Jeanie, when Max and Teddy were eating different diets, I had to separate them with a baby gate until they were finished. Teddy always wanted to eat out of Max's bowl, and Max let him.
I hope Maggie will enjoy the baked treats and take greater interest in the veggies. It is hard to resist the sad eyes.
I also understand the difficulty of managing another human who is in charge of care.
Keeping Maggie in my prayers for the diet and med to bring normal BATs in a few months.
