Cats, our beloved feline companions, can sometimes experience swollen bellies, and it's essential to approach this issue with compassion and understanding. There can be several reasons behind a cat or kitten's swollen belly, and it's crucial to explore these possibilities while keeping your furry friend's well-being in mind.
A cat's swollen belly can result from various factors, including organ enlargement, the presence of fluid or a mass in their abdomen, intestinal parasites, or weight gain. Your veterinarian plays a pivotal role in identifying the root cause of your pet's swollen belly, in some cases, a simple physical examination might reveal the answer. However, more often than not, additional testing becomes necessary to provide a comprehensive diagnosis.
Let's delve into some common causes of a cat's swollen belly.
Organ Enlargement
The abdomen contains numerous organs that can become enlarged, leading to a swollen belly.
1. Liver, Spleen or Kidneys
Enlargement can result from various causes, including types of cancer, infections (especially fungal diseases), inflammatory responses, or reactions to diseases affecting other parts of the body.
2. Bladder
An enlarged bladder and the inability to urinate can be signs of a urinary blockage, a potentially life-threatening condition. This condition is more common in male cats, but can also occur in females.
3. Gastrointestinal Tract
The gastrointestinal tract can accumulate gas, fluid, foreign material, or food, leading to the appearance of a swollen belly. The most concerning of these is if there's something in the gastrointestinal tract resulting in a blockage.
4. Uterus
In unspayed female cats, the uterus can enlarge during pregnancy or become swollen due to the presence of fluid or pus if an infection occurs. The latter condition can be life-threatening, emphasizing the importance of spaying and attentive post-surgical care. Your pet should rest during recovery from surgery and if you notice a swelling is starting to develop, you should contact your veterinarian.
Fluid in the Abdomen
Moderate to large amounts of fluid in the abdomen can result in a cat or kitten swollen belly. Usually, if this is the case, the vet will be able to observe a fluid wave when they touch the area.
Fluid in the abdomen can be a result of numerous diseases:
1. Hemorrhage
Bleeding into the abdomen can be caused by bleeding tumors, trauma to internal organs, decreased platelet numbers or platelet dysfunction and the ingestion of a specific rat poison called an anticoagulant rodenticide.
2. Cancer
Cancer can cause fluid, and potentially blood, to accumulate in the abdomen.
3. Heart failure
Right-sided heart failure can lead to the inability to pump blood out effectively and result in a buildup of fluid in the abdomen. Any concern for heart failure should be considered an emergency and warrants prompt evaluation.
4. Low protein
Decreased production of proteins commonly occurs secondary to liver failure or disease of the kidneys or intestinal tract. When protein levels are too low, blood vessels in the body can become leaky and cause fluid to build up in the abdomen and other parts of the body.
5. Inflammation
Pancreatitis, among other diseases, can cause fluid buildup and inflammation in the abdomen.
6. Viral disease
Feline infectious peritonitis, a viral disease in cats, commonly results in fluid in the abdomen and the appearance of a swollen belly.
7. Rupture of a hollow organ
Considered an emergency, a tear in the urinary bladder, gallbladder or gastrointestinal tract can result in leakage of the respective organ's fluid contents into the abdomen. This can occur secondary to conditions including bladder stones and obstructions of the gallbladder or intestinal tract.
Tasty Tips
Intestinal Parasites
The presence of gastrointestinal parasites can make a cat look potbellied, notes the Cornell Feline Health Center. This is more commonly the cause of a kitten swollen belly as kittens are more likely to have large worm loads. Your vet can determine the presence of intestinal parasites by examining your cat's feces. Treatment normally consists of an oral medicine.
Abdominal Mass/Tumor
A mass or tumor associated with one of the many abdominal organs can result in a cat swollen belly. This is more common in adult cats. An abdominal mass can be benign or cancerous. Testing is necessary to obtain a specific diagnosis.
Based on the location and type of mass, treatment may involve surgery to remove the mass, chemotherapy or monitoring and supportive care with medications.
Diagnosis
If your cat has a swollen belly, it is important to have him or her examined by their veterinarian. A thorough exam and diagnostic testing are essential to pinpoint the underlying cause. Common diagnostic tests include full bloodwork, urinalysis, abdominal ultrasound and/or X-rays, chest X-rays, fluid analysis, and biopsy (if a mass is present). Additional testing for infectious diseases or organ function may be necessary. Your veterinarian will tailor the testing to your individual pet's case.
Treatment
The treatment of a cat or kitten with a swollen belly depends on the underlying cause. It may involve procedures such as removing excess abdominal fluid, medications, or surgery. Throughout the treatment process, it's crucial to closely monitor your pet and follow up with your veterinarian if you notice any changes in their behavior or physical condition. If you ever have concerns about your cat's swollen belly, don't hesitate to reach out to your veterinarian for their expert guidance and support.
Remember that your cat's health and comfort are of the utmost importance. Approaching the situation with empathy and seeking professional veterinary care will ensure the best possible outcome for your cherished feline companion.
