I don't have an answer for you, although I feed June about 30% protein. My vet has told me he is very healthy and a good weight for his size. He weighs 5.5 lbs and I feed him 3/4 of a cup a day (1/4 cup 3x a day). Are you sure 1/2 a cup per day is enough for Junebug, given that he's 6-7lbs? Or am I just overfeeding my guy?
Our babies have similar names by the way
We call June Junebug sometimes.
