Many people think that cats are born to love to eat fish. In fact, domestic cats are now evolved from grassland cats and desert cats. It is difficult to find water sources in the environment of cats' ancestors. It can be seen that cats' ancestors do not eat fish. It was not until cats enter human society that fish rich in protein and taurine are favored by domestic cats. In addition, in the cat's concept, fishy food is fresh, and the fishy smell of fish also satisfy the cat's sense of smell. It is wrong to say that cats are born to love fish.

Do cats love to eat fish in nature? As we all know, fish have low fat content, and the main nutritional needs and energy sources of adult cats come from fat. If fish are used as the staple food of cats, it will cause cats to have malnutrition. In addition, fish are divided into freshwater fish and seawater fish. However, freshwater fish have many thorns. Many parents are more willing to choose to feed their cats with seawater fish with more meat and no small thorns. Some parents even feel proud of this. They don’t know that seawater fish are very harmful to cats. First, the large amount of magnesium salt contained in seawater fish will form stones in the cat’s urethra, causing cats’ urinary tract diseases and even kidney disease; secondly, seawater fish contain a large amount of thiamine enzyme, which can decompose thiamine in food and body. If a cat uses seawater fish as its staple food for a long time, it can cause vitamin deficiency in the cat, causing cervical spine pain and inability to lift the neck. Therefore, parents should establish a correct feeding concept and not judge cats based on human concepts.

How can cats eat fish to be healthy?

First: Fish cannot be fed as cats' staple food, but they can be eaten 3 or 4 times a week in the form of complementary food or rewards.

Second: When choosing fish, it is best to choose freshwater fish with fewer fish bones. If there are many fish bones, it is best to carefully pick the fish bones before feeding to avoid damaging the cat's mouth, throat and esophagus.

Third: The fish head, gills, and internal organs must be removed. Because rivers or lakes are more or less polluted, such as heavy metal pollution, pesticide pollution, etc., these pollutants will remain on the fish's head and gills. Once the cat eats it, it will also have a certain impact on the cat's body, so the fish must be cleaned.

Fourth: Boil or steam in water, do not add any ingredients, it is the healthiest way to make fish for cats. Be careful to cook the fish. In addition to causing parasite problems to the cat, raw fish will also produce an enzyme to destroy vitamin B1. Cats lack of vitamin B1 may cause spasms, heart disease, and intermittent shock.

Fifth: It is best not to eat fish or bibimbap for cats with gastrointestinal sensitivity. Parents can buy targeted formula cat food for cats, of course it is best to ask the pet doctor.
