👉 Feline fluid, also known as lymph, is a clear, colorless liquid produced by the body's immune system to combat infections and diseases. It circulates through a vast network of vessels called lymphatic vessels, which are part of the body's circulatory system but function separately from blood vessels. Cats produce approximately 0.9 to 1.2 liters of fluid daily, with a significant portion being lymph. This fluid contains white blood cells, proteins, and other components that help fight off pathogens and maintain overall health. When the lymphatic system is compromised or when there's an infection, fluid can leak into surrounding tissues, leading to swelling, a condition known as lymphedema. Understanding feline fluid dynamics is crucial for diagnosing and treating various health issues in cats, as it plays a vital role in their immune response and overall well-being.
