Cat's Side Effects After Merial's Trifexis Vaccine: Wha

Section 1: Potential Side Effects of Vaccinations in Cats

After receiving a vaccination, cats may experience certain adverse reactions, which can typically manifest as follows:

1. Appetite Loss and Gastrointestinal Discomfort: Cats might show signs of poor appetite, vomiting, or diarrhea within 12 days postvaccination. These symptoms usually resolve as the cat adjusts to the vaccine. However, if the symptoms are severe or persistent, it's advisable to consult a veterinarian to rule out other health issues.

2. Local Injection Site Reactions: The area where the vaccine was administered may become red, swollen, and painful. These symptoms generally last for 1 to 7 days and then diminish. If the symptoms persist beyond a week or worsen, a veterinary checkup is recommended.

3. Rarely, cats may exhibit allergic reactions after vaccination, characterized by paralysis or weakness, rapid development of red, itchy bumps on the belly, red and swollen conjunctivae, and pale, bloodless oral mucosa with abnormal CRT reactions. Immediate medical attention is crucial in such cases, though allergic reactions are quite uncommon.

Section 2: Precautions to Take Before Vaccinating Your Cat

1. Certain cats are not suitable for vaccination, such as pregnant ones, those with illnesses, those not dewormed, or kittens under 8 weeks old. Vaccination can affect the vaccine's effectiveness and, in pregnant cats, may even lead to miscarriage.

2. Cats should not be bathed within one week after vaccination, as the vaccine takes 710 days to become effective. Bathing can weaken the immune system, potentially leading to colds or fevers that could compromise the vaccine's effectiveness.

3. It's recommended to observe your cat for 2030 minutes after vaccination in case of an allergic reaction. This allows for timely treatment if any adverse reactions occur, including the administration of antihistamines if necessary.

4. New kittens should not be vaccinated immediately upon arrival in a new home. It's best to wait at least 15 days to ensure they are healthy and free of diseases before administering the vaccine.

5. Within 13 days after vaccination, your cat's stool may exhibit adverse reactions, which are generally normal. If symptoms persist beyond 3 days, it's important to seek veterinary care.
