Where is cat in the hat available?

Excuse me, could you please elaborate on the availability of "The Cat in the Hat" by Dr. Seuss? I'm wondering if this beloved children's book is still in circulation and where one might find a copy. Is it readily accessible at local libraries, bookstores, or perhaps through online retailers? I'm particularly interested in acquiring a physical copy, but I'm also open to digital options if they exist. Thank you for your assistance in this matter.
