The Cat in the Hat starred in The Wubbulous World of Dr. Seuss. A Muppet version of the character created by Dr. Seuss in 1957, the Cat lives in a large playhouse, from which he observes goings on in the Wubbulous World through his Wubbuloscope. Though still speaking in rhyme, he is a sometimes more sedate character than his print counterpart, particularly in the second season. With the assistance of the Little Cats, he serves as mentor to his friend Terrence McBird and acts as gentle host to the home audience.
During the first season, the Cat acted primarily as host and narrator, but by the second season, he participated more actively in plots, usually in the frame stories with Terrence. Also in the second season, the Cat opened each show with a rhyming greeting to the audience: "I'm so glad that you're here, oh I like it a lot, it's just not as much fun to be here when you're not".
- Before The Wubbulous World of Dr. Seuss went on the air, The Cat in the Hat appeared at the 1996 Kids' Choice Awards.
- In 1998, the Cat, the Little Cats and Terrence McBird appeared in the Nick Jr. promo segment called "Ask The Cat" (where the Cat would answer questions from kids).
