food every 4.5 days is a lot for any size ball python, unless the prey items were really small. they seemed to have gone up in size a lot in 3 months though, so i wouldnt think thats the case.
well it is possible that he fed several rodents during one feeding, most likely this would not be a baby, but i agree, if it's one rodent per feeding every 4.5 days IS alot
