Cat Fever After Vaccination: Possible Causes & Solution

Why Does My Cat Get a Fever After Vaccination?

It's not uncommon for cats to exhibit some adverse reactions within two to three days after receiving vaccinations. These may include fever, lethargy, a decrease in mental sharpness, and a loss of appetite. This is due to the immune system's response to the vaccine, but most of these side effects will resolve on their own.

While your cat is experiencing these symptoms, you can help by ensuring they drink plenty of water, and feeding them probiotics and specialized stressrelieving canned food. Keep them warm and maintain good hygiene. Generally, they should return to normal within two to three days. However, if these symptoms persist or if their temperature remains elevated, it's important to be cautious. Monitor for other signs and consult a veterinarian to address the fever appropriately.

What to Consider When Vaccinating Your Cat?

1. Avoid Vaccinating Sick Cats: Many people schedule vaccinations for their cats, only to find that they're not feeling well on the day of the appointment. Issues like weakness, drowsiness, or a cold with fever can weaken a cat's immune system, making them susceptible to illness after vaccination.

2. Choose a Reputable Vaccination Location: While pet hospitals may be more expensive, they offer the peace of mind that comes with quality care and immediate treatment in case of an emergency. Vaccinating your cat at an unregulated location may seem cheaper, but the quality of the vaccine is uncertain, and timely treatment is not guaranteed, which can be dangerous.

3. Do Not Leave the Hospital Immediately After Vaccination: Some owners rush to take their vaccinated cats home, but this can be risky. Vaccinations carry their own risks, and an allergic reaction can be lifethreatening. At the hospital, they can receive immediate treatment. It's advisable to stay for at least 30 minutes to an hour postvaccination.
