What will happen to cats if they don't get rid of insects?

If cats don't repel insects, there will be certain health risks. This is because cats carry various parasites, such as roundworms, tapeworms and hookworms. These parasites will be excreted through the feces of cats, and when other animals or humans come into contact with these feces, they may be infected with these parasites.

Parasitic infection can cause many symptoms, such as:

1. Dyspepsia: Cats infected with roundworms or other digestive system parasites may have symptoms such as vomiting and diarrhea.

2. Obesity: Ascaris parasitized in cats' intestines will absorb nutrients, which will make cats feel hungry and may lead to obesity.

3. Anemia: cats infected with blood parasites such as hookworm may have anemia symptoms.

4. Skin inflammation: parasites such as tiny tapeworms will parasitize under the skin of cats, causing itching, skin inflammation and other symptoms.

5. Infectious diseases: Some parasites can also spread some infectious diseases through fleas, fleas and other intermediate hosts, such as infectious anemia in cats.

Therefore, in order to protect the health of cats, it is recommended that cats regularly deworm once every six months or so. Prevention is better than cure. Insect repellent can not only protect the health of cats, but also reduce the risk of disease transmission and protect the health of humans and other animals.
