Q. T. McWhiskers

Q.T. McWhiskers is an invention by Professor Farnsworth which is intended to be a cat shaped children's toy which when petted, shoots rainbows from its eyes and says meow. The rainbows emitted do not appear to be dangerous to humans. They are, though, powerful enough to light cigarettes if held close to the eye. However, Mom wanted to make it 8 feet tall and replace the rainbows with neutron lasers, which angered Professor Farnsworth, and he dumped her. Undeterred, Mom proceeded with her modifications and repurposed the disturbingly charming toys as intimidating and destructive weapons, specifically to support the Mother's Day Robot Rebellion.

Trivia
In *, the Professor told Mom that he didn't care if Q.T. Mcwhiskers was 1 foot, 8 feet, or 15 feet tall. However, when Mom told him about the sixteen feet tall version, Professor Farnsworth got outraged like he did so many years previously.
