Sylvester, who for the most part has always played the antagonist role, is featured playing the protagonist role in a couple of cartoons while having to deal with the canine duo of Spike the Bulldog and Chester the Terrier after being chased around. In 1952's "Tree for Two" by Friz Freleng, Sylvester is cornered in the back alley and this would result in Spike getting mauled by a black panther that had earlier escaped from a zoo without Spike and Chester knowing about it. In the 1954 film "Dr. Jerkyl's Hide", Sylvester pummels Spike (here called "Alfie") thanks to a potion that transforms him into a feline monster. Both times after Spike's ordeal, Sylvester would have the courage and confidence to confront Chester, only to be beaten up and tossed away by the little dog.
