Art lover?

When we sit down to watch TV, Loki has decided that his spot is on top of my ammonite mosaic. He obviously appreciates art (as I'm sure it can't be very comfy) and the very, very many hours it took me to make (I made the concrete base over a wire form, then mosaiced it, for an exhibition a few years ago. It has a real ammonite fossil in the centre). He also likes to chew on the crystals (dug out of our own garden), which can't be good for his teeth!
