Under normal circumstances, it is best to take a newly purchased cat to the pet hospital for a health check before entering the house, and then go home after being vaccinated. Healthy pet cats can be vaccinated about a week after successful weaning. At the same time, vaccinating cats is contraindicated.

Vaccine immunization is something that every cat should do after birth. It can prevent the occurrence of some serious infectious diseases, but vaccine is also a weak virus, which promotes the production of antibodies in cats. When the cat's own immune resistance is abnormal, the injection of the vaccine will have the opposite effect. Therefore, after the cat is born, the state of the cat must be observed first, and the healthy cat can be vaccinated.

The age, health, fitness and nutritional status of the animal should be considered when vaccinating. Do not take a bath for one week before the injection, ask the doctor to take the temperature before the injection, and ensure that the cat can be vaccinated under the premise of being healthy. You can't take a bath after the injection, and you must complete the first-year immunization process. After each injection, the cat's mental and appetite excretion should be closely observed for changes.

In general, before vaccination, the veterinarian should perform a clinical physical examination of the cat, including temperature, respiration, heart rate, physical examination and medical history. The body temperature of normal kittens is 38-38.5 ℃, and that of adult cats is about 38 ℃, but they should not exceed 38.7 ℃, unless individual cats have just come out of the hot car, the body temperature may be slightly higher. Physical examination mainly observes the presence of eye secretions and snot, the color of the oral mucosa, the presence of blood vessels in the conjunctiva, the presence of vomiting, lack of food, diarrhea, etc., whether there is a history of infectious diseases, and whether there is any contact with sick cats. Pass.

Generally speaking, cats should not be vaccinated in the following situations:

1. Generally, cats cannot be vaccinated when they are less than eight weeks old. Small pets should consider the interference of maternal antibodies and should be vaccinated according to the vaccine instructions. Generally, when a cat is twelve weeks old, the maternal antibody in the body has dropped to a non-interfering level. The last vaccination of most infectious diseases should be at the age of twelve weeks or later, so that the pet can be protected. Older cats, although they may have various antibodies in their bodies, may have low titers, which are not enough to protect against disease, and still need to be vaccinated according to the immunization schedule.

Second, cats with poor constitution and malnutrition should not be vaccinated.

3. Cats should not be vaccinated when they are sick. Vaccination at this time, due to vaccine reaction aggravated the disease.

4. Attenuated vaccines are generally not suitable for pregnant female cats due to the strong reaction after injection, especially pregnant female cats cannot be injected with Feline Panleukopenia (feline plague) vaccine, which can pass the placental barrier Infection of the fetus, resulting in stillbirth, miscarriage, premature birth, or birth of a fetus with abnormal cerebellar hypoplasia. If pregnant female cats are vaccinated, inactivated vaccines can be used.

The newly purchased cat should go to the veterinary hospital for examination, or be kept in isolation for seven days before vaccination can be given when it is in a healthy state. Cats need to be vaccinated against rabies when they are three months old. The chances of cats getting rabies are not high, but once they do, the mortality rate is 100%.
