TL;DR: Skin tags on cats are benign, soft, flesh-coloured growths attached by a thin stalk. They are rare in cats compared to dogs, more common in older or overweight cats, and should always be assessed by a vet to rule out malignant lookalikes. |
You're running your hand along your cat's belly or neck during a grooming session and you feel it — a small, soft lump. Nothing painful. No reaction from your cat. Just a tiny flap of skin that wasn't there before. Before you panic, it could simply be a skin tag. These benign growths can appear anywhere on a cat's body, and while they are far less common in cats than in dogs, they do occur. The key issue is knowing what you're actually looking at, because not every lump that dangles from a stalk is a skin tag. Some are ticks. Some are mast cell tumors. Some are early-stage cancers. This guide walks you through exactly how to identify skin tags on cats, when to worry, how vets treat them, and what you can do to support your cat's skin health.
What Is a Skin Tag on a Cat?
The technical term for a cat skin tag is a fibroepithelial polyp, also called an acrochordon, soft fibroma, or fibrovascular papilloma. They are tiny benign overgrowths of fibrous connective tissue and skin cells. They are not infectious, not communicable, not caused by infection.
What makes a skin tag look the way it does is the narrow stalk (called a peduncle) connecting it to the surrounding skin. This stalk is what distinguishes a skin tag from most other lumps. True skin tags are soft to the touch, movable, and usually match or are slightly darker than your cat's normal skin colour.

Skin tags in the cat may occur singly or in tiny groups. They are more likely to develop in areas where the skin rubs against itself or against external objects — armpits, groin, belly, neck, and around the chest. Skin tags on a cat's nose, face, paws, and ears are less common but do happen.
Kittens rarely develop them. Skin tags are far more likely in cats aged eight years and older, particularly those who are overweight.
What Do Skin Tags on Cats Look Like?
The visual checklist matters here. A true skin tag will typically be:
• Soft and flexible — it moves when you touch it, unlike a hard tumour
• Attached by a thin stalk to the skin surface
• Flesh-coloured or slightly darker than surrounding skin
• Smooth surfaced, occasionally slightly bumpy
• Small, usually pinhead to grain-of-rice sized
If the growth is hard, rapidly growing, discoloured (black, purple, or reddish), ulcerated, or causing your cat to scratch at it — that is not a typical skin tag. That is a reason to get to the vet quickly.
Skin Tag vs Tick on Cat
This is one of the most common points of confusion. A tick attached to your cat's skin can look remarkably like a skin tag. The way to tell them apart: ticks have legs visible upon close inspection, they can move or detach if disturbed, and they tend to feel more round and engorged. A skin tag is smooth, has no legs, and will not move independently. If you are unsure, do not try to remove either of them yourself — seek veterinary help.

What Causes Skin Tags on Cats?
The prevailing explanation is friction – places where skin is continuously rubbed against itself or other surfaces build up additional skin cells over time. That is why skin tags are often seen on a cat’s neck (particularly under collars) and in the armpit, groin and belly areas.
There are several reasons why skin tags are more likely to develop:
• Senior cats, especially those over 8, are the most vulnerable
• Weight: An obese cat will have more skin folds and therefore more areas of friction
• Hormonal changes: Imbalances that influence skin cell regeneration
• Diabetes: Insulin resistance has been linked to increased skin tag formation in some diabetic cats
• Ill-fitting accessories: In the long run, tight collars or harnesses irritate the skin
Skin tags on cats are not related to viral illnesses or communicable diseases and are not transmitted from cat to cat. If you are seeing multiple new growths appear rapidly in a short period, that is unusual for a true skin tag and warrants a vet visit.
Are Skin Tags on Cats Dangerous?
In isolation, no — true skin tags are benign. They do not become cancerous. They do not spread internally. Most cats with skin tags show no distress at all.
The danger lies in misidentification. According to Dr. Jo Myers, a veterinarian at Vetster, there is no reliable way to distinguish a benign lump from a malignant tumour just by looking at it. 'Microscopic examination of the cells is necessary to identify the type of growth and determine if it is benign or malignant.' Mast cell tumours and squamous cell carcinomas are among the most common cancers in cats, and both can mimic the appearance of a benign skin tag.

A skin tag that becomes irritated may bleed, scab, or get infected — particularly if it sits in a friction-heavy area or if your cat grooms it obsessively. Infected skin tags require veterinary treatment. Left alone, an infected growth can worsen significantly.
The short answer: treat every new growth seriously until a vet confirms otherwise. Most will turn out to be nothing. But the ones that aren't need to be caught early.
When to See a Vet: Red Flags to Watch For
Do not wait on these signs. Book a vet appointment if you notice:
• The lump is growing noticeably within days or weeks
• It has changed colour — particularly to red, black, or purple
• It is ulcerated, crusted, or oozing
• Your cat is scratching at it, biting it, or appears in discomfort
• Multiple new growths appeared at the same time
• You are unsure whether it is a tick — have a vet check
For stable, slow-growing, soft growths that have been present for a while and cause no distress — annual monitoring at your cat's routine health exam is usually sufficient. But always get a new growth evaluated first before adopting a wait-and-see approach.
How Vets Treat Skin Tags on Cats
If you and your vet confirm the growth is a skin tag, and it is not causing your cat any discomfort, no treatment is required. The vet will document it and monitor it at future visits.
When removal is recommended, several procedures are available:
Surgical Excision
The whole lump is taken out under local or total anaesthetic. This is also known as an excisional biopsy – the tissue that is removed is sent for histology to confirm the diagnosis. Recovery normally requires stitches to be removed at a follow up visit 10 to 14 days after surgery. This is the cleanest way to do it, to get rid of the growth completely and confirm the diagnosis.
Cauterisation
The tissue is destroyed using heat or electrical current. Effective for small, superficial tags. Less common for cats than surgical excision.
Cryosurgery
Liquid nitrogen is used to freeze the tag, causing the tissue to die and fall off. Used for certain types of small skin growths. Your physician will guide you if this is right for your cat’s specific growth.

Never attempt to remove a skin tag at home. No OTC cream, ligature, or DIY method is safe or appropriate for cats. These can cause serious pain, infection, scarring, and incomplete removal — and they carry the added risk of treating a dangerous growth as though it were harmless.
Supporting Your Cat's Skin Health Year-Round
Skin tags aside, your cat's skin condition is a direct window into their overall health. Coat quality, skin hydration, immune response, and inflammatory markers are all influenced by nutrition. The benefits of omega-3 fatty acids for cats in protecting the skin barrier, chronic inflammation, and coat health are well known.

The Bottom Line
Skin tags on cats are usually benign and harmless — but they are also genuinely easy to confuse with ticks, moles, lipomas, and more dangerous growths like mast cell tumours. The safest approach is always a vet evaluation for any new lump, regardless of how innocent it looks. Most will turn out to be nothing. The ones that aren't are exactly why you shouldn't skip that appointment.
For confirmed, non-bothersome skin tags: monitor, leave alone, and check at annual exams. For anything growing, changing colour, or irritating your cat: get it looked at now.
Keep up with routine grooming sessions — they are your best early-detection tool. The more familiar you are with your cat's normal skin, the faster you'll catch something that's changed.

Frequently Asked Questions
What do skin tags on cats look like?
They are small, soft, flesh-coloured growths attached to the skin by a thin stalk. Most are between 1 and 5 millimetres in size and feel flexible when you touch them, unlike firm tumours.
Are skin tags on cats dangerous?
True skin tags are benign and do not become cancerous. The risk is misidentification — mast cell tumours and other cancers can look similar. Always have a new lump assessed by a vet before assuming it is a harmless tag.
Can I tell if it's a skin tag or a tick?
Ticks have legs visible on close inspection and feel round and engorged. Skin tags are smooth, stalk-like, and do not move independently. If you are unsure, let a vet check — do not attempt to pull it off yourself.
Are skin tags common on cats?
No. Skin tags are much more common in dogs. Cats develop them, but they are relatively rare. When a cat does develop one, it is most likely to be older (8+ years) or overweight.
Can cats get skin tags on their paws, ears, or nose?
Yes, though it is uncommon. Skin tags can appear anywhere on the body. They are most often found on the neck, belly, armpits, and groin — areas subject to friction — but the nose, ears, face, and paws are all possible locations.
What is the treatment for skin tags on cats?
No treatment is required if the tag is not causing irritation or discomfort. If removal is desired, surgical excision (most common), cauterization, or cryosurgery may be performed. All procedures should be performed by a vet under appropriate anaesthesia.
Should I try to remove a cat skin tag at home?
Never. Home removal risks serious infection, pain, scarring, and incomplete removal. There is also the risk that the growth is not a benign tag at all — only a vet can confirm that. Always seek professional diagnosis and treatment.
