When cats still have fleas after deworming, they need continuous external deworming. Because if the cat is already infected with fleas, it is generally not possible to completely kill them with one deworming. It is recommended to use deworming drugs continuously for 2-3 weeks, and then once a month in the future. At the same time, the environment must be cleaned and dewormed, because flea eggs can easily pollute the environment, and after hatching into fleas, there is a possibility of re-infecting cats. It is recommended to consult a pet doctor if necessary.

Precautions for cat anthelmintics:

1. The dosage of cat anthelmintics. Anthelmintic drugs are toxic, so you must feed them according to the instructions on the instructions, especially for domestic anthelmintic drugs. You must weigh the cat before using the drug, and calculate the dosage based on the weight. Sometimes there will be a lot of medicine left. If you feel it is a waste, you can feed it to stray cats.

2. Cats should be dewormed regularly, about once a month. Cats are the final host of many parasites. Depending on the type of parasite, the growth cycle may be half a month, or even as short as a week, so deworming once a month is absolutely necessary.

3. Pay attention to the cat’s mental state after deworming. After deworming, some cats with weak stomachs and poor physical constitution will have symptoms such as vomiting, lack of energy and even fever. Generally, these symptoms will get better in 1 to 2 days. If this situation persists for several days, it is best to go to the hospital for treatment. Consult a doctor.
