I want to switch to f/t, but I'm not sure what to get. I was looking on Rodent Pro, and it seems you have to buy a bag of 50, so I want to make sure I get the right sized mice. Before I got Norbert, he was eating either hopper mice or small mice. The mouse I fed him was a fresh kill, the smallest mouse they had at the store. It was about a couple inches long. Norbert is 6 months old, 189 grams, I don't know how long he is. I'm guessing I should get Weanlings? I just don't know if I should get a bag of 50 small mice if my snake's going to grow and need bigger mice soon. Let me know what you think.
