Nope there is no scratches or dents. Hmm good point that it probably would have made a dent since it is only one paw print. It could be the wax stuck better in that area. Or maybe it could be the chupacabra. I don't know if you have heard about it but down here in the texas, mexico border there have been some sightings. The chupacabra means goat sucker in spanish. Hmm it is kinda cool to wonder. Thanks

IRescue452- If that happened to me then I would take random pictures of different places of my house to see if any ghostly images come up.
