Mastitis in Cats: Causes, Symptoms, and Treatment

Mastitis, the inflammation and swelling of a cat’s mammary gland, is a condition often associated with bacterial infection. While not common, it can occur in female cats, especially those nursing kittens or recently weaned. Prompt treatment with antibiotics is crucial as untreated mastitis can lead to severe illness and even death. In this article, we will explore the causes, symptoms, diagnosis, and treatment of mastitis in cats.

What is Mastitis in Cats?

Mastitis occurs when one or more mammary glands become inflamed and infected. Female cats typically have eight mammary glands, making it possible for multiple glands to be affected. The inflamed glands may feel warm to the touch, appear red, swollen, firmer than normal, and be painful. Additionally, the milk from the affected gland may be thicker and contain visible blood or pus.

Symptoms of Mastitis in Cats

In addition to the physical changes in the mammary glands, cats with mastitis may display systemic signs of infection. These can include fever, lethargy, poor appetite, and vomiting. The pain from mastitis may cause the affected cat to avoid nursing, leading to inadequate weight gain in their kittens.

Causes of Mastitis in Cats

Mastitis in cats is commonly caused by bacteria entering the teat canal and infecting the mammary gland. Several factors can increase the risk of infection, including:

  • Unsanitary conditions: A cat’s environment should be clean and dry to minimize bacterial presence.
  • Trauma: Tissue damage to the teat or mammary gland can create an entry point for bacteria.
  • Milk backup: When kittens abruptly stop nursing or due to anatomical abnormalities, milk can accumulate in the mammary glands, increasing the likelihood of infection.
  • Mammary hyperplasia: After ovulation, mammary glands can become enlarged, potentially leading to infection if the skin over them becomes damaged.
  • Mammary cancer: Infections can develop in and around tumors when a cat has mammary cancer.

Diagnosis of Mastitis in Cats

Veterinarians can usually diagnose mastitis based on physical examination findings, which include signs of infection in one or more mammary glands. To confirm the presence of bacteria, a sample of milk may be analyzed under a microscope. A culture and sensitivity test can provide valuable information about the specific bacteria involved and which antibiotics are most effective. Additional tests, such as bloodwork and tissue biopsies, may be necessary to rule out other conditions.

Treatment for Mastitis in Cats

Treatment for mastitis typically involves a course of antibiotics prescribed by a veterinarian. The choice of antibiotics depends on the individual cat’s case, and adjustments may be made based on culture and sensitivity test results. Commonly prescribed antibiotics include Trimethoprim sulfa, Clindamycin, Amoxicillin, and Cephalexin. Pain relief and supportive care may also be provided, and in severe cases, surgery to remove damaged tissues may be necessary.

Recovery and Management of Mastitis in Cats

Unless surgery or hospitalization is needed, most cats with mastitis can be treated at home. Owners will receive instructions on administering medications and other recommended treatments. Applying warm or cool compresses, or even cabbage leaves, can help alleviate swelling and discomfort. Improvement is typically seen within a few days of treatment initiation, but antibiotics may need to be continued for two to three weeks. If there is no improvement or if the cat’s condition worsens, contacting the veterinarian is recommended.

After recovery, considering spaying the cat is advisable as it is the best prevention method for mastitis since the condition is mostly associated with lactation.
