How often should cat external parasite prevention be done?

Cat external parasite prevention is recommended to be done monthly for prevention. It is usually advised to start external parasite prevention for cats around the age of two months to avoid poisoning due to insufficient weight for drug use. During the use of external parasite pesticides, the dosage should be strictly controlled according to the cat's weight, and the specific usage method should be followed closely by the doctor's advice. When deworming cats, it is also necessary to regularly disinfect and clean the living environment and items used by the cat, and keep the living environment dry.

Firstly, preventive external parasite control is recommended to be done for cats monthly. Usually, the external parasite control of cats is related to the season, with summer recommending monthly external parasite control and winter allowing for a longer interval of 2-3 months. In addition, the deworming frequency can be appropriately adjusted based on factors such as the cat's outdoor activities and living environment. If the cat often goes to forests, grasslands, or other places to play, or if the living environment is relatively messy and damp, the deworming frequency can be increased accordingly.

Secondly, since the common external parasites of cats have strong reproductive capabilities, it is recommended to perform external parasite control for cats monthly. For example, the common flea can lay about 50 flea eggs per day, and these eggs can develop into new fleas within 21 days. Moreover, the external parasites of cats are in their growth stage, which is invisible to the naked eye, so it is advised to regularly deworm the cat for prevention.

Lastly, cats usually begin external parasite control around the age of two months, but if the cat's weight is less than 1 kilogram at this time, it is not recommended to proceed with deworming temporarily to avoid poisoning after using external parasite pesticides. It is advised not to bathe the cat for three days before and after external parasite control, mainly because the external parasite pesticide works by spreading through the sebaceous glands to the whole body. Bathing will destroy the sebaceous gland layer, resulting in poor efficacy of the deworming drug.
