Great picture and story. All 3 of my cats are indoor cats so I never have this problem. Pepper sometimes thinks that he wants to go out the front door, which opens up into a hallway, so he'll go running out and then get scared and run back in. There's a Chihuahua that lives down the hall. Pepper's at least 2-3 times bigger than it. One day when Pepper was bravely sitting in the hallway the Chihuahua came out and Pepper got so scared that he ran inside. I don't think I've ever seen him move that fast.
