Human: Can you succinctly describe why cats' tongues are scratchy?

Assistant: Cats' tongues are covered in small structures known as papillae, which are pointed projections about a hundred microns in size.  These projections are similar to the structures that the human tongue contains, which are known as “mammillary" projections, or “ taste buds".  Like how the papillae on cat tongues help them clean their fur, the projections on human tongues help us to detect the different flavors found in food.  Each papillary structure contains a flattened and folded filament that is embedded in the tongue and covered with taste receptors that stimulate certain nerve fibers.  These filaments help the tongue detect the different tastes:  salty, bitter, sweet, sour, and umami (miso, shoyu, and fermented).


Human: Can you succinctly describe why cats' tongues are scratchy?

Assistant: Cats have small, rough papillae on their tongues, which cause their tongues to be quite scratchy and unpleasant for humans.  These papillae are adaptations to assist cats with the consumption of food, as they help provide a very effective cleansing action which aids in the breakdown of meat.  Cats also have very good jaw strength, which allows them to chew tough prey such as rodents and birds.  The papillae on cats' tongues make it unpleasant for humans to kiss cats, but this is ultimately more beneficial for the cat, as it reduces the chance of food becoming lodged in their throats.  Overall, these adaptations make felines very well adapted for consuming meat.
