Furrball is a character in Tiny Toon Adventures. He is a homeless blue cat with a bite in one ear and a bandage on his tail (although he does attend Acme Looniversity). He hardly ever wears any clothes and normally lives in a box in the street (though sometimes, he lives in Elmyra's house, and at one point, he lived with Mary Melody). He is less anthropomorphic in nature than all other animal characters and seldom speaks. His hero and favorite mentor is Sylvester. Sometimes, he can be antagonistic, as he tries to eat Sweetie Bird and L'il Sneezer, but he is also a good friend to the other animals.
He was voiced by veteran voice actor Frank Welker.
