UPDATE 11:30 A.M.
You'll be happy to know that Walter Dean the Manx cat has been found by Wild Rumpus.
"WALTER IS BACK! We found him in a back stairwell that we had checked multiple times, but obviously even the biggest pumpkin of a cat can be sneaky and hide incredibly well," the bookstore said.
"Thank you to everyone for all of your efforts to help find him! It gave us so much encouragement to see how vast and loving our network is! We are grateful to have him back!"
If you've ever been to Wild Rumpus, you'll know it's as famous for its in-store menagerie as it is for its huge range of children's books.
It's with sad tidings therefore that we bring you the news that the bookstore is looking for help finding one of its cats – named Walter Dean.
The "pumpkin colored/shaped" Manx cat (ie. tailless) was last seen as the store at 2720 W. 43rd St., in Linden Hills, closed around 5 p.m. Monday.
"He is tailless, and without a collar, and does not have a microchip," the store wrote on Facebook.
The store suggests that he may have left the store on somebody's stroller, and those who visited on Monday are being asked to check them.
"He loves to steal stroller rides, and may have snuck out in one, so he could very well be in the neighborhood," it added, saying that Walter Dean "reacts to his name, and loves food."
Anyone with information should contact the store at 612-920-5005, or after hours, email firstname.lastname@example.org.
The tailless Manx cats, by the way, are so named because the breed is believed to have originated on the Isle of Man, located in the Irish Sea between England and Ireland.
Its tailless nature is the result of a genetic mutation, and it's the only cat bred to be tail-free.
