Septicemia in cats: what is it and how is it treated?

When we buy a cat we have to do everything possible so that it has everything it needs. In addition to water, food, toys and a safe place where he receives affection, it is also very important that we take him to the vet whenever we suspect that his health is weak or that he has suffered an accident.

If we let time pass and do nothing, then his condition could get very bad to the point of suffering from septicemia , which is, in many cases, fatal.

What is septicemia?


Septicemia is a form of blood poisoning , caused by bacteria that cause life-threatening infections. The immune system reacts by releasing antibodies to fight them, but this can lead to organ failure, and if this occurs, blood pressure would drop and the animal’s life would be in serious danger.

What are the causes?

Septicemia is a disease caused by infections throughout the body, whether in the lungs, abdomen, urinary tract, or other tissues. If left untreated, it spreads quickly.

In the case of cats, the most common causes are :

Symptoms of septicemia

We can suspect that our cat (or, indeed, any loved one) has septicemia if we see that it has:

  • Fast breathing
  • Decrease in body temperature (normal temperature for a cat is 38-39ºC)
  • Confusion
  • Pain when evacuating
  • Difficulty breathing normally, may become panting
  • Shaking chills
  • Decreased urine output

Diagnosis and treatment

If our cat is not well, it must be taken to the vet urgently. Once there, you will have a blood test to measure the red and white blood cells, as well as the amount of hemoglobin in the blood. If septicemia is suspected, you will also test your urine for bacteria. With the diagnosis confirmed, you will be admitted to give you intravenous fluids and medications .

It is normal for us to feel bad about leaving our friend at the veterinary clinic or hospital, but it is the best we can do. We must think that you will most likely need oxygen or even receive blood transfusions if yours cannot clot properly.

How to prevent?

Septicemia in cats can be prevented in several ways:

And finally, we will also help a lot to prevent it if we take him to be castrated , especially if we give him permission to go outside. A neutered cat will not need to go looking for a mate, so it will not get into trouble.


Cats are not super-resistant animals. They are flesh and blood, like you and me. They also get sick from time to time. Let’s help them recover before they have septicemia.
