Edward Gorey #18

The Edward Gorey postcard mail-a-thon continues with card #18 from the 2011 postcard collection book. This addition to the Edward Gorey postcard collection doesn't say anything about the image on the card, only that it was a drawing by Edward Gorey.

To me, it looks like a cat is wearing a mask and walking dangerously close to a well or a pool. Possibly the cat is dancing or drunk. What does it mean? I have no idea. Do you?
