I stick to the OHPW diet with fruits and veggies. that is the MAIN course.
I dont mess with that.
I give treats, avocado they love but very fattening.
mealworms, live and dried. yogurt drops.
I just ordered paradise pets fish sticks. 10% the calories of yogurt
and suppose to have lots of nutrients and good stuff.
others get chicken feet
I'm not sure about fish.
