Too much to eat?

Yeah I agree that jumbo rats may be a bit too large. You should post a pic of your big boy and of the jumbo rats your giving him and we should be able to help you better with feeding him a more appropriate size feeder. My biggest female girl gets a medium rat every week and she's long and nicely rounded but not fat, she's a strong muscle. I've never heard of anyone feeding their ball pythons anything bigger than a medium rat.

My big girl gets large rats , but I agree with the pictures suggestion, jumbo rats at one place might be another's large.
