I have trouble with the drink, not the ice cubes. My Smeiko loves carbonated drinks. It's better in a cup from McDonalds with a straw in it. No cup is safe in our house. My husband and I always seem to forget too. We are minding our on business and then all of a sudden we hear. Thunk! Splash! There goes Coke all over our carpet. First he likes to watch the bubbles rise to the top. Then he wants to catch them. I love him to pieces though.
