Cats, like many other mammals, have anal sacs located on either side of their anus, generally at the 4 and 8 o'clock positions. These sacs contain a strong-smelling fluid that, in most cases, is expelled naturally when defecating or exercising. It is believed that these fluids were used by their ancestors to mark territory or as a defense against enemies. Although they play a much less significant role today than in other species, domestic cats also possess these glands.
How do anal sac problems affect cats?
Although most cats expel fluid from their anal sacs without any major problems, occasionally these fluids can build up, which can result in health problems. When this happens, one of the first signs is that the cat will drag its bottom along the floor repeatedly, as if it has parasites. This behavior, known as "sledding," is one of the first signs that the anal sacs are not working properly.
The accumulation of fluid in the anal sacs can lead to infection . If this occurs, you will see the cat licking the anal area incessantly, accompanied by redness and obvious pain. In severe cases, the infection can cause an abscess which, when it ruptures, will release a bloody or yellowish-brown fluid. This condition can lead to the formation of fistulas, small wounds in the anus that do not heal properly. In addition, the cat may develop significant swelling in the affected area, causing intense pain when defecating.
Anal gland infections
Anal gland infections are a relatively common complication when these glands are not emptied properly. They can occur as a result of other factors affecting the cat's digestive system, such as frequent diarrhea or constipation. In these cases, the glands do not release their contents naturally, causing the fluid to accumulate and thicken, which promotes bacterial growth.
Clinical signs of infection include rubbing the rear end against the ground, compulsive licking of the anal area, straining to defecate, and swelling, pain, or even bleeding in the anal area. If your cat begins to show any of these symptoms, it is important to see a veterinarian immediately to avoid further complications, such as abscesses or fistulas.
More serious complications: abscesses and tumors
One of the most serious problems that can arise in relation to the anal sacs is the formation of abscesses . These abscesses are accumulations of pus that form when the infection is very advanced. In some cases, abscesses can fistulize, that is, open and release the pus to the outside, which can create an open wound in the perianal area.
Abscesses and fistulas require medical treatment and, in some cases, surgical drainage of the affected gland may be necessary. Antibiotics are also frequently used in these cases to combat infection. In addition, in severe or chronic situations, surgical removal of the anal glands may be necessary.
If left untreated, anal gland complications can even lead to the development of tumors , such as adenocarcinomas, an aggressive type of cancer often associated with the anal glands. Although rare in cats, early detection of any changes in the animal's behavior is crucial to preventing complications.
Treatment: emptying the anal sacs
The most common treatment for anal gland complications is manual expression of the anal sacs. This is done by applying direct pressure to the sacs to expel the accumulated fluid. Although it can be done at home, it is recommended that a veterinarian teach you how or perform the procedure at their clinic to avoid harming the animal or worsening the condition.
In cases of severe infections, the veterinarian may recommend antibiotics to combat the bacteria that form within the sacs. In cases of abscesses, surgical drainage may be necessary to remove the accumulated pus and reduce inflammation.
If the problems recur frequently or are severe, the veterinarian may suggest surgical removal of the anal glands. This operation, known as a saculectomy, is a safe procedure for domestic cats, as they do not need their anal sacs for daily survival. However, like any surgery, it carries risks that should be assessed by the veterinarian.
Prevention: diet and care
To prevent anal gland problems , it's important to pay attention to your cat's diet. A high-fiber diet can help the anal sacs empty naturally during defecation, reducing the risk of fluid buildup. Maintaining a healthy weight and providing opportunities for regular exercise can also be beneficial.
A good hygiene routine is also important. In cases of older cats or those with recurring problems, periodic manual emptying may be an option to consider to avoid complications. Similarly, regular visits to the vet will help detect any problems before they become serious.
Ultimately, the key to avoiding anal gland complications in cats is caution, observation, and ongoing care. If any signs of discomfort are detected early, treatment will be much simpler and less invasive.
