International Cat Day 2026

International Cat Day comes round once a year. Cats behave as though it is every day. Our International Cat Day t-shirts round up sixteen original illustrated cats, each drawn in a completely different art style and each entirely unbothered by your plans. Expect a tuxedo cat in neon vaporwave shades, a fantasy guardian defending the warm spot on the radiator, a pixel-art hero whose main quest is a nap, and an astronaut cat drifting past a ringed planet with zero cares. There are no borrowed logos, no licensed characters and no famous internet cats here, just original artwork and original punchlines. Made for rescue adopters, multi-cat households, and anyone who has been personally ignored by a small animal they feed twice a day. Every funny cat tee prints on heavy cotton with a unisex fit and art built to outlast the wash pile. Browse the full International Cat Day collection below.
