The fleas will die in about two days after the cat is dewormed. However, in order to avoid being infected with fleas again, the cat needs to be dewormed externally once a month. You should also pay attention to the hygiene of your home, clean and disinfect it regularly, and try not to take your cat outdoors, especially to places with a lot of mosquitoes, to avoid being infected with parasites.
Tip:
When performing external deworming on cats, the deworming medicine should be dropped on the back of the cat’s neck to prevent the cat from accidentally eating it and being poisoned.
