Sylvester J. Pussycat Sr. is a fictional character, an anthropomorphic cat in the Looney Tunes and Merrie Melodies series of cartoons. Most of his appearances have him often chasing Tweety Bird, Speedy Gonzales, or Hippety Hopper. He appeared in 103 cartoons in the golden age of American animation, lagging only behind superstars Bugs Bunny, Porky Pig, and Daffy Duck. Three of his cartoons won Academy Awards, the most for any starring a Looney Tunes character: they are Tweetie Pie, Speedy Gonzales, and Birds Anonymous.

A bicolor cat is a cat with white fur combined with fur of some other color, for example solid black, tabby, or colorpointed. There are various patterns of bicolor cat. These range from the Van-patterned through to solid color with a throat locket or medallion. Bicolor coats are found in many cat breeds, as well as being common in domestic longhair and domestic shorthair cats.
