I have a snake right at that size (200g) and I'm feeding her 1-2 rat fuzzies each feeding. I could probably get pups but I ordered 2 bags of fuzzies last time so I'm kind of trying to not waste them all together. I can't wait to get pups though to go to one rat per meal. I haven't seen a rat in my weaned pack that she could take though without me really worrying. If I had to do it I'd probably let her go a full week (I've been feeding her every 5-7 days) and then offer the smallest weaned I have. I really wish I could just feed those smaller snakes a fuzzy every 3-4 days though, that would be so much easier.
