I feed Toto a "raw" food from The Honest Kitchen ... twice daily. I give her ample time to eat it and what's left gets tossed. She soon learned that she eats while it's fresh or at the next feeding!

She knows what time her meals are and "reminds" me if it's not on time. She also gets a small healthy snack around lunchtime [yogurt, cottage cheese, etc.] and she is as healthy as she can be!
