What can cause inflamed lymphnodes in a cat?

Inflamed lymph nodes in a cat can be caused by a variety of factors, including infections (such as bacterial, viral, or fungal infections), immune system disorders, or the presence of tumors. Common infections that may lead to lymphadenopathy include feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), and abscesses from bites or scratches. Allergic reactions and inflammatory conditions can also contribute to lymph node enlargement. If a cat exhibits swollen lymph nodes, veterinary evaluation is essential for diagnosis and treatment.
