This is a square ant free bowl for dogs and cats. This ant free bowl is suitable for water or food. Ant free bowls have a moat around the main section that you fill with water and this moat will stop ants from getting into the food. These are made of plastic and measure 8 1/2" x 8 1/2" in total while the main food section measures 6" x 6". The best use for this is with cat food or dog food but they can easily be used as a water dish.
