Being bitten by a cat and the cat dies the next day can be worrying, here are some suggestions:

Wound treatment: Wash the wound immediately with soap and water and squeeze out as much blood as possible. Then disinfect the wound with an antiseptic.

Medical Consultation: Consult a doctor or go to the hospital as soon as possible and inform them of the cat bite. Depending on the severity of the wound, your doctor may decide whether further treatment is needed, such as a tetanus or rabies shot.

Watch symptoms: Pay attention to your physical condition, especially in the next few days. If symptoms such as fever, headache, muscle pain, nausea, etc. occur, you should seek medical treatment in time.

Notify authorities: If the cause of your cat's death is unclear, you may consider notifying your local animal control department or veterinarian so they can understand the situation and provide advice.
