Understanding Flea Anemia in Cats
Did you know that fleas can cause more than just itching? In severe infestations, especially in kittens, senior cats, or cats with underlying health conditions, fleas can lead to anemia, a potentially life-threatening condition.
What is flea anemia?
Fleas survive by feeding on blood. When large numbers of fleas are present, the blood loss can become significant enough to lower a cat's red blood cell count, resulting in anemia.
Signs of flea anemia may include:
Pale or white gums
Weakness or lethargy
Increased sleeping
Decreased appetite
Rapid breathing or increased heart rate
Weight loss
Visible fleas or flea dirt in the coat
Prevention is key
Year-round flea prevention is the best way to protect your cat. Even indoor cats can be exposed to fleas brought in on clothing, other pets, or wildlife.
When to seek veterinary care
If your cat appears weak, has pale gums, or you notice a significant flea infestation, contact a veterinarian immediately. Severe flea anemia can require hospitalization, blood transfusions, and intensive treatment.
