The skin is the largest organ in the body; it acts like a glove over your cat’s body providing warmth and protection. Secretions from the skin form a barrier to keep germs and water outside the body and bodily fluids inside. Breakdowns in this protective barrier lead to conditions such as: hair loss, infections, and fluid losses. The appearance of your cat’s skin provides insight to the overall health of your pet. Common conditions affecting your cat’s skin include: allergies, bacterial and yeast infections, ringworm, and external parasites, such as fleas and mites.
