I've never heard of a thirsty coaster, what is it made of? This could help with the puddle under the bowl but I think I'm going to have to live with the water splashes up the walls and furniture as he shakes what he doesn't want to drink off his paw. Dalla has big paws too, unusually wide although I don't think he's polydactyl. He's going to the vet tonight so let's hope I have better news on him than on Faline.
