Hey! I just bought my baby BP (piper) last Sunday. She had only ever been fed live prey before. I wanted to switch her to f/t because it bothers me to see their little bodies wiggle as they are being killed. I went to petsmart because I'm new at this and can't find any local feeder places around here in nc. I took Piper with me to use as a reference for what type of feeder to purchase. The "reptile expert" at petsmart convinced me to buy a pack of 6 frozen fuzzies (mice). I fed Piper one but she scarfed it down pretty quick and still seemed hungry so I gave her another and then another....lol I added up the grams for the fuzzies and total weight she consumed about 15-18 grams. I'm still waiting on my scale to be shipped to me so I don't know how much Piper weighs but I need to go ahead and purchase f/t feeders in bulk. I know she can handle (in grams) atleast 18. So does that mean I get her a small adult mouse? Or should I try for a little bigger? Like a rat pup? I know she needs to get on rats ASAP but I feel like for her first rat she would do better with one of the "pups". How big is too big? I know you are supposed to match it to the thickest part of their body but without a bunch of rats/mice in front of me I can't really determine that... Any suggestions? I don't want to over/under feed her. She is precious to me... Lol
