Tony left his lunch bag on the coffee table. The cat had knocked it down earlier in the day, but I hadn't picked it up yet. Porter must have been nosing around and found a little something that had been left over.
This is a Granny Smith apple. Neither Lexi or Hudson had any interest in it, so for once in his life, Porter got a treat completely to himself. After he had smashed it sufficiently, I took it away, removed the core and gave it back. He wolfed it down and is now happily lazing about.
