I know this has been asked some years ago, but my piggy makes a horrible mush mess with his pellet food. It seems that he takes pellets into his mouth, fills his mouth with water, and I don't know....but there's mush mess all over the bottom of his cage making it nasty. Plus. his chin and chest are soaked in water from the excessive drinking. Today I'm trying to withhold pellet food in order to have a more sanitary environment. But he's wheeking, because he wants his pellets. Can anyone tell me why he's doing this, and is there a way too stop the mess?
