Lymphadenopathy in Cats: Causes, Symptoms, and Treatment

Feline lymphadenopathy is a condition that is characterized by swollen lymph nodes in cats. We break down this condition more in this article.

Lymphadenopathy, or swollen lymph nodes in cats, is a common condition that affects cats of all ages and breeds. As lymph nodes are a crucial component of the immune system, swelling in them typically indicates an underlying infection or illness. Even though lymphadenopathy isn't usually a problem, cat owners should be aware of the signs and seek veterinary care if required.

In addition to discussing the value of early identification and prevention, this article will look at the causes, signs, diagnosis, and available treatments for lymphadenopathy in cats.


A lump on a cat's neck can be caused as a result of several factors, including:

  • Infection: The most common reason behind lymphadenopathy in cats is infection. Bacterial, viral, fungal, and parasitic infections can all cause the cat's lymph nodes to enlarge or inflame.

  • Cancer: Lymphoma, a lymphatic system malignancy, is a frequent reason for lymphadenopathy in cats. Enlargement of the lymph nodes can also be brought on by other cancers, such as metastatic carcinoma.

  • Chronic inflammation: Chronic inflammation in cats can result from autoimmune conditions, allergic reactions, and inflammatory bowel disease.

  • Immunizations: Some cats may experience lymphadenopathy in response to an immunization.

  • Trauma: Lymphadenopathy in cats is occasionally brought on by trauma to the lymph nodes.

Cat Lymph Node Locations

Lymph nodes are found all over the body of cats. Some of the most often palpable lymph nodes in cats may be found here:

  • Submandibular lymph nodes: They are found on either side of the neck, beneath the jaw.

  • Prescapular lymph nodes: They are found directly behind the shoulders, on either side of the midline.

  • Axillary lymph nodes: They are situated close to the front legs, under the armpits.

  • Popliteal lymph nodes: They are found in the legs of animals, just behind the knees.

  • Inguinal lymph nodes: They are found in the groin region, close to the back legs.

You should note that not all lymph nodes are always palpable, and some may be more difficult to locate. Always get advice from a veterinarian if you have concerns about your cat's health.


Depending on the underlying reason and the location of the swollen lymph nodes, the symptoms of lymphadenopathy in cats might change. Nonetheless, some typical signs of feline lymphadenopathy may include the following:

  • Swollen lymph nodes in cats' neck

  • Hard lump on the cat's lower jaw or lump under the cat's chin

  • Loss of appetite

  • Lethargy

  • Fever

  • Vomiting and diarrhea

  • Respiratory symptoms

Treatment and Management

The treatment and management of lymphadenopathy in cats depend on the root reason. Here are some common treatment options:

  • Antibiotics: If the lymphadenopathy results from a bacterial infection, antibiotics like Clavamox may be prescribed to treat the infection.

  • Antifungal or antiparasitic medication: If a fungal or parasitic infection causes lymphadenopathy, antifungal medication like Ketoconazole or antiparasitic medication like Comfortis Flea Chewable may be recommended.

  • Chemotherapy: If cancer is the source of lymphadenopathy, treatment may be recommended to reduce the tumors.

  • Anti-inflammatory medication: If the lymphadenopathy is caused by an inflammatory disease, such as an autoimmune disease, anti-inflammatory medication may be prescribed to reduce inflammation.

  • Surgery: In some cases, surgery may be necessary to remove the enlarged lymph nodes.

Prevention Strategies

Cat lymphadenopathy can be prevented by lowering the risk factors that might cause the illness. These are a few preventative measures:

  • Vaccination: Immunizations regularly can help avoid illnesses that can result in lymphadenopathy.

  • Regular deworming: Regular deworming can help prevent parasitic infections that can cause lymphadenopathy.

  • Good hygiene: Maintaining good hygiene by keeping your cat clean and grooming them regularly can help avoid infections.

  • Proper nutrition: A well-balanced and nutritious diet can help support your cat's immune system and overall health.

  • Routine veterinary check-ups: Frequent check-ups with your veterinarian can help detect and treat any underlying health issues early.

  • Reduce stress: Providing your cat with a peaceful and stress-free environment might be useful because stress can impair the immune system.

Following the above-mentioned prevention strategies can help reduce the risk of your cat developing lymphadenopathy.
