Bungle, the Glass Cat is a character in the Oz books of L. Frank Baum.

The magician Dr. Pipt tests his Powder of Life by animating an ornamental glass cat figurine, for the specific purpose of catching mice for his wife Margolotte.

The cat "is so determined not to show emotion that when implored to bring help she sets off very slowly and runs only when out of sight.

After her adventures in that book with Ojo the Lucky and the Patchwork Girl, the Cat ended up being a pet of Princess Ozma in the Emerald City.

Unlike her book counterpart, Bungle acts like a real cat as she chases a mouse around Emerald City.
