How funny! I once had a cat that would snag food from my plate and put it in his dish. It would be solid things like a bagel or cookie or toast. He would also help himself to cookies if I left a bag out on the counter. He would take chicken off the grill and run to put it in his dish! He lived to be 18, so it must not have hurt him. He also put toys in his water dish - often things that would absorb the liquid. How funny!
