Cats will have a pointed face, a triangle, and a particularly prominent mouth and nose before they send their cheeks. But after they finish their cheeks, the muscles on the lower side of their cheeks will obviously become bigger and look round, just like Garfield's double chin. Before and after waxing, the cat's face will be sharp and triangular, and its mouth and nose will be particularly prominent. After patting, the muscles on the lower side of the cheek will obviously become larger and look very round, just like Garfield's double chin.

Not all cats can have gills, such as civet cats and siamese cats, which are born with triangular faces. Genes determine that they can't be born with big round faces. Most cats with gills are male, but it doesn't mean that female cats can't grow gills, but it's more difficult, because in the case of more comfortable diet, environment and other aspects, the chances of male muscle growth will be higher.
