Zeus and the Glass Smalti

I was trying to figure out why my cat Zeus was so interested in certain bowls of my mosaic glass smalti.  The top right one seemed particularly interesting.

I won't ever understand how cats think.  Especially this one, but I think I figured out this one.  It was close to dinner time, Sometimes he eats out of bowl and the smalti was pink.  I think he was hoping it was shrimp or something tasty.

Instead it's a tasty treat for someone else. I shipped out my spares to a friend who will give them a good home and turn them into lovely art.
