Did you solve it? Are you smarter than a cat?

The answer to today's moggie mystery

In my puzzle blog earlier today I set you the following question:

A straight corridor has 7 doors along one side. Behind one of the doors sits a cat. Your mission is to find the cat by opening the correct door. Each day you can open only one door. If the cat is there, you win. You are officially smarter than a cat. If the cat is not there, the door closes, and you must wait until the next day before you can open a door again.
