Sorry I can't go, I'm an indoor cat. Perfect cup to curl up on a cozy couch with and avoid people!  This is a handmade ceramic mug created by me in my New Jersey studio. This is a stoneware mug measuring 4 x 4. Interior is yellow. Kiln fired, lead free glazes. Holds 16 oz. Dishwasher and microwave safe. Funny gift for an introverted cat lover.
