How to tell the difference between ringworm and acne in cats? - briefly

Ringworm in cats often presents as circular bald patches with broken hairs around the edges, while cat acne typically appears as small, red bumps or pimples on the chin and lips.

How to tell the difference between ringworm and acne in cats? - in detail

Ringworm, also known as dermatophytosis, is a common skin infection in cats caused by fungi, while feline acne is a result of inflammation within the hair follicles and sebaceous glands. Differentiating between these two conditions is crucial for proper treatment and prevention of spread. Here are detailed steps to help you identify each:

  1. Appearance:

    • Ringworm: Typically appears as circular patches of hair loss, often with a red or inflamed base. The affected area may look scaly or crusty. In some cases, the hair loss may not be circular and can appear more diffuse.
    • Acne: Manifests as blackheads (comedones) and pimples around the cat's chin and lip area. These lesions are usually small, dark, and sometimes filled with a white or yellowish substance.

  2. Location:

    • Ringworm: Can occur anywhere on the body but is commonly seen on the head, ears, forelimbs, and tail base.
    • Acne: Primarily affects the chin and lip area, which are regions rich in sebaceous glands.

  3. Symptoms:

    • Ringworm: Apart from hair loss and skin lesions, cats may exhibit excessive grooming, leading to further hair loss and potential self-trauma. Some cats may also experience itching or irritation.
    • Acne: Cats with acne usually do not show signs of discomfort, but the affected area can become inflamed and swollen if secondary infections occur.

  4. Transmission:

    • Ringworm: Highly contagious and spreads easily through direct contact with infected cats or contaminated surfaces. Humans and other pets can also contract ringworm from an infected cat.
    • Acne: Not contagious. It is more likely to be a result of hormonal changes, genetics, or poor grooming habits.

  5. Diagnosis:

    • Ringworm: Diagnosed using a Wood's lamp (ultraviolet light) that can make the fungus fluoresce. However, not all types of ringworm will glow under this light, so further tests like fungal culture may be necessary.
    • Acne: Typically diagnosed based on clinical appearance and location. A biopsy may be required in severe or atypical cases to rule out other conditions.

  6. Treatment:

    • Ringworm: Usually involves a combination of topical antifungal creams, shampoos, and oral medications. Environmental decontamination is also crucial to prevent reinfection.
    • Acne: Treated with topical therapies such as benzoyl peroxide gels or washes. In severe cases, antibiotics may be prescribed if secondary bacterial infections are present.

By carefully observing the symptoms, location, and characteristics of the lesions, you can better differentiate between ringworm and acne in cats. If uncertain, it is always best to consult with a veterinarian for an accurate diagnosis and appropriate treatment plan.
