I started my collection 3 years ago so the majority are between 2 - 3 years of age, with a recently acquired juvenile of about 5 mos., and a couple that were acquired as adults.&nbsp; MOST of mine eat f/t, with a couple that came to me eating live and have resisted making the change to f/t.<br>In my limited experience I have found that USUALLY youngsters eat better and more consistently than adults. There may be random circumstances, such as shipping, shedding, etc. that will put the young ones off for a bit, but for the most part, if temps, humidity and habitat requirements are met, they might go off for a couple weeks to a month, but then get themselves on track.<br>THIS year however,&nbsp; starting in late fall/early winter, almost all of my adults are off. Some have only had a couple meals since early November and even my most dependable eaters are skipping meals.&nbsp; Since my husbandry hasn't changed, I'm assuming it's hormonal , esp. as a few of them are JUST starting to be a bit more animated and show some of their old interest when I've got the hair dryer working on warming up f/t.&nbsp; &nbsp;<br>Very generally, I find that offering live will often prompt one that's off their food to strike/wrap, and feed.&nbsp; The downside of that though, is I would prefer NOT to transition those that previously took f/t to feed on live only.&nbsp; I no longer worry the same way I used to, I have reached the point in which, if the snake seems to be in good condition and refuses food when offered, I just wait 10 - 14 days and try again.&nbsp; &nbsp;I look for them to be "cruising" in their bins, as that's often a sign that they're hunting, so laying with their head out of their hide is an indicator that they might be at least THINKING about hunting.&nbsp;<br>It's been my experience that if they act like they're afraid of the prey they probably aren't going to take it.&nbsp; If they show NO interest, no tongue flicking at the prey etc., they probably aren't going to take it. If I'm not sure, I usually heat up one less than I think I need so am not discarding rats all the time.&nbsp;<br>Hang in there, if your conditions are right, and if your snake was eating well before, it's probably just taking a break.&nbsp; Easier said than done, but TRY not to worry, ball pythons can be frustrating in the feeding department, but will usually get around to eating whey THEY feel like it.
