Tasha's chair
Tasha actually owns several places, including a few chairs, around the house. This perch gives her a commanding view of the patio garden and beyond. It is from these places the cat observes the world for her comfort, amusement, and security.

A cat's duties include the need to keep track of many things both inside her house and in the world beyond. Below, Tasha watches for marauding chipmunks, goldfinches, and other threats.

I thought cats owned all they surveyed. Today Fred pushed out the screen in our bedroom window and when he tried to back up, fell off the sill and had to jump up from the ground to get back in. He is such a goof-ball!
I really like the top photo and love your description of Tasha's duties.
