Treatment of fungal skin diseases in cats: Pet owners first need to cut off the cat's fur in the severely affected areas, use a syringe needle to break the pustules, squeeze out the pus, and then use hydrogen peroxide or iodophor for disinfection. When the affected area is slightly dry but not very dry, sprinkle ceftriaxone sodium powder for injection. Finally, after the ceftriaxone sodium powder dries, apply Futukang or Da Guoyi cream.
