As long as the already mentioned concerns and conditions are met, I don't see anything wrong with it at all. In fact, a lot people already do this. So many in fact, that even though I don't see anything wrong with it, craigslist users seem to hate it with a passion. "flippers" as they call them, are for some reason a hated group of people. If someone gets their animal on craigslist, then sells it later at a higher price, people get all kinds of bent out of shape. Seems like once you get flagged as a "flipper" nobody wants to let you have their animals.

I guess people are just sore about not getting more money for their animals, and then to have someone turn around and sell at a higher price, just ticks them off. I don't know. Personally I wouldn't mind if someone flipped an animal I sold to them, but apparently a lot of people do mind and so "flipping" , especially on craigslist, is generally highly frowned upon.
