Why don't cats get stuck in their throats when they eat fish?

In daily life, it is common that some animals such as cats and ducks can't get stuck when eating fish, while people often get stuck when eating fish. What is the reason?

This is because one after another

The front of the cat's tongue is like a rough file, with thousands of small backward protrusions, which are the nipples of the tongue, commonly known as barbs; Tongue papillae is actually composed of nail-like substances and has no taste function. It can help cats remove the meat from the bones of their prey, and cats eat politely. In this case, cats are generally less likely to eat prey that is easy to get stuck in their throats, such as fishbones.

Furthermore, the esophageal structure of cats is different from that of humans, and the whole esophageal wall of cats is long. There are muscles that are convenient for nausea, making it easy to spit out excess or inappropriate food. This is a convenient way for cats. Even if they are stuck, they will spit out the food in their stomachs until the fishbone is taken out.

This is why we often throw up all over the floor after eating fish.

Let's talk about ducks. Ducks don't get stuck eating fish. The traditional view is that duck's saliva digests fishbone. In fact, duck saliva, like human stomach acid, has the function of dissolving and softening bones, so ducks will not get stuck when eating fish.

This is why cats, ducks and other animals are not easy to get stuck in their throats when eating fish.
