She looks just about right to me!

I am assuming she is the only cat in the household? Just go by the amount it says they should have and then split that into two feedings. Probably a 1/4 C in the morning and then in the evening. When she finishes it don't let her have more till the next feeding time.

My other suggestion is this.....my Katiebug is a eat and puker...I put her on Royal Canin's food for Sensitive stomachs. It has cut down the amount of throwing up she does by more than half. And they really really like it. It also has 3 different shapes for finicky eaters and has really good quality ingredients. You can usually find it at most pet stores...our Petco has it. But that has helped her bulimic tendencies more than anything else I have ever tried.
