Sorry for blowing up but I dont think people should look on craigslist for free food. It may have disease, could be someones pet or it could hurt your snake. Also if it refuses to eat rats again then what?

I'm not trying to be a ass and I'm sure I came across that way, but there are too many what if's here. I dont think it is worth it to save on food cost because it may backfire in his/her face
