Generally, cats are not afraid of thorns when eating fish. There are many barbs on the cat's tongue, and this special structure can shave most of the thorns, but it is recommended that owners remove the thorns first when feeding their cats fish, so as to prevent their cats from being stuck or scratched by the thorns.
Additionally, owners are advised to feed their cats cooked fish that has been steamed and cooked at high temperatures, and to pay attention to the amount of fish they are feeding in order to prevent their cats from contracting parasites and bacteria that could lead to illnesses, or indigestion due to eating too much of the fish.
Cats eating fish need to pick out the fish spines, especially some large fish spines, and need to help cats pick out the fish bones and fish spines, otherwise they will easily get stuck. When owners feed their cats fish, it is best to feed salmon and other fish with fewer barbs. Although the barbs on the cat's tongue can handle fish spines, there is still a chance that the cat will get stuck and the cat will act very uncomfortable.
When this happens, most cats are incapable of handling it on their own. If you see your own cat get stuck and vomit several times or uncomfortable, you need to pay attention to it, and then you need to go and take your cat to the hospital to check it out.
In addition to the fishbone will have the possibility of stuck, like chicken bones and so on, some of the finer small bones, if you do not pay attention to if it is also very easy to scratch the cat's throat, owners usually feed time to pay more attention to, try to avoid.
