Grumpy Cat Birthday コーヒーマグカップ

Make them laugh out loud on their birthday with this funny cat-themed birthday mug. Featuring an unimpressed cartoon kitty in a party hat and the caption “I came for the cake,” this design brings the perfect amount of sarcasm to a birthday morning coffee or tea routine. It’s ideal for cat lovers, introverts, or anyone who enjoys a little dry humor. This sturdy ceramic mug is both microwave and dishwasher safe, making it a practical and playful gift. Whether you're shopping for a coworker, friend, or sibling, this mug adds a touch of personality and a guaranteed chuckle. I designed this with clean lines and soft colors to let the humor shine through, and to keep it neutral enough for everyday use after the candles are blown out.
