In this article, we will talk all about vaccination allergies in cats, along with their symptoms, ways of recovery, and common vaccines which are most likely to cause allergies to your kitty!

So, without further ado, let’s dive right in!

Why Is My Cat Acting Strange After Vaccination?

Well, as stated before, the main reason behind your Cat Acting Strange After Vaccination is the rare feline medical condition called Vaccination Allergy. Much like the side effects of vaccination, these allergic reactions make your cat sick and stressed, along with showing many other worrisome symptoms.

These Vaccination Allergies are caused due to the overreaction of the cat’s immune system to the antigens introduced in their bodies by the vaccine. This results in the kitty becoming hypersensitive to the medicine, which directly leads to allergic reactions in their bodies.

In such cases, these reactions can be both mild and moderate, with a chance of becoming severe if ignored and mistreated. So it’s advised that you rush directly to the vet for a proper checkup as soon as you find your Cat Acting Strange After Vaccination.

Now, let me tell you that you don’t have to panic since these allergic reactions last for a very short period of time and are typically non-threatening in the majority of cases. However, it’s essential to be proactive and consult the vet as soon as the symptoms start to show up.

Also, rest assured since less than 10 cats in every 10,000 vaccinated show any signs of vaccination allergies, which means that the chances of your cat suffering from it after vaccination are very low.

In any case, it is advised that you don’t take any chances and always give a call to the vets since their advice is invaluable and ensures the overall well-being of your kitty!

Cat Acting Strange After Vaccination: Allergic Symptoms

You see, the symptoms of Vaccination Allergy can either be mild or moderate, with a chance of becoming severe if not treated with care. It all boils down to the way your cat’s immune system behaves and how hypersensitive your cat’s body actually is.

Usually, the symptoms are mild and are easily dealt with by the help of normal medicines, but in very rare cases, the symptoms can get severe, which can cause a lot of damage to your cat’s well-being. So we strictly recommend you visit your vet or at least inform them of your Cat Acting Strange After Vaccination.

Now, keep in mind that the chances of your cat suffering from the Severe Symptoms are very low, but you still don’t want to ignore any of these symptoms as they can go from mild to severe at any moment!

So we strictly recommend you consult your vet immediately after your cat starts to show these early signs. Early detection of any medical issue is crucial since it leads to quick recovery from that problem!

Common Allergy-Causing Vaccines

Remember, there is no guarantee that your cat will be allergic to any of these vaccines. However, in all the cases of feline vaccine allergies, these particular medications have been found to be the reason behind most of them.

It all trickles down to how hypersensitive your cat is and how her immune system works. If she has a strong immune system, then she will likely have no problem getting all these vaccines. However, if she has a weaker immune system, then there is a chance she might get an allergic reaction from these vaccines.

Common Allergy-Causing Vaccines:

Feline Panleukopenia
Rabies
Giardiasis
Feline Leukemia Virus
Bordetellosis
Feline Herpes Virus

Symptoms of Feline Vaccination Allergy typically appear within the first 24-48 hours of being vaccinated. If your cat is fine within that timeframe, you can relax since she isn’t likely to get sick or start acting weird after vaccination at all!

But if, in those initial hours, you notice your Cat Acting Strange After Vaccination, then it’s likely an issue, and you must visit your vet or at least inform them of the symptoms.

Cat Acting Strange After Vaccination: Recovery & Treatment

Mild to Moderate Symptoms of Vaccination Allergy can be treated with anti-inflammatory drugs such as Corticosteroids and Antihistamines. However, don’t attempt to treat your cat with such medicines on your own since it can be dangerous for her health if you administer the wrong dosage.

Veterinarians consider many intricate factors, such as the cat’s body weight, blood pressure, medical history, and current condition, to determine the proper dosage and medication. Veterinarians are highly qualified to take care of your pet in all situations.

In cases of Severe Symptoms, rush to the vet emergency center since it can escalate into a serious issue if not treated immediately. Never forget to disclose your cat’s past medical history before getting her vaccinated.

If your cat has had a past case of medicinal hypersensitivity, then the doctors simply won’t give your cat the vaccine she was previously allergic to and will administer another safer alternative. This helps prevent allergic reactions altogether!

As the old saying goes: “Prevention is better than cure!”
