Funny Cat gurgles when petted

My cat, “The Peefus,“ makes funny noises. UPDATE: While this video is going viral, I want new viewers to remember a few things: -Peef is fixed. She is therefore not “in heat.“ -She reacts this way when her back is scratched. Her back. That’s where she is being scratched. -She eats very high-quality, grain free food, supplemented with squirrels, chipmunks, snakes, and neighborhood children. -She is 18 years old this year. -This video is 3 years old.
