Feline Anal Glands: A Comprehensive Guide to Health and Common Issues

Cats are amazing creatures that deserve our love and care. However, they are prone to various ailments, some of which may seem bizarre or embarrassing to talk about.

One such issue is the condition of anal glands. In this article, we will provide a comprehensive overview of the location of cat anal glands, the conditions that affect them, and the symptoms that indicate a problem.

Additionally, we will look at the differences between cat and human hemorrhoids.

Location of Anal Glands in Cats

The anal glands or sacs are situated on either side of the cat’s anus, just inside the rectum. They are sac-like structures that produce a liquid that is released by the cat when it defecates or is stressed.

The liquid has a pungent odor that is unique to each cat and serves as a means of communication. However, if these glands become impacted or infected, they can cause a lot of discomfort for the cat, and the owner may notice some troublesome symptoms.

Conditions that Affect Anal Glands in Cats


Hemorrhoids are a common condition among humans, but they rarely affect cats. This is because the anatomy of the feline rectum is different from that of humans.

The rectal veins of humans are connected to the arteries, which can cause swelling when they become congested. In cats, the rectal veins are not connected to the arteries, which means that they do not get enlarged and painful.

Anal Gland Impaction

When the cat’s anal glands do not empty completely, their contents can become thick and sticky, leading to an impaction. This is a common problem that can cause the cat discomfort and pain.

Symptoms of an anal gland impaction include scooting, licking, and biting the anal area and producing a small amount of thick and smelly fluid upon expression of the affected area.

Anal Gland Infection

An anal gland infection occurs when bacteria enter the gland, usually through the duct. This can cause the gland to swell, become red, and produce a foul-smelling liquid.

Other symptoms of anal gland infection include pain, swelling, and redness around the anus.

Anal Gland Rupture

An anal gland rupture occurs when the gland bursts, leading to the release of fluid into the surrounding tissues. This condition can cause severe pain, swelling, and infection if left untreated.

Symptoms of anal gland rupture include a sudden swelling and reddening of the anus, difficulty sitting or lying down, and fever.


Injuries around the anal area can cause trauma to the anal glands, leading to inflammation and infection. Common injuries include bite wounds, scratches, and burns.

Rectal Prolapse

Rectal prolapse is a condition in which the rectum protrudes through the anus. This condition can cause the anal glands to become blocked, leading to impaction and infection.

Symptoms of rectal prolapse include difficulty defecating, bleeding, and a mass protruding from the anus.

Symptoms of Anal Gland Issues in Cats

The symptoms of anal gland issues in cats can vary depending on the underlying cause of the problem. However, some common signs include:

– Scooting or dragging their rear end on the ground

– Licking or biting the anal area

– Foul-smelling fluid coming out of the anus

– Swelling and redness around the anus

– Pain or discomfort during defecation

– Fever or lethargy


Anal glands are an important part of a cat’s anatomy, and when they are healthy, they serve an essential role in the animal’s communication and bowel movements. However, when they become impacted, infected, or ruptured, they can cause severe pain and discomfort for the cat.

As a pet owner, it’s essential to be aware of the symptoms of anal gland issues in your cat and seek veterinary care if necessary. By doing so, you can help ensure that your feline friend stays happy and healthy for years to come.

3) Bleeding from the Anus

Cats are prone to various diseases and conditions that can lead to bleeding from the anus, which may be a sign of many different underlying issues. In this section, we will discuss some of the most common causes of anal bleeding in cats and the urgent situations where immediate veterinary attention is required.

Causes of Anal Bleeding in Cats

Ruptured Anal Glands

When the cat’s anal glands become infected or impacted, they can rupture, causing bleeding from the anus. This condition can be very uncomfortable and painful for the cat and will require immediate attention from a veterinarian.

Bleeding Disorder

Cats can experience bleeding disorders, which can cause blood to leak from the anus. Hemophilia is one such disorder that affects blood clotting, leading to the cat’s inability to form clots to stop bleeding.

Von Willebrand’s disease is another disorder that affects blood clotting in cats.

Anticoagulant Poisoning

Anticoagulant poisons interfere with the blood’s clotting ability, leading to abnormal bleeding from the anus. Rat poison is one of the most common anticoagulant poisons ingested by cats, which can lead to severe bleeding and death if not treated promptly.


Falls, fights, and accidents can cause injury to a cat’s rectum, leading to bleeding from the anus. Any trauma to the area must be treated promptly to prevent complications.


Constipation can cause straining when defecating, leading to the rupture of blood vessels in the anus, leading to bleeding. In severe cases, the cat may also have a hard time defecating and may show symptoms of pain and discomfort.


Diarrhea can cause a cat to strain when defecating, leading to bleeding from the anus. The excess fluid from the diarrhea may also cause skin irritation around the anus and cause the cat to experience discomfort.

Urgent Situations

If you observe large amounts of blood from the anus, this could be a sign of serious concerns and should be viewed as an emergency. Other signs that warrant emergency veterinary care include:

– Severe vomiting

– Severe diarrhea

– Lethargy

– Weakness

– Pale gums

If you observe any of these symptoms in your cat, immediate veterinary attention is required to prevent the underlying condition from worsening.

Failure to respond urgently during such situations can have severe implications on your cat’s health.

4) Smelly Fluid

Cats have anal glands located and secreting fluid in the rectum. These glands release a unique scent that helps to identify individual cats by smell; thus, they play a vital role in communication and marking their territories.

In some cases, however, these glands may rupture or be infected, leading to leakage of a foul-smelling fluid. In this section, we will discuss the causes of smelly fluid leakage from the anus and the measures to take if you suspect your cat has an issue.

Causes of Smelly Fluid Leakage

Anal Gland Secretions

While secreting fluids is a normal function of the anal glands for cats, excessive secretion of fluid or failure to express the liquid may cause leakage and emit the foul smell. In such cases, a veterinary consultation is necessary to help determine the cause and offer a solution.

Ruptured Anal Glands

Ruptured anal glands can cause leakage of smelly fluid from the anus. Such ruptures can be caused by infections, trauma, or impaction.

Ruptured anal glands should be treated promptly to avoid worsening the condition and other complications.

Diarrhea or Pus

Diarrhea and pus can cause skin irritation around the anus, leading to leakage of smelly fluid from the anus. These conditions can be caused by infections, food intolerance, medications, or other underlying health conditions.


Infections around the anal area can lead to the formation of abscesses, which can burst and cause leakage of smelly fluids.

Recommendations for Evaluation

If you notice smelly fluid coming from your cat’s anus, it is important to consult with a veterinarian. Your vet will perform a physical examination to determine the underlying cause of the leakage, which may include, among other things, expression of the cat’s anal glands, a blood panel, and fecal analysis.

These tests will help to determine the cause of the problem and to offer appropriate treatment solutions.


In conclusion, if you suspect that your cat has any of the symptoms discussed above, it is important to seek veterinary attention promptly. Bleeding from the anus can signal a serious underlying condition that requires immediate emergency attention.

Also, smelly fluid leakage can be caused by varying issues, but prompt attention and interventions can help to avoid further complications for your feline friend. Overall, as a pet owner, you should maintain regular veterinary check-ups to mitigate any potential health issues that may arise as they insure the longevity of your pet.

5) Swollen Anus

A swollen anus is a common issue among cats, and it can be caused by various conditions that may require immediate attention from a veterinarian. In this section, we discuss the conditions that may lead to a swollen anus and what to do if you notice such changes in your cat.

Conditions that Cause Swelling

Impacted Anal Glands

The most common cause of swollen anus in cats is impacted anal glands. When the anal glands are blocked or not expressed properly, they can become inflamed, leading to swelling and pain.

Anal Gland Abscesses

Another condition that can cause a swollen anus is anal gland abscess, which is a bacterial infection that develops inside the anal glands. It can be caused by bacteria that enter the gland, leading to the accumulation of pus and swelling.

Anal Gland


Anal gland adenocarcinomas is a rare form of cancer that can develop in the anal glands. It often presents as a lump beneath the tail or a swollen area around the anus and can be very painful.

Rectal Prolapse

In some cases, rectal prolapse can cause the anus to appear swollen. This condition is characterized by the rectum protruding through the anus, causing discomfort, pain, and irritation.


If you notice that your cat’s anus is swollen or they experience any discomfort around that area, consult with a veterinarian for appropriate advice. In cases where the symptoms worsen or appear in combination with other signs such as lethargy and loss of appetite, it is essential to seek immediate veterinary attention.

6) Common Issues with Cat Anal Glands

Anal glands are essential structures in maintaining regular bowel movements and communication among cats through their unique scent markings. However, these glands can become unwell and cause various health complications.

In this section, we will discuss four common conditions that affect cat anal glands, their symptoms, diagnosis, and treatment options.

Anal Gland Impaction

Anal gland impaction occurs when the anal glands do not empty completely or their contents become too thick. This condition can cause discomfort and pain for the cat.

Symptoms of an anal gland impaction include scooting, licking, and biting the anal area. Veterinary diagnosis for anal gland impaction will often involve palpitation of the anal glands, and may involve expression of any impacted fluids.

Treatment may include antibiotic therapy, high fiber diet, and manual expression.

Anal Gland Infection and Abscess

When bacteria enter the anal glands, they can cause an infection that can lead to the development of an abscess inside the glands. A cat with an anal gland infection may have symptoms such as licking or biting the anal area, painful defecation, and a pus-like discharge.

Diagnosis often involves clinical examination, palpitation of the anal area, and needle aspiration to sample the fluid in the abscess. Treatment may involve cleaning and drainage of the glands, antibiotics or surgical removal of the anal glands.

Anal Gland Rupture

When the anal glands rupture, the liquid within the gland leaks into the surrounding tissues, leading to inflammation and severe discomfort for the cat. Symptoms of anal gland rupture include a sudden swelling and reddening of the anus, difficulty sitting or lying down, and fever.

Veterinary diagnosis includes a thorough physical examination and lancing or draining of the affected glands. Treatment involves antibiotics, anti-inflammatory medications, and pain management during the healing process.


Adenocarcinomas are cancerous tumors that affect the anal glands and are rare in cats. Symptoms of adenocarcinomas include swelling, pain, and discharge around the anus.

Diagnosis may include a biopsy and blood tests. Treatment may involve surgical removal, chemotherapy, and radiation therapy, depending on the size and spread of the tumor.


In conclusion, anal glands play a crucial role in the health and well-being of your cat. As such, it’s essential to be aware of the signs and symptoms of anal gland issues, such as impaction, infection, rupture, and adenocarcinoma.

A veterinarian should make a diagnosis and develop a tailored treatment approach. Overall, prioritizing regular check-ups, observance of behavioral changes in your cat, and prompt veterinary attention when concerned is integral in maintaining an overall healthy cat.

7) Tips for Keeping Cat Anal Glands Healthy

Cat Anal glands are not an organ that most cat owners think about regularly, but you can help to keep your cat healthy by taking care of their anal glands. In this section, we will discuss different tips that you can adopt to ensure that your cat’s anal glands remain in good health.

Monitoring Cat’s Poop

Observe your cat’s poop regularly to ensure that it is well-formed, and of the correct consistency. Well-formed poop enables the anal glands to empty naturally when your cat defecates, thus preventing impaction.

Additionally, proper stool consistency enables your cat to empty their anal glands more frequently. Foods that include probiotics, fiber content, and prebiotics can also improve your cat’s digestion and stool consistency.

Impact of Weight

Obesity in cats is a major factor that can lead to anal gland problems. An overweight cat is more likely to develop impaction of the anal glands as they may have difficulty expelling stool through the rectum, causing anal gland secretions to build up inside the gland.

Controlling your cat’s weight by feeding them a weight control diet and establishing exercise routines is essential in preserving their overall health, including their anal glands. Customized weight loss plans involve evaluating your cat’s day-to-day life, metabolism, and overall health to determine the cause of their weight problem.

A veterinarian weight-loss plan involves gradually introducing a weight-management food, setting healthy meal portions, and proper supplementing.

Chronic Issues

In severe cases where impaction, infection, or inflammation of the anal glands are chronic, a vet may recommend surgical removal or drainage. Surgical removal or lancing the affected gland is a last resort after all other treatment options have failed.

Surgery to remove anal glands in cats is a viable option when other treatment options have failed. This invasive procedure involves the removal of the entire anal sac, and a cat is typically placed under general anesthesia during this procedure.

During this procedure, the surgeon removes both anal glands, leading to permanent removal of the targeted problem, including the risk of an ailment.


When it comes to keeping your cat’s anal glands healthy, it is crucial to maintain regular monitoring of your cat’s poop, invest in weight control meals or adopt proper exercise routines. Additionally, understanding the warning signs and symptoms of anal gland problems, regular vet check-ups, and restraining from administering home remedies are essential in ensuring their overall health.

If you observe any signs of discomfort or pain in your cat’s anal glands, consult a skilled veterinarian for guidance and support on treating conditions early on before they become chronic. In conclusion, taking care of your cat’s anal glands is essential in ensuring their overall health.

Common issues such as impaction, infection, and rupture of anal glands can cause your cat severe discomfort, pain, and sometimes critical complications. Inspecting your cat’s poop regularly, paying attention to their weight, and seeking veterinary attention promptly are crucial in maintaining healthy anal glands
