Actually, that may not be a face of disgust. That cat is inducing the scent into their mucus ducts behind their 2 large top canines. They channel up into the nose, and unlike humans and dogs, cats are scentblind to anything airborn, and need to encorporate the chemicals into a fluid. It takes them a second of “mouth breathing” after smelling a thing to trigger the scent response in their brain. I had a cat that made the most disgusted face whenever we gave her wet food, but then she always burried her snout straight to the bottom of the tin.

That’s the face I’d make if someone shoved a spoon of Greek yogurt in my face too.
