I'm glad you increased. Looks like Mauer was seeing as much green as you held the dose longer - one of the reasons TR says to increase the dose after a period of time.
Interesting discussion of feeding and amounts needed. Neko was in the 6.5-6.7 kg range (part Maine Coon plus acromegaly so bigger). I thought she could lose a little. Her vet didn't want her to go much lower. I fed raw food. When I fed manufactured raw, I got the calories from the pet food manufacturer. They have a calculator on their website - I selected the "lazy/inactive adult" category.

For Mauer's ideal weight, the number of calories is 224 and weight of raw is 149 grams per their calculator. However, different proteins have different calorie values. And even within meats there is differences. For example chicken thigh is fattier and higher calorie than chicken breast. I usually fed about 125 grams per day, mostly because that's the size package they came in. And modified feeding based on weekly weigh ins.
