I think is fine... My normal is an mid-early 09 she has never missed a meal, She just broke 700g. She is not fat either, She would easily be 900g if I over fed her. She eats anything I give her.

I fed her every 4-5 days until she broke 500g, then I switched her to 7 days for my convinience. I think If I had left her in the 5 days schedule, she would easily be 900g.
