No, I dont belive so. I have had him for about a year, with no idea how old he is, i would peg him at maybe 3 but give or take a year or two. They guy told me he was one when I bought him but some guy at a petstore said he looked older.

I don't have a scale, but I have seen bloated and overweight pythons, and in my opinion, he looks more skinny then fat.
