Last night I was down stairs watching TV and out of the corner of my eye I saw a black form move across the doorway at the top of the stairs!! I thought it was Popsie because it was low to the ground and he's black and white but I went upstairs to look and he wasn't around. He was on the upper floor sleeping.(I have a tri-level and I saw the shadow on the middle floor) I'm sure it was just a trick of vision but it was still creepy.
