I was cooking a while ago and my old boy sat there licking his lips for a bit of chicken and I gave him a small slice. Then he did the same as I was cutting up a lemon. He kept creeping a little closer, always smacking his lips so I decided to give him the benefit of the doubt as I recently discovered he liked grapes. I sliced a piece and showed it to him. He sniffed it and disappeared like a rat up a drain pipe. He did not return to the kitchen again all afternoon.
