The most worrisome parasitic disease in cats should be Toxoplasma gondii. In addition, there are many more that we are not familiar with. We have no way to kill parasites, so the main method to prevent cats from being infected with parasites is , is to cut off the infection channels of parasites. ​​​​​​

We often say that diseases enter through the mouth, and the same is true for cats. The parasitic diseases that cats suffer from mainly include internal and external parasites. In addition to the mouth, contact, skin infection, placental infection, etc. are also the main ways of parasite transmission.

Cats have swallowed drinking water or food containing infectious eggs and larvae through their diet, or they have eaten transfer hosts with larvae, such as cockroaches. It will cause healthy cats to be infected with parasitic diseases, which is what we often say is that the disease enters through the mouth.

Contact infection mainly occurs when healthy cats have close contact with cats infected with parasites, and the parasites are transferred to healthy cats. For example. Lice, fleas, mites, etc. can all be spread through contact between cats.

Cat’s skin is also one of the main channels for parasite infection. For example, hookworm larvae can directly penetrate the cat's skin through the infective larvae, burrow into the cat's body, and metamorphose to the parasitic site to parasitize, thereby endangering the normal work of the cat's body organs and endangering the cat's health.

In addition to the above, such as roundworms and hookworms, if there are parasites in the mother cat's body, the larvae can infect the fetus through the placenta, causing the young cat to be infected with parasitic diseases; such as Toxoplasma, it may also be transmitted to the lactating mother through the milk Stage 1 kittens; heartworm larvae, for example, can be transmitted through intermediate host mosquitoes.

Moreover, some parasites can survive in the external environment for a period of time, such as mites. If items infected with mites are used directly by cats, they may be infected with mite parasitic diseases. This method of spreading parasites is called indirect contact infection.
