Details
The Wonder Cat birthday card brings an immediate smile to anyone who loves a mix of superheroes and cats. The hand-drawn black cat on the front feels full of character. It wears a small Wonder Woman–style tiara that gives the illustration a bright, playful edge. Above it, the line “Have a Wonder-Ful Birthday” adds a fun twist that feels warm and light-hearted.
Inside, the card is completely blank, which makes it easy to tailor your message. You might want to write something sentimental for a close friend or keep things cheerful and simple for a family member. Maybe you just want a friendly birthday wish for a colleague. Whatever the message, the space inside helps it feel personal and genuine.
Each card is printed matt on museum-grade stock, so it feels lovely in the hand. We use non-toxic inks and keep the size to a neat 7×5 inches. Every card comes with a clean white envelope and is wrapped in a clear sleeve to keep it safe. We also send everything free (if you are UK based) via Royal Mail 2nd Class, so you can rely on it arriving without any fuss.
If you hit a last-minute birthday rush, we can step in and help. We’ll write your message inside and post the card straight to the recipient. Just pop your wording into the message box at checkout. It’s a simple option that saves time when life gets busy. With thoughtful details and a touch of fun, the Wonder Cat birthday card makes any birthday feel a little more special.
