A cat needs a total of four vaccinations, including three doses of the feline triple vaccine and one rabies vaccine. Generally, the total cost of these four doses is around 400 yuan. The common feline triple vaccine costs 90-120 yuan per dose, while the price of the rabies vaccine varies from city to city.

After a cat receives its first vaccination when it is in good health, it should receive its second vaccination 21 days later, followed by a third vaccination 21 days later. Finally, it should receive a rabies vaccination one week later. Afterward, a rabies vaccine should be administered. If the antibody levels are within the recommended range, the cat only needs one vaccination and one rabies vaccination annually.
