Cat Abscesses: Causes, Symptoms, and How to Treat Them

If you’ve noticed a painful bump, swelling, or an open sore on your cat, you may be dealing with an abscess. Abscesses in cats are a common issue, especially in those who spend time outdoors or live in multi-cat households. While they can look alarming, cat abscesses are treatable, and with the right care, your kitty can recover quickly and comfortably.

In this guide, we’ll cover everything you need to know about abscesses in cats, including what causes them, how they’re treated, and how to support your cat through the healing process.

What are Cat Abscesses?

A cat abscess is a localized infection under the skin that occurs when bacteria enter the body, often through a bite, scratch, or wound. The immune system responds by sending white blood cells to the area, creating a pocket of pus. These swollen, painful lumps may eventually rupture and leak fluid.

Abscesses can develop anywhere on a cat’s body, but they’re especially common in areas vulnerable to injury. If left untreated, they can lead to serious complications like systemic infection or tissue damage.

Symptoms of Cat Abscesses

Abscesses often form quickly and may be difficult to detect in their early stages. What may begin as a small bump or mild tenderness can quickly become more serious, especially if hidden under fur or in less visible areas. Cats tend to hide pain well, so you might only notice subtle behavior changes at first.

Keep an eye out for these common signs of an abscess on your cat:

• Swelling or a visible lump under the skin
• Redness or heat at the site
• Pain or sensitivity when touched
• Hair loss around the affected area
• Pus or blood oozing from an open sore
• Fever or lethargy
• Loss of appetite or decreased activity

Some cats may hide or become more irritable due to the pain. If you notice any of these symptoms, it’s best to contact your veterinarian and schedule an appointment as soon as possible.

Causes of Cat Abscesses

The most common cause of abscesses in cats is a bite or scratch wound, often the result of fights with other animals. Bacteria like Pasteurella multocida, commonly found in cat mouths, can easily infect these wounds.

Other potential causes include:

• Infected ingrown hairs or clogged pores: These can create a buildup beneath the skin, becoming a breeding ground for bacteria and leading to painful abscesses.
• Dental infections: An untreated dental problem, like a cracked tooth or gum disease, can allow bacteria to reach the root and form a painful abscess inside the jaw or face.
• Impacted anal glands: If the anal glands become blocked and are not expressed properly, they can fill with bacteria and become infected, resulting in a cat anal abscess.
• Foreign bodies (like thorns or splinters): Small objects can puncture the skin and introduce bacteria, especially if they’re not visible or removed quickly.

Cats that go outdoors, live in groups, or are not spayed or neutered tend to have a higher risk of developing abscesses.

Common Locations of Abscesses on Cats

Abscesses can appear almost anywhere on your cat’s body, but there are some spots where they’re more likely to form:

Tooth and Dental Abscesses

A cat tooth abscess (also called a cat dental abscess) can occur when bacteria infects the root of a tooth. These abscesses may cause facial swelling, drooling, bad breath, and difficulty eating. Dental abscesses are often very painful and require prompt veterinary attention.

Anal Glands

A cat anal abscess develops when the anal glands become impacted or infected. Signs include scooting, swelling near the anus, and pain when sitting or defecating. These abscesses may rupture on their own, but they require medical care to prevent further infection.

Chin and Cheek

Feline acne, scratches, or bite wounds can lead to abscesses around the chin and cheeks. An abscess on cat’s chin or cheeks is often caused by bacteria entering small wounds in high-contact areas.

Cat Paw Abscess

Paws are prone to injuries from sharp objects or rough surfaces, especially in outdoor cats. A cat paw abscess may cause limping, swelling between the toes, or licking at the paw.

Cat Tail Abscess

Bite wounds at the base or along the tail can easily turn into an abscess, especially after fights. Watch for swelling, hair loss, or sensitivity in these areas.

Ears

Ear abscesses may result from scratches, mites, or bites. These can cause head shaking, pawing at the ears, or visible swelling.

How Veterinarians Diagnose Cat Abscesses

Diagnosing an abscess typically begins with a physical examination. Your veterinarian may:

• Inspect the area for swelling, heat, and signs of infection
• Use a needle to draw fluid for testing
• Perform bloodwork to check for systemic infection
• In dental cases, use X-rays to evaluate the roots and jaw

In some situations, your vet may also recommend sedation to properly clean and explore deeper or more painful abscesses.

Treatment of Cat Abscesses

The exact cat abscess treatment depends on the size, location, and severity of the abscess. Most treatments involve draining the abscess and removing infected material. Your vet may recommend:

• Lancing and flushing the abscess
• Antibiotics to fight the infection
• Pain relief medication
• Warm compresses to promote healing
• A cone collar to prevent licking or scratching

In more serious cases, surgical intervention may be necessary to remove damaged tissue or thoroughly clean deep wounds.

Cat Abscess Healing Stages

Understanding the cat abscess healing stages can help you monitor your pet’s recovery. Healing typically occurs in the following phases:

1. Inflammatory Stage – Swelling and redness develop as the body fights the infection.
2. Drainage Stage – The abscess may rupture or be drained by a vet, releasing pus and relieving pressure.
3. Healing Stage – The wound begins to close and scab over; antibiotics and wound care support this phase.
4. Tissue Repair – New tissue forms, and fur starts to regrow over time.

Healing may take a few days to several weeks, depending on the severity and treatment plan.

Recovery and Management of Cat Abscesses

After treatment, your cat may need rest, medication, and close monitoring. Tips for managing recovery include:

• Administer all prescribed medications as directed
• Keep the wound clean and dry
• Apply warm compresses if advised
• Prevent your cat from licking or scratching the area
• Schedule any follow-up visits recommended by your vet

Even if the abscess appears to be improving, it’s important to finish the full course of antibiotics to ensure the infection is fully resolved.

Prevention of Cat Abscesses

While you can’t prevent every injury, there are ways to lower your cat’s risk:

• Keep cats indoors or supervise outdoor time
• Spay or neuter to reduce aggressive behavior
• Keep nails trimmed to avoid self-inflicted wounds
• Regularly check your cat’s skin, especially after outdoor play
• Maintain good dental hygiene
• Seek veterinary care for wounds before they become infected
