Happiest of Birthdays Grumpy Cat

A delightfully tongue-in-cheek birthday greeting featuring a grumpy white cat wearing a striped party hat and a bright bow tie. The illustration pairs bold, playful typography - reading "Wishing you the happiest of birthdays" - with a vivid lime-green background, creating a striking and contemporary look. The cat's unimpressed expression gives the design a dry, humorous edge that will appeal to anyone with a fondness for feline antics or sarcastic humour.

This design is ideal for sending to friends, colleagues or family members who appreciate witty, light-hearted messages rather than overly sentimental notes. The clean, modern artwork and confident use of colour make it versatile enough for a wide range of recipients, especially cat lovers and those who enjoy a cheeky twist on traditional birthday greetings.
