If your cat has fleas, here are some ways to get rid of them:
First, you can use a dedicated flea-repellent drop, spray, or shampoo, following the instructions, and make sure your cat doesn't lick the medication to prevent poisoning.
Secondly, choose a fine-toothed comb and brush your cat's fur daily, especially in areas where dirt and grime can easily accumulate, such as the abdomen, armpits, and tail, to remove fleas and flea eggs.

In addition, it is very important to keep the cat's living environment clean, such as regularly cleaning the litter box and cat bed, to reduce the hiding places of fleas.
Finally, take precautions: take your cat out less often and avoid letting it come into contact with other animals of unknown origin to prevent the spread of fleas.
In conclusion, removing fleas from cats requires a combination of methods, along with a focus on daily prevention and hygiene management.
