Vaccination refers to injection, and fever refers to fever clinically. The fever of cats after vaccination can be improved through general treatment, oral drugs, injection drugs, etc. Through active and effective treatment, the body temperature can be restored to the normal range. It reduces the damage to the body after vaccination, and also facilitates vaccine absorption, which can effectively prevent diseases. Fever after vaccination is mainly a side effect of the vaccine. It is an adverse reaction after the drug, but it is not particularly serious. If the body temperature is not controlled for a long time, it needs to be treated by injecting drugs, and medical treatment is required if necessary.

1. General treatment

Cats can generally be injected with feline triple vaccine and rabies vaccine. Cat triple vaccine mainly prevents feline distemper virus, feline herpes virus and feline calicivirus, while rabies vaccine mainly prevents feline distemper virus, feline herpes virus and feline calicivirus. For rabies virus infection, the injection of the vaccine will produce antibodies in the body, which can prevent the disease. However, the injection of the vaccine may cause damage to the central body temperature regulation, causing the body temperature to rise, thus causing fever. You need to use a warm towel to wipe the body, which can take away the body temperature. Excess heat achieves cooling effect.

2. Oral drugs

If the body temperature is above 38.5℃ and general treatment has no effect, you can take antipyretic drugs under the guidance of a doctor, which will help the cat’s body temperature. Back to normal.

3. Injection drugs

If the fever is severe and the body temperature is above 39.5°C, general treatment and oral drugs have no obvious therapeutic effect, and the body temperature does not drop, and the fever remains. If it continues to rise, you need to follow the doctor's advice and treat it with antipyretic injections to cool down and control the rise in body temperature.

Cats need to pay attention to their eating habits during fever. You can give the cat more water, which can speed up the body's metabolism and help cool down. If necessary, you need medical treatment, otherwise it will delay the treatment time and affect your health. .
