A comprehensive guide to common feline skin conditions, from allergies and infections to behavioral issues. Learn to identify symptoms, understand treatments, and keep your cat comfortable.

From minor irritations to chronic conditions, understanding these problems is key to early recognition and effective treatment.
This guide provides a detailed overview of the most common feline skin conditions, their causes, diagnostic methods, and treatment options to help you maintain your cat's skin health and overall well-being.
A healthy cat's skin should exhibit the following characteristics:

Treatment:
Estimated Cost: $100–$300 for initial treatment; $180–$300 annually for prevention.
What it is: An immune system reaction to specific food proteins, commonly beef, dairy, fish, or chicken.
Symptoms:
Diagnosis: Strict 8–12 week elimination diet trial, followed by food challenge testing.
Treatment:
Estimated Cost: $150–$400 for diagnosis; $480–$960 annually for a prescription diet.
What it is: Hypersensitivity to airborne allergens like pollen, dust mites, mold, or grass.
Symptoms:
Diagnosis: Intradermal skin testing, blood allergy testing, and ruling out other causes.
Treatment:
Estimated Cost: $500–$1,500+ annually, depending on the treatment protocol.
What it is: A highly contagious fungal infection of the skin, hair, and nails (not an actual worm).
Symptoms:
Diagnosis: Wood's lamp examination, fungal culture, PCR testing, or skin biopsy.
Treatment:
Estimated Cost: $200–$600 for treatment, plus environmental cleaning.
Types and Symptoms:
Treatment: Prescription topical or oral parasiticides (e.g., Revolution, Bravecto), lime sulfur dips, or ear medications.
Estimated Cost: $100–$300, depending on type and severity.
What it is: A secondary bacterial infection, typically Staphylococcus, following skin damage from scratching or an underlying condition.
Symptoms:
Diagnosis: Skin cytology, bacterial culture and sensitivity testing.
Treatment:
Estimated Cost: $150–$400.
What it is: Overgrowth of Malassezia yeast, often secondary to allergies or hormonal imbalances.
Symptoms:
Diagnosis: Cytology to identify yeast organisms; skin biopsy in chronic cases.
Treatment: Antifungal shampoos, topical treatments, or oral antifungals, plus managing the underlying condition.
Estimated Cost: $100–$300.
What it is: Painful pockets of pus resulting from bite wounds, foreign bodies, or infected injuries. Common in outdoor cats.
Symptoms:
Diagnosis: Physical examination, needle aspiration, and bacterial culture.
Treatment: Surgical drainage and flushing, antibiotics, and pain management.
Estimated Cost: $300–$800.
What it is: A group of inflammatory skin lesions linked to allergic reactions.
Types:
Diagnosis: Clinical appearance, cytology/biopsy showing eosinophils, and an allergy workup.
Treatment: Corticosteroids, cyclosporine, antibiotics for secondary infection, and managing underlying allergies.
Estimated Cost: $200–$600 for diagnosis and initial treatment.
What it is: Inflammation of the hair follicles on the chin and lips.
Symptoms: Blackheads (comedones), red swollen bumps, pustules, and crusting.
Common Causes: Plastic food bowls, poor grooming, stress, bacterial overgrowth, or allergies.
Treatment: Switch to ceramic or stainless steel bowls, topical treatments (benzoyl peroxide), and antibiotics if infected.
Estimated Cost: $50–$150.
What it is: Abnormal skin cell turnover leading to either dry, flaky skin (seborrhea sicca) or greasy, oily skin (seborrhea oleosa).
Symptoms:
Diagnosis: Ruling out underlying hormonal issues, allergies, or parasites.
Treatment: Medicated shampoos, fatty acid supplements, and addressing the root cause.
Estimated Cost: $100–$300.
What it is: Compulsive hair pulling and overgrooming due to stress, anxiety, or boredom.
Symptoms: Symmetrical hair loss on the abdomen, flanks, and legs; skin often appears normal; observable excessive grooming.
Diagnosis: Requires first ruling out all medical causes, followed by a behavioral assessment.
Treatment: Environmental enrichment, pheromone therapy (Feliway), behavior modification, and anti-anxiety medications if necessary.
Estimated Cost: $100–$400.
