A friend of mine had a theory about why cats stare at invisible things or talk to the air... They're visitors from another planet. They're FELIONS, sent here to spy on humanity and report back to the mother ship.

Houston, our male cat, is a spring with fur. That boy has a 4 foot vertical leap... up or down. In our house we have a cat condo that stand about 4 feet tall. It sits downstairs in the living room, with the loft above and slightly past it. The floor of the loft stands about 6 feet above the condo. One of Houston's favorite things is to leap off of the loft onto the condo. You'll be standing there and suddenly you'll hear a "THUMP" and Houston will magically appear, from nowhere, on top of the condo.

One day we had a dogsitter coming to walk the dogs while we were at work. Apparently Houston did his flying cat trick for the dogsitter. It about scared her pants off. She had no idea what the loud noise was and suddenly there was this cat staring at her at eye level.

Riley, the girl cat, knows that my time at the computer is her time to be petted. In the morning when I'm at the computer she sits on the desk and meows and pats me on the shoulder until I pet her. If I quit before she's ready she screeches and pats me again.
