I fed my girl a fuzzy rat every 3 days until 500g. Then a weaned/small rat once a week until 1000g. Now she gets a large small or small medium rat every 2 weeks. She went from a 90g worm to a 1000g destroyer in just over a year. Remember, pythons are much more stretchy than boas and can take bigger meals. My BP gal ate stuff that made me worried in the past where when she was done, it looked like she ate a football but she just rolled into her warm hide and I didn't see her for a couple days haha. I heard if you feed them too often or too big of meals though that it can put them into fast mode. Now I have no idea as my girl hasn't eaten since Oct or Nov so maybe there is some truth to it haha.
