This card features three cartoon cats sitting side by side against a deep green background sprinkled with small white shamrocks ☘️. A black cat with bright yellow eyes sits on the left, a white cat with lime-green spots rests in the middle, and an orange tabby sits on the right, all facing forward with open smiles and rosy cheeks that feel like shared inside jokes between friends 💚. The colors are flat and solid with no shading, giving the scene a crisp, graphic look. Above the cats, the word “HAPPY” curves in an arc near the top, drawing your eye down toward their faces. Along the bottom, the message reads “ST. CATTY’S DAY BROTHER IN LAW,” stretching across the lower area like a banner. The lettering is white with a thin orange outline that ties neatly to the orange tabby’s fur. The trio is centered in a straight horizontal row, with the shamrocks scattered evenly around them on the emerald field.
