Reactions of Cats After Vaccination

Generally speaking, cats do not have any significant reactions after receiving the rabies vaccine. Some cats may experience mild fever, lethargy, and decreased appetite, which usually disappear within 1-2 days. If the symptoms do not subside after a long period, it is advised to bring the cat to a pet hospital for treatment. In addition, some cats may have a stronger reaction or be in a sub-healthy state during vaccination, resulting in vomiting and diarrhea, which also require timely treatment.

Why Do Cats Need to Be Vaccinated?

When a kitten is born, it receives maternal antibodies from breast milk to protect itself. These antibodies gradually disappear after the kitten starts weaning. To protect the kitten from viral infections, we should vaccinate them at around 8 weeks old to enhance their resistance. The three most common and highly dangerous diseases in cats are feline distemper, feline herpesvirus, and feline calicivirus. Therefore, the vaccines against these three viruses are also known as core vaccines, which are essential shots that must be administered.

Reactions of Cats After Vaccination

Cats may experience the following reactions after vaccination. First, cats may exhibit decreased mental and appetite stimulation and become lethargic within 1-2 days after vaccination. Second, cats may have allergic reactions after vaccination, characterized by facial and eye swelling. Third, a small number of cats may experience vomiting and diarrhea symptoms after vaccination. It is recommended that owners observe their cats for half an hour after vaccination before bringing them home. If any abnormalities occur, it is necessary to take the cat to a pet hospital for examination.

What to Do If a Cat Has Adverse Reactions After Vaccination

If a cat shows symptoms such as excessive salivation, widespread itching, and redness and swelling around the eyes, these are manifestations of vaccine allergies. If an allergic reaction occurs, it is necessary to take the cat to a pet hospital promptly for injection of anti-allergic drugs.
