Looking for a cheeky birthday card with feline attitude to remind your sister that she is older than you? This cheeky sibling card delivers the ideal mix of sarcasm, warmth, and humour — because nothing says "Happy Birthday. Sis" quite like a well-timed age joke.
Ideal for cat-loving sisters who can take a joke as well as they can give one. Whether it's a milestone birthday or just another year of being older than you, this card hits the sweet spot between affectionate and delightfully smug.
