She wasn't underfed that I was aware of. When i received her she was in excellent body condition, full and healthy looking and no "triangle" or thin look about her. I just weighed her today when i cleaned her cage and she's 1232 grams its just crazy.
Its nice to know that at lease SOMEONE else has had this happen (and im sure there are plenty of other people too, I just wanted to know about it).
Thank you for your response.
I think she got my cinny females growth genes. Shes well over a year and only 360.
