I am new to this site as well.
I have a ball python that is about 1.5 years (according to the store) but I have only had him since Feb.
He too had an injury which now seems to have healed - there still is a bit of a scar but I think it should be gone in a shed or two - but he has also changed colour.
When we got him he was a beautiful yellowy brown and dark brown now it seems like he has lost his yellowy tinge.
Seems to be healty otherwise, eats well and very active.
I would like to have his colour back - any thoughts?
When I figure out how to post pics, I will.
