I tried to find a tree where the boys could dig holes and explore. They usually get hopelessly tangled within minutes. The girls seem to understand that they can untangle themselves. Or, they patiently wait for me to untangle them. The boys do not have a patient bone in their hides! They also spent very little time digging, the cat sitting on the railing on the deck had them mesmerized!
This cat loves to live with danger!
