I was reading a book that i got a while back called the ball python manual by the Barkers and some vet guy that i cant remember how to spell his name but it began with a v. :D anyway it said that obesity in ball pythons can shorten their lives and is not good for them. i was thinking about when i breed them and have them in racks and not alot of room to move and feeding them alot to grow is this a problem? i mean all the big breeders out their like Adam and such.
