We feed Yoda Royal Canin 28 dry food. We also cook him chicken (no additional flavor, just steamed chicken). When we leave him alone, we usually block off the kitchen area and he can roam around there. We leave a cushion, some clothing of ours, and we also leave on classical music. Generally, he just sleeps until he hears that we are home. Also, we leave out the dry food and water for him.
