Understanding Anemia in Cats
Anemia, a condition characterized by a decrease in the number of red blood cells or the amount of hemoglobin in the blood, can affect cats too. It is important to understand the causes and types of anemia in cats to better comprehend conditions such as feline autoimmune hemolytic anemia (AIHA).
Causes of Anemia
Anemia in cats can have various underlying causes. Some common causes include:
- Infectious blood parasites such as Mycoplasma haemofelis or the feline leukemia virus (FeLV) can lead to anemia.
- Cancers, bacterial infections, hereditary abnormalities, toxin exposure, and reactions to drugs or vaccines can also result in anemia in cats (Small Door Vet).
Types of Anemia in Cats
One type of anemia that affects cats is feline autoimmune hemolytic anemia (AIHA). AIHA occurs when the body’s immune system attacks and destroys its own red blood cells. In cats, the secondary type of AIHA is more common. It is triggered by diseases such as feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), cancer, or toxins that alter red blood cells, causing the body to produce antibodies to destroy them (WagWalking).
Another form of anemia observed in cats is immune-mediated hemolytic anemia (IMHA), which occurs less commonly in cats compared to dogs. IMHA can be secondary when attributed to an underlying disease or primary (idiopathic) when no cause is found. Underlying causes of IMHA in cats can include infections, cancer, drugs, vaccines, and inflammatory processes (NCBI).
Recognizing the signs of anemia in cats is essential for early detection and prompt treatment.

Understanding the causes and types of anemia helps veterinarians diagnose and develop appropriate treatment plans to address this condition in cats.
Feline Autoimmune Hemolytic Anemia (AIHA)
Feline Autoimmune Hemolytic Anemia (AIHA) is a condition in which the immune system of a cat mistakenly attacks and destroys its own red blood cells. This leads to a shorter-than-normal lifespan for the red blood cells and can result in severe anemia. AIHA can be categorized into two types: primary and secondary.
Primary vs. Secondary AIHA
Primary AIHA, also known as idiopathic AIHA, occurs when the underlying cause of the immune system attacking red blood cells is unknown. It is thought to be a result of the immune system malfunctioning and mistakenly identifying the cat’s own red blood cells as foreign invaders. Primary AIHA is less common compared to secondary AIHA.
Secondary AIHA, on the other hand, is more prevalent in cats. It is triggered by an underlying disease or condition that alters the red blood cells, causing the immune system to produce antibodies that target and destroy them. Some of the common triggers for secondary AIHA in cats include diseases like feline leukemia virus (FLV), feline immunodeficiency virus (FIV), cancer, and exposure to toxins that affect the red blood cells (WagWalking).
Triggers and Underlying Causes
In secondary AIHA, the immune system response is often a result of an underlying condition or disease. These triggers can lead to the production of antibodies that attack the cat’s own red blood cells. For example, feline leukemia virus (FLV) and feline immunodeficiency virus (FIV) can both contribute to the development of secondary AIHA.
Other underlying causes that can trigger secondary AIHA include certain types of cancer, exposure to toxins, and specific medications. These factors can alter the red blood cells in a way that triggers an immune response, leading to the destruction of the affected cells.
The exact cause of primary AIHA is still unknown. It is believed to be related to a malfunction in the immune system, causing it to mistakenly target the cat’s own red blood cells. Further research is needed to fully understand the underlying mechanisms behind primary AIHA.
If you notice any signs of anemia in cats, such as pale gums, listlessness, fatigue, increased heart and breathing rates, poor appetite, anorexia, or vomiting, it is important to seek veterinary care promptly. A thorough diagnosis is essential for determining the type and underlying cause of AIHA in order to provide appropriate treatment and management strategies.
Diagnostic procedures, such as a complete blood count (CBC), can help measure the red blood cell count, packed cell volume, and examine the size and shape of the cells. In cases of AIHA, abnormal clumping of red blood cells, known as autoagglutination, may also be observed.
Understanding the different types and triggers of AIHA in cats is crucial for accurate diagnosis and appropriate treatment. In the following sections, we will explore the symptoms, diagnosis, treatment approaches, prognosis, and preventive measures for managing feline AIHA.
Symptoms and Diagnosis
When it comes to feline autoimmune hemolytic anemia (AIHA), recognizing the symptoms and obtaining a proper diagnosis are crucial for effective management and treatment. Let’s delve into the key aspects of recognizing AIHA symptoms and the diagnostic procedures involved.
Recognizing AIHA Symptoms
Cats with AIHA often present with severe anemia, which can lead to a range of noticeable symptoms. These may include:
- Pale gums
- Listlessness and fatigue
- Increased heart and breathing rates
- Poor appetite
- Anorexia
- Vomiting
These symptoms are a result of the lack of oxygen delivery to the body’s tissues due to the destruction of red blood cells (VCA Hospitals). It’s important to note that symptoms may vary in severity depending on the individual cat and the underlying causes of AIHA.

Diagnostic Procedures
Diagnosing AIHA in cats involves a series of diagnostic procedures to confirm the presence of the condition and determine its underlying causes. These procedures may include:
-
Complete Blood Count (CBC): A CBC is conducted to measure the red blood cell count, packed cell volume, and examine the size and shape of the cells. Abnormalities in these parameters can indicate the presence of AIHA. A blood smear may also be examined under a microscope to observe any abnormalities, such as the presence of autoagglutination (abnormal clumping of red blood cells).
-
Tests for Underlying Causes: AIHA can be either primary or secondary, meaning it can occur as a standalone condition or as a result of an underlying cause such as infections or cancers. To determine the underlying cause, additional tests may be performed. These tests may include assessing for feline leukemia virus, feline immunodeficiency virus, and parasites, which are known causes of hemolytic anemia in cats (WagWalking).

By being aware of the symptoms associated with AIHA and undergoing the necessary diagnostic procedures, veterinarians can accurately diagnose the condition and develop an appropriate treatment plan. If you suspect your cat may be experiencing symptoms of AIHA, it’s important to consult with a veterinarian promptly for a thorough evaluation and diagnosis.
Treatment Approaches
When it comes to treating feline autoimmune hemolytic anemia (AIHA), a comprehensive approach is necessary to address the underlying immune dysfunction and manage the symptoms effectively. The treatment options for AIHA in cats may include blood transfusions and supportive care, as well as immunosuppressive therapy.
Blood Transfusions and Supportive Care
In severe cases of AIHA, where the cat’s red blood cell count is critically low, blood transfusions may be necessary. Transfusions provide a temporary solution by replenishing the red blood cell supply and improving oxygen delivery throughout the body. These transfusions can help stabilize the cat and alleviate symptoms associated with anemia.
Alongside blood transfusions, supportive care is crucial for cats with AIHA. This includes providing a stress-free environment, ensuring proper hydration, and a well-balanced diet. Additionally, your veterinarian may prescribe medications to manage pain, reduce inflammation, and support overall immune system function.
Immunosuppressive Therapy
Immunosuppressive therapy is a key component of treating AIHA in cats. The goal is to suppress the abnormal immune response that is attacking the red blood cells. The primary immunosuppressive medication used is glucocorticoids, such as prednisolone. These medications help reduce the immune system’s activity and decrease the destruction of red blood cells.
In some cases, a combination of medications may be necessary. Azathioprine and cyclosporine are commonly used as secondary immunosuppressive agents. It’s important to note that azathioprine is not recommended for use in cats due to their susceptibility to its myelosuppressive effects (Today’s Veterinary Practice).
The specific immunosuppressive therapy regimen will depend on the severity of the condition and the cat’s individual response to treatment. Close monitoring and regular follow-up appointments with your veterinarian are essential to evaluate the cat’s response to therapy and make any necessary adjustments.
It’s important to understand that the prognosis for cats with AIHA can vary based on the specific diagnosis and the cat’s overall condition at the time of diagnosis. Cats with secondary AIHA caused by infections may respond well to treatment, while those with underlying cancer or viral diseases may be less responsive (VCA Hospitals). Relapses are also common in AIHA cases, highlighting the need for ongoing monitoring and long-term management.
In our next section, we will delve deeper into the factors that can affect the prognosis of cats with AIHA and explore the crucial aspects of monitoring and long-term management.
Prognosis and Recovery
When it comes to feline autoimmune hemolytic anemia (AIHA), the prognosis and recovery for affected cats can vary based on several factors. It’s important to understand these factors and be aware of the long-term management required for cats with AIHA.
