With my experience mind you I’ve only been keeping for 4 years but now have an established 6 ball pythons and feeding regularly. Smaller is better for males, least mine...my females don’t care cause there bigger. But I never move to feed, causes more stress for them and possibility for regurgitation. And when first getting them I wait a week or two before trying to feed..also I’m praying that it was a miss type that you fed a 500gram rat lol 10-15 % of body weight or thickest portion of body size for food is how I have typically fed.
