In fact, cats have an estimated 45 to 200 million odor-sensitive cells in their noses, whereas humans only have 10 million odor-sensitive cells (known as "olfactory receptor neurons", or "ORNs"). [19] [20] [21] Cats also have a scent organ in the roof of their mouths called the vomeronasal (or Jacobson's) organ. When a cat wrinkles its muzzle ...

The high-frequency aspect of the purr may subtly exploit humans' sensitivity to these cries. Using sensory biases in communication between species provides cats with a productive means of improving the care that they receive. [19] Cats often purr when distressed or in pain, such as during the three stages of labor.
This causes the device to emit high frequency noise which is uncomfortable to the cats, and inaudible to most humans (although they can still experience unpleasant subjective effects and, potentially, shifts in the hearing threshold [1]). The devices are available in both battery and mains operated forms, the latter generally having a higher ...

It can be difficult to understand what emotion the cat is portraying with their ears, especially since their ears undergo the same pattern when the cat feels they are in danger/feeling ...
Cats are sensitive to pheromones such as 3-mercapto-3-methylbutan-1-ol, [81] which they use to communicate through urine spraying and marking with scent glands. [82] Many cats also respond strongly to plants that contain nepetalactone , especially catnip , as they can detect that substance at less than one part per billion. [ 83 ]
