belated Happy Birthday to someone whose household resembles this rather a lot:

Pictures with several animals, cats particularly, all sitting still and looking in the same direction have always amazed me. It's possible to get dogs to do this, because dogs are nearly always interested in humans and, if they're at all socialized, can usually be made to sit and watch. Cats, on the other hand, do whatever they damn well want to.
Since the person this is for trains animals, it just seemed especially appropriate.
