Ronald is Nature Cat's next-door neighbor and arch-enemy. He may be lazy, but is always up for some friendly competition, even if it’s against Nature Cat. He likes to lounge in his hammock drinking lemonade or spend the afternoon at the groomers. He is also a DJ and spins at the neighborhood parties and events. He is voiced by Kenan Thompson.
Ronald is an obese light purple cat with a pink underside, and an oversized nose, and purple stripes on his back.
