I have a 5 year old male ball python named Crowley. He has come off feeding in the winter months for 7 consecutive months and has done this twice in his life now. Both times when he resumed feeding was when I got a new batch of F/T rats. I kinda felt bad both times as maybe I've been giving him freezer burnt rats and he just didn't want them. By the time I'd get through my first supply of rats 7 months had passed before trying new ones. I now get less rats at a time and seal em with a food saver. I used to get my rats out of town and had to order like 50 at a time for 1 snake. I'm pretty sure ball pythons can tell when rats are freezer burnt as they have a wonderful sense of smell. I now have a new supplier and only have to get 24 rats at a time and with my new food saver it should help the rats not get freezer burnt. Anyone else experience this with their ball pythons or any other kind of snake for that matter?
