Last weekend, while cleaning out a drawer, we came across an old film container. Sensing an opportunity to keep Max busy for a few minutes, she watched my put a walnut piece in and close it up. She immediately got to work trying to remove the cover:The container was a bit too deep for her to extract the nut:
This kept her attention for so long that she had to take a short break to preen herself, making sure to hold tight to the container:
After a few minutes of this, she accidentally dropped the nut on the ground and subsequently threw the container on the ground. I picked the nut off of the floor and gave it to her to eat.
