Today (Sunday morning) is feeding day for Rufus.
I won't be able to play with him for 2 or 3 days after, so I always take a few minutes to interact with him prior to feeding. In the first 2 pics, he just thinks it's "Play Time" and we are doing what we normally do.
In the 3rd pic I place him in the Feeding Container, and immediately "He Knows he's about to eat" and he starts hunting.
