Dampen noisy dog metal food bowls Dishwasher-friendly solution

I used some sugru to put feet on our metal dog bowls because our six dogs would make a right din when they were eating. 

I showed these to my brother when I was raving about sugru and he seemed nonplussed.  "Could you not just have used rubber feet?", he asked.  "I could........but rubber feet can't be put in the dishwasher."  "Ahhhh," he says as the penny drops, "that's brilliant!" - Cian, Ireland
