Katilda is an adventure-seeking and imaginative cat with a rather tomboyish personality. However, the perky feline can also be rather clumsy at times, with her "hitting her head unconscious or tripping over things while rushing off" ways. Katilda may be a polite and playful girl, but she can sometimes get pretty sassy and sometimes downright cold.
Katilda is a yellow cat with brown hair under a lavender headband. The hair is tied up into two pigtails with lavender bows at the ends. She has rosy lips, rhombus-shaped eyes and a tiny black nose. She's at about Waffle's height (or maybe taller), and her torso makes up most of her height while her legs are rather stubby.
