I'm feeding frozen/thawed, bought from a local reptile store. I prefer f/t because it is easier for me in that I don't have to go to the pet store every week, and I don't have any desire to breed my own right now. I also like buying them already killed so I don't have to do it (I could if I had to, but I don't like to if I can avoid it). I prefer dead prey over live prey because I think it's more humane to the prey (if killed properly in the first place, even though the snakes can be pretty efficient at their job) and safer for the snake (though it may not happen often, the potential risk of rodent injury to snake just isn't worth taking the chance, to me). My rosy boas took f/t from their first meal, and the ball pythons I just got were taking dead prey too, so works for me!
