Yeah my girl's only around 24in. It is amazing how fast they grow though
I don't think all ball pythons have to be super chubby. Every ball is different and mine's always seemed a little on the thin side as well. I think as long as they keep a nice rounded shape instead of looking triangular or sickly then they're fine.
It is hard when they're in that in between size where mice are too small and rats are too big. I would try feeding two mice until she can get a rat down easy![]()
