"Hello, Hello" is a song that the Cat in the Hat sings with the Little Cats and Little Cat Fleep about all the different ways of saying hello. As the Cat in the Hat sings about different ways to say hello, he points out some of the other characters that live around the playhouse and the way they say hello.

The song was featured in the Wubbulous World of Dr. Seuss episode "Talkin' with the Cat".
