When I first got Mochi, she was a mere 445g. The vet said she would like to see her hit at least 500g, and tonight's weigh in came in at 503!!! Wooooo!!!
Mostly through her pellets and hay. She didn't eat a whole lot when I first got her, but she eats a lot more now.
A couple times a week, I give her a supplement consisting of oats, oat groats, barely flakes, crushed cuttle bone (for calcium) and some other stuff that I can't remember off of the top of my head.
