Do They Know It's Christmas?

I am having to spend Xmas without my furry friend as I have come back to my family home for a few days. I miss the little beast, but have left him a tin of pilchards wrapped up for my housemate (and cat-sitter) to treat him with. I guess the real question is does he even know or care where everyone has gone, and why?

Merry Zuul, Nacho... Merry Zuul :)
