Not that I have ever heard that said before. Because cats, and cat mugs, are like potato chips- almost impossible to stop at just one. This is a handmade ceramic travel mug created by me in my New Jersey studio. This is a stoneware tumbler measuring 6.25 in H x 3.5 in W x 3.5 in L with a black food grade plastic lid- a great eco friendly alternative to paper cups!
