Mastitis in Cats: Causes, Symptoms, and Treatment Treating and Preventing Mastitis in Cats

Mastitis in Cats: Causes, Symptoms, and Treatment

Mastitis is a disorder that can affect humans as well as animals, including cats. This article will talk about how to treat and prevent feline mastitis.

Mastitis is a condition that affects both humans and animals, including cats. It is a painful and potentially dangerous inflammation of the mammary glands, usually caused by bacterial infections. While it is most common in nursing mothers, it can also occur in non-lactating cats. Mastitis is a dangerous ailment that has to be treated promptly to prevent consequences like abscesses, sepsis, and even death. 

In this article, we'll look at the causes, symptoms, diagnosis, and treatment options for mastitis in cats, as well as how to avoid getting it in the first place.


A mastitis cat can get mastitis from a number of sources, including:

  • Bacterial infections: The most common cause of mastitis in cats is bacterial infections. The bacteria can enter the mammary glands through the nipples, scratches, or wounds, leading to inflammation and infection.

  • Trauma: Trauma to the mammary glands, such as a blow, a bite, or a scratch, can also lead to mastitis. This is because the trauma can cause damage to the mammary tissue and create an environment for bacteria to grow.

  • Retained milk: When a cat's mammary gland becomes engorged with milk, the milk can become trapped, leading to inflammation and infection. This is common in nursing mothers or cats that have recently weaned their kittens.

  • Hormonal imbalances: Mastitis in cats can also be caused by hormonal imbalances. This is because hormones play an important role in controlling the development and function of the mammary gland, and imbalances can disturb this process and raise the risk of infection.

  • Poor cleanliness: Mastitis in cats can also be exacerbated by poor hygiene. This is due to the ease with which bacteria can enter the mammary glands if the area surrounding the nipples is not maintained clean and dry.

  • Immunodeficiency: Cats with compromised immune systems, such as feline leukemia virus (FeLV) or feline immunodeficiency virus (FIV), are more prone to mastitis because their immune systems are unable to combat bacterial infections.

Cat Mastitis Symptoms

A cat nipple infection can result in a variety of symptoms that vary depending on the intensity and origin of the inflammation. Cat mastitis is characterized by the following symptoms:

  • Swelling and redness of the mammary glands: The affected mammary gland(s) may appear swollen, hot, and red. The swelling may be localized to one or more glands.

  • Pain and discomfort: Mastitis can be painful for cats, and affected cats may exhibit signs of discomfort or pain, such as restlessness, vocalization, or reluctance to be touched.

  • Lethargy: Cats with mastitis may become lethargic or lose interest in their normal activities.

  • Loss of appetite: Some cats with mastitis may lose their appetite or refuse to eat.

  • Fever: Mastitis can cause a fever, and affected cats may have an elevated body temperature.

  • Discharge: In some cases, the affected mammary gland(s) may produce a discharge, which may be pus-like or bloody.

  • Lumps or abscesses: Mastitis can cause lumps or abscesses to form in the mammary glands, which may need to be drained.

How to Treat Mastitis in Cats

Feline mastitis is normally treated and managed by addressing the underlying cause of the inflammation and giving supportive care to help the cat recover. The following are some frequent therapy and care strategies for feline mastitis:

  • Antibiotics: To treat bacterial infections that cause mastitis, antibiotics are frequently administered. Antibiotics may be taken for many weeks to ensure that the infection is completely cured.

  • Pain management: Pain relief medication may be prescribed to manage the discomfort and pain associated with mastitis.

  • Warm compresses: Warm compresses applied to the afflicted mammary gland(s) can help relieve pain and inflammation. This can also help to promote milk flow if the cat is nursing.

  • Milk expression: If the cat is nursing, it may be necessary to express milk from the affected gland(s) to prevent milk accumulation, which can exacerbate the infection.

  • Drainage of abscesses: If an abscess has formed, it may need to be drained surgically to prevent further complications.

  • Hormonal therapy: If hormonal imbalances are the underlying cause of mastitis, hormonal therapy may be recommended to help regulate the cat's hormones and prevent future episodes.

  • Supportive care: Providing supportive care, such as a quiet and comfortable environment, plenty of fresh water and nutritious food, and lots of love and attention, can help the cat recover from mastitis.

Prevention Tips

Preventing mastitis in cats is crucial to keeping your feline companion healthy and comfortable. Here are some prevention tips that you can follow:

  • Maintain good hygiene: Keep your cat's living space clean and dry, and regularly clean the litter box. Clean your cat's nipples with a damp cloth to remove any dirt or debris.

  • Monitor your cat's health: Keep an eye on your cat's overall health and well-being, and seek veterinary care if you notice any unusual symptoms or behaviors.

  • Provide a balanced diet: Make sure that your cat is receiving a balanced and nutritious diet, and provide plenty of fresh water to keep your cat hydrated.

  • Encourage a stress-free lifestyle: Make sure your cat has a calm, comfortable home and minimize stress by keeping routine changes and sudden changes to a minimum.

  • Preventing mishaps: Keep your cat indoors or closely supervise outside activities to avoid accidents that could cause harm to your cat's mammary glands.

  • Vaccination for your cat: Vaccinating your cat against infectious diseases like feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) will help boost his immune system and lower his risk of mastitis.

By following these prevention tips, you can help to reduce your cat's risk of developing mastitis and ensure that your feline companion stays healthy and happy.
