Understanding Skin Issues in Cats: Causes, Treatments, and What to Expect

At Audubon Family Veterinary Center, we know how distressing it can be to see your beloved cat uncomfortable or over-grooming. Skin problems are a frequent concern that brings cat owners to our doors. Although feline skin conditions can be complex to diagnose and manage, there’s always a reason behind your cat’s itching, hair loss, or irritation. With the right plan, most cats find lasting relief.

Common Causes of Skin Problems in Cats

Feline skin issues generally fall into two main categories: non-allergic and allergic causes. Identifying the exact source of itching or hair loss can take time and patience.

Non-Allergic Causes

Non-allergic causes may include:

• Anxiety or Stress: Excessive grooming or self-trauma can be a sign of stress.

• Infections: Conditions like ringworm or FeLV can affect your cat’s skin.

• Mite Infestations: These skin parasites are usually diagnosed with a skin scrape.

• Rare Cases: Cancer or immune-related skin diseases might also be responsible.

Diagnosing ringworm involves a fungal culture, which typically takes 10–14 days but can extend up to a month for results. In some instances, we might recommend a trial treatment for mites or ringworm while monitoring your cat’s progress.

Allergic Causes

Allergies are among the most common reasons for skin irritation or excessive grooming in cats.

Flea Allergies

Even indoor cats are not exempt from flea allergies. Just a few bites can cause significant itching. To address this, we suggest using a veterinarian-approved flea preventative, such as Bravecto or Revolution, monthly for several months. Although these products aren’t repellents, they effectively kill adult fleas before they can lay eggs. Full relief can take 3-4 months as the flea life cycle clears from your home.

For more information, we recommend the Your Vet Wants You to Know podcast episode on fleas and flea allergies.

Environmental Allergies

Some cats have sensitivities to environmental factors like pollen, dust, or mold. Antihistamines like Zyrtec may provide mild relief, while supplements such as Omega-3 Fatty Acids and Vitamin E can strengthen the skin barrier and promote long-term skin health.

Food Allergies

Although less common, food allergies can lead to chronic itching or over-grooming. Testing for food allergies involves a strict food trial with a prescription diet for 8–12 weeks, with no other treats or foods allowed.

Advanced Testing and Specialist Care

If your cat’s skin condition persists despite initial treatments, we might recommend further tests like a skin biopsy or bacterial/fungal culture for a definitive diagnosis. For complex cases, a referral to a Veterinary Dermatologist can offer advanced testing, such as intradermal skin allergy testing or specialized therapies.

Patience and Partnership

Diagnosing and managing skin issues in cats takes time, but with patience, consistency, and teamwork, most cats find relief. At Audubon Family Veterinary Center, we strive to make the process as stress-free and transparent as possible, helping you understand each step of your cat’s care.
