First of all, the breeder needs to ventilate and clean the room to reduce the reinfection of the cat's claws, and then purchase disinfection and anti-inflammatory drugs. First, use a cotton swab to dip the cat's meat pads into the sterilization and disinfectant to clean, and then apply anti-inflammatory drugs. For medicine, it is best to wrap the paws with gauze to prevent the cat from rubbing the medicine off and licking it. During this period, you can also apply erythromycin ointment, change the cat's medicine twice a day, and try to reduce the cat's exercise.
