I'm currently going through the same with my Irian Jaya Carpet Python. He was started on f/t mice and I had to put him on live to get him to eat rats. Next step in my book is to start offering prekilled then frozen. I haven't ever offered him prekilled (yet) but that's usually a safe step to switching any snake to f/t.

I've also heard of giving the snake a live meal and follow it with a frozen. You'll also probably want to look at how you're offering the frozen food. I offer wet rats but you'll want the rat to look as alive as possible so try to keep it dry. Play with temps, some snakes like the food ridiculously hot, others prefer cooler food... 

I've had one go 18 months. If they are otherwise in perfect helath I'd starve her out, basically. She'll get hungry eventually.

I didn't know they could go 18 months without food. That's impressive. When I offer Frozen I have tried wiggling it, wet in warm water, warm but dry, the chicken broth method, braining, I even tried opening her mouth and putting the head but she won't eat it. I'm going to try a small prekilled meal followed by something else like you said. If that doesn't work I might attempt putting a pinky in her throat. Even though she she hasn't had a meal , she's still very active, climbing branches, and have only lost 5g in weight.

Yours is not an adult like "Cenobite's" was, though. I'd think that'd be too long for a juvie Carpet. Good you are tracking it's weight for future reference, though. 8 grams is minimal, I don't think there's reason to worry at this point, nor do I think you should put a pinky in her throat - that would be a cause of stress and could set you back. I would offer late at night, while the animal is perched, and if you can get your hands on a quail or chick to thaw the rat with, that may do the trick. Are you leaving the F/T prey in the cage overnight? 

I've found actual chicks to be WAY more effective than chicken broth. just as Sonja says, and you can cut a single chick into 7-8 pieces, put in a big mug/bowl or something with the frodent and cover with hot water, let it sit for a bit. 

and yeah, 8 grams isn't an issue. 80 g? maybe time to get nervous, and I also absolutley agree on the force/assist-feeding. no bueno.

I thaw a little different - I rinse the rodent, and then put the rodent and the chick or quail in a sealed ziploc and then thaw in the hot water to keep the scent stronger.

I'll try scenting them with chicks when I get a chance. She eats live rats just fine, is frozen she doesn't want to. And I have tried at night, in complete darkness, while she's moving, and nothing, she'll look at it then slither the opposite way. But I have a question, if she eats live rats just fine...how is scenting it with chick or quail gonna get her to eat frozen? 

I didn't pay attention to the age of the animal. My bad. 

Think of it as say, I don't really care for plain pretzels, and have no problem passing a bowl of them, but say they were chocolate covered ones, I'd be more apt to grab one.

I can also see it as, if you don't like my plain pretzels, eventually you'll be so hungry you'll love them lol
