Recognizing Symptoms of Feline T-Cell Lymphoma

Feline T-cell lymphoma is characterized by the abnormal growth of T-cells, a type of white blood cells, in various parts of a cat’s body. While the symptoms may vary depending on the affected areas, there are several common signs to look out for. By paying attention to these indicators, you can catch the disease in its early stages and ensure timely intervention.

Physical Signs to Look Out For

Physical manifestations of feline T-cell lymphoma can include:

  1. Enlarged Lymph Nodes: Palpating your cat’s lymph nodes can help you detect any unusual swelling. Lymph nodes are typically found in the neck, under the jaw, in front of the shoulders, and behind the knees. If you notice any enlarged or firm lymph nodes, it may be a cause for concern.

  2. Weight Loss: Unexplained weight loss is often a red flag for various health issues, including feline T-cell lymphoma. If your cat is losing weight despite having a regular appetite, it’s essential to consult your veterinarian for further evaluation.

  3. Gastrointestinal Symptoms: Cats with T-cell lymphoma may experience gastrointestinal problems such as vomiting, diarrhea, or constipation. These symptoms can occur due to the presence of tumors or inflammation in the digestive tract.

Behavioral Changes

Apart from physical signs, feline T-cell lymphoma can also manifest through behavioral changes. Cats affected by this condition may exhibit:

  1. Lethargy: A noticeable decrease in energy levels, increased sleepiness, or a lack of interest in activities they once enjoyed can be indicative of feline T-cell lymphoma.

  2. Changes in Appetite: Cats may experience a loss of appetite or a decrease in food consumption when suffering from this disease. Conversely, some cats may exhibit increased hunger due to the metabolic effects of cancer.

  3. Altered Grooming Habits: Cats are known for their meticulous grooming habits. However, if you notice a decline in grooming or an unkempt appearance, it could be a sign that your cat is unwell.
