Do not shave a cat if it has fleas. After shaving, the cat's barrier disappears, which makes it easier for the cat to contract skin diseases and may also cause the cat to have a stress reaction. Moreover, shaving cannot completely eliminate parasites on cats. If you want to completely eliminate fleas on cats, you can use external anthelmintics. When there are fleas on cats, use them every fifteen days.

Methods for treating fleas on cats:

1. Environmental disinfection. Vacuum all corners, then keep the room closed, spray insecticide, and open windows for ventilation after an hour.

2. Use special flea-killing medicine. If your cat has a lot of fleas, you need to use special flea removal drugs to help completely eliminate the fleas.

3. Use a flea comb. Use a flea comb after your cat takes a bath to remove dead fleas or eggs and help remove fleas from your cat.

4. Avoid going out. Don't let your cat go out and run around in the near future to prevent your cat from getting fleas outdoors.

5. Always bask in the sun. Let your cat bask in the sun as much as possible. Sunlight can not only drive away fleas, but also replenish calcium.
