Ball python growth rate?

Well, turns out I missread my scale, he is a little over 300 grams:bow: He just pooped too, I looked at it just now and then looked at the 250 mark( this isnt a digital scale) and then his weight, and he was a whole notch above it( 50 grams) yay i guess!

I was told that my python's first birthday was this month. My vet even sent a e-card (Ark Pet Hospital in MN). So cool. Anyway My guy is a little over 2 feet long. Pretty sure the store I got him from mixed up the dates. I'm thinking he's 2 by now. BTW, I love the store, I go there all the time for supplies.
