How to Make Your Cat Feel Better After Vaccinations?

After receiving their vaccinations, the majority of cats feel and act entirely normal. This is because vaccines are designed to stimulate the cat’s immune system, which helps the cat fight off diseases. However, some cats may experience mild side effects, such as a loss of appetite, lethargy, or a low-grade fever. These side effects are usually short-lived and go away on their own within a few days.

If your cat is feeling unwell or not quite themselves after their vaccination, here are some suggestions to assist them in feeling more comfortable.

  • Furnish a cozy and comfortable sleeping arrangement in a secluded and peaceful location. This will help your cat to feel comfortable and relaxed.
  • Keep in mind that they might experience increased drowsiness or have a desire for solitude. Don’t force your cat to interact with you if they don’t want to.
  • Do not touch or rub them close to the area where they were given the injection as it may be sore. This could make them feel more uncomfortable.
  • Provide them with all the necessary items within proximity, such as their food and water dishes, as well as their litter box. This will make it easier for them to get what they need without having to move around too much.
  • If they are not eating well, you might have to entice them with a delicious treat such as cooked chicken or tuna. Sometimes a change in diet can help to stimulate their appetite.

Although we may desire to offer our cats comfort and assurance, they typically favor being alone for a while following a trip to the veterinarian due to the stress it causes. Don’t worry; let your cat rest and they will come to you when they are ready. Just keep a close eye on them and check on them regularly.

When Should Be Worried?

Mild side effects of cat vaccines

It is normal for cats to experience mild side effects after receiving a vaccine. These side effects can include lethargy, mild discomfort, and disorientation. These side effects are usually caused by the vaccine stimulating the cat’s immune system. They are usually mild and go away on their own within a few days.

Lump at the injection site

A small lump or inflammation at the injection site is also a normal side effect of vaccination. This is caused by a build-up of fluid at the injection site. It should go away on its own within a few weeks. However, if the lump is getting bigger or doesn’t go away after two weeks, you should take your cat to the vet.

Serious side effects of cat vaccines

Serious side effects of cat vaccines are rare, but they can happen. The most serious side effect is anaphylaxis. Anaphylaxis is a sudden and severe allergic reaction that can be life-threatening. Symptoms of anaphylaxis can include difficulty breathing, swelling of the face, tongue, and throat, hives, vomiting and diarrhea, low blood pressure, and shock. If your cat experiences any of these symptoms after being vaccinated, you should take them to the vet immediately.
