Q.T. McWhiskers was an invention created by Professor Farnsworth. It was intended to be a children's toy, and when it was petted, the toy would meow and shoot rainbows from its eyes. Mom changed the production model into a massive killbot that shot lasers from its eyes, causing Farnsworth to quit. It is later seen destroying New New York, proving Mom built the robots in spite of Farnsworth. Its rainbow eyes are hot enough to ignite a cigarette.
