How can I reduce my cat's fever at home?

Dabbing some isopropyl rubbing alcohol on the pads of a cat’s paws can help reduce a fever quickly. If kitty is willing to sit still for a bit, you can also wrap an ice pack in a towel and rest it against his or her body. A fan can also help reduce a fever but again, only if the cat is fairly sedentary and stays in the stream of the cool air. Fevers that persist for >24 hours should be addressed by a veterinarian. Severe fevers over 105F require urgent or emergency care.

Under no circumstances give human antipyretics to a cat !!! Most of them are fatally toxic to cats, even in small doses.
