You can re-freeze prey once. After that its garbage. Also trying to feed 6 times in 3 weeks is part of the problem. They can go off feed for months and you never keep offering food every few days or refusing becomes habit forming. When they refuse you try again in 2 weeks. If it happens again they are probably off. Check your temps also and make sure your dialed in. This is the time of year a healthy snake can go off for 2/4/6 months. Mine was off for 8 months last winter only loosing 15 grams.
