Ingredients & Directions:
Drain liquid from tuna packed in spring water. Freeze liquid in small ice cube trays (cocktail ice cube trays work nicely, as well as little square pill-boxes available at most drug stores - only fill these half full). Give no more than 2 cubes at 1 time as a treat. Reuse your can of drained tuna by placing in it an airtight container and covering with filtered water overnight for a second batch of tuna-pop water.
