NO CAT DOOR REQUIRED . . .
The steps up to the apartment were at the back of the building. I set the messenger bag down on the floor of the covered porch at the top of the stairs. Herc popped his head out and looked around. “Not a sound,” I warned. “Not a meow, not a rumble, not even a burp. Rebecca will be here any minute.”
I bent down to close the top of the bag. He jumped out, looked right and left and then disappeared through the door before I could grab him.
Yes, through the closed door.
My heart stopped. I dropped down into a crouch. Hercules was definitely gone, gone through a thick, solid door. That was the other thing about him that I couldn’t tell anyone. He could pass through any solid object—doors, six-inch-thick walls, concrete foundations.
I didn’t have a clue how he did it. In fact, the first time I’d seen him walk nonchalantly through an inch-and-a-half-thick wooden door at the library, I thought I was having hallucinations or even a stroke. Because cats can’t walk through doors or walls . . . can they?
