats/large frozen mice online? I don't want to have to buy 100 rats when the snake eating the rats will probably grow to need larger prey by the time I finish feeding all 100 rats. My cousin is giving me his ball python (he's about 3 feet and stocky ..feeding on small rats, as I mentioned before) and I want to try and start feeding him frozen rats. He's on live now, and has already been bitten numerous times by the rats. It's very sad. My cousin decided that the snake was getting too large for him (he's 10). Thank goodness he didn't buy a burmese!
I also have a very small (under 2 feet) BCI that I am feeding small mice to. I already have her on freshly killed, but would like to switch to frozen. Any help would be appreciated!
