While The Cat in the Hat was able to have an interactive read-along based off his own story by Living Books, he would also show up as an Easter egg in the other 2 interactive read-alongs of Dr. Seuss books. In Dr. Seuss's ABC, he will appear if you click on one of the C's on the Letter C page. In Green Eggs and Ham, he will jump out of the box featured on page 17 when clicking on it.

In the game's Alphabet Sing-along, there's an Easter egg that'll occur by clicking the letters S-E-C-R-E-T in that order, right after Izzy and Ichabod sing the alphabet song. Doing so will make a man in a purple sweater appear and sing "A B C D E F G- whoops, Sorry.".
