The "Kitties" set features cute, lively, and slightly cheeky cats in various costumes: from boxer to warrior, with expressions as if they're ready for an adventure. In one frame, a ginger cat raises its paw, as if giving a signal; in another, a cat with a dirty face and red spots in a blue sweater, as if just out of battle. They're perfect for funny, friendly, or even slightly cheeky messages.
