Anyone who grew up reading Dr. Seuss will be thrilled with the news that a long-lost manuscript has been found, titled What Pet Should I Get?—and is set to be published later this year.

Ted Geisel, better known as Dr. Seuss, died in 1991, but his widow came across the material for the book in an old box and handed it over to Geisel’s long-time publisher Random House.

Word is What Pet Should I Get? was written somewhere between 1958-1962 and features the same brother-sister duo from Dr. Seuss’ One Fish Two Fish Red Fish Blue Fish—who are picking out a new family pet.

“What will it be? A fish? You wish. A rat? Not that! A lizard? Those are for wizards!”

This is said to be the first Dr. Seuss book to be released in 25 years and there are rumours that there are two more books to follow.

Thankfully we won’t have to wait too long to find out what pet they get. Dr. Seuss’ What Pet Should I Get? Will be released July 28th, 2015.
