The Cat In The Hat has nothing on these cats and kittens in adorable little hats. With all due respect to Dr. Seuss, of course. Let these hatted cuties brighten your day!
(A word of caution: some cats don't like to have their heads, especially their ears, covered, while other cats don't mind it! Pay close attention to your cat's body language and never put a hat on a cat who seems stressed out about it.)
