Proto-Sylvester (simply known as: Prototype-Sylvester) is a character from the Looney Tunes and Merrie Melodies series. Although its appearance varies, it is commonly seen with black and white fur (similar to its official successor Sylvester). In The Cagey Canary, a Cat tries to catch a Canary, but he is stopped by Granny and she threatens to throw him out in the rain. After many re-tricks, he fails. Finally the Cat is out in the rain with the Canary. This is the only cartoon where proto-Sylvester has brown fur instead of black and white fur.
