Discover essential insights about cat skin tags, moles, and growths. Learn how to identify, when to worry, and tips for keeping your feline's skin healthy!

Noticing a strange growth, skin tag, or mole on your cat can be alarming. As pet parents, we often worry about whether these changes are harmless or signs of something more serious. The good news is that many skin growths in cats are benign, but it’s always wise to stay informed and proactive when it comes to your feline friend’s health. Let’s explore what to look for, potential causes, and when to seek veterinary advice.

⚠️ What to Watch For

Skin tags, moles, and growths on cats can vary widely in appearance. Some may be harmless, while others could indicate underlying health issues. Here are common characteristics to observe:

  • Size: Is the growth small, medium, or large?
  • Shape: Is it round, irregular, or raised?
  • Color: Does it match your cat’s skin tone, or is it darker, lighter, or pigmented?
  • Texture: Is it smooth, rough, or flaky?
  • Changes: Has it grown, changed color, or started bleeding?

It’s also important to monitor your cat’s behavior. Are they scratching, licking, or biting at the area? This could indicate irritation or discomfort and warrants further attention.

🔍 Possible Causes

There are several potential reasons why your cat might develop skin tags, moles, or other growths. While many are harmless, some require medical attention. Here are the most common causes:

  • Skin Tags: These small, benign growths are often caused by skin friction or aging. They are generally harmless but can sometimes become irritated.
  • Moles: Moles are pigmented skin growths that are usually non-cancerous. However, any mole that changes in size, shape, or color should be evaluated by a vet.
  • Cysts: These fluid-filled sacs can appear under the skin and may be caused by blocked hair follicles or oil glands.
  • Warts: Caused by viral infections, warts are uncommon in cats but can appear as small, rough growths.
  • Abscesses: If the growth is red, swollen, and painful, it could be an abscess resulting from an injury or bite wound.
  • Skin Cancer: While rare, malignant tumors such as squamous cell carcinoma or melanoma can occur. Early detection is key to successful treatment.

According to VCA Animal Hospitals, certain breeds, like white or light-colored cats, may be more prone to skin cancers due to sun exposure (source).

✅ What You Can Do at Home

While it’s crucial to consult a vet for any suspicious skin growths, there are steps you can take at home to monitor and care for your cat:

  • Inspect your cat’s skin regularly, especially during grooming sessions.
  • Take photos of the growth to track any changes over time.
  • Keep the area clean and avoid applying any creams or ointments unless directed by a vet.
  • Prevent your cat from scratching or licking the area to reduce irritation or infection risk.

Home monitoring is helpful, but it’s important to avoid making assumptions about a growth’s severity. A professional evaluation is always recommended if you’re unsure.

💡 When to Call a Vet

While some skin tags and moles are harmless, there are certain situations where you should seek veterinary care promptly. Contact your vet if you notice any of the following:

  • The growth is rapidly increasing in size.
  • It has an irregular shape or uneven borders.
  • The area is red, inflamed, or bleeding.
  • Your cat is excessively scratching, licking, or biting at it.
  • There are multiple new growths appearing at once.
  • Your cat seems lethargic, has a reduced appetite, or shows other signs of illness.

A veterinarian can perform a thorough examination, which may include a biopsy, fine needle aspiration, or other diagnostic tests to determine the nature of the growth. Early intervention can make a significant difference, especially if the growth turns out to be malignant.

According to PetMD, regular vet checkups can help catch potential skin issues early, improving outcomes for your cat (source).
