I have read a lot of guides and have been told by various people about the process of switching from Live to F/T. My baby ball python successfully ate 5 times every Sunday and they were Mouse Hoppers. I tried to feed him F/T today and he seemed a bit interested at first, never struck but hissed a little (first time I heard him hiss lol). I had it warmed to just around 98 or 99 degrees and only warmed it after it thawed for about 30+ mins. My BP weighs around 100 grams and was advised to feed him Rat Pup, which I got from a local pet store. So, I am not upset he didn't feed and know it can take some patience. My main question is whether the rat pup was too big, I forgot to weigh it but it was likely around 20 - 25 grams. And, now that this was unsuccessful, do I try again tomorrow or just wait until next Sunday ad that is his normal feeding day? Or, do I go back to live again and try F/T later? Thanks for any advice.
