Contact dermatitis in cats is a common skin condition characterized by inflammation and irritation from direct contact with an allergen or irritant. Also known as contact allergy or skin allergy, this condition occurs when a substance triggers an immune response, leading to skin damage and discomfort. Contact dermatitis can affect any area of a cat’s body, causing symptoms such as redness, itching, hair loss, and skin lesions. Various factors, including exposure to chemicals, plants, insecticides, or substances in food and water bowls, flea collars, or grooming products can cause the condition.
Feline contact dermatitis can be acute or chronic, requiring prompt attention at the veterinary hospital in Woodbridge to identify and remove the offending agent, manage symptoms, and prevent complications.
What is contact dermatitis?
Contact dermatitis is a type of skin inflammation that occurs when the skin comes into direct contact with an allergen, irritant, or sensitizing substance, triggering an immune response and causing damage to the skin. Characterized by redness, itching, swelling, and blistering, contact dermatitis can be acute or chronic, affecting any part of the body, including the face, hands, feet, and genital area.
