If your cat’s belly is swelling up in a strange way, it could be a sign of ascites, a disease in which fluid builds up in the abdomen. This can be upsetting for both you and your cat because it usually means there is a health problem going on. This blog post will talk about what ascites is, what causes it, what its signs are, and how to take care of a cat that has it.
What Is Ascites in Cats?
Ascites, which is also called abdominal effusion, is when fluid builds up in a cat’s peritoneal cavity (abdominal cavity) without a reason. This buildup of fluid can make the belly look swollen or swollen all over, and if the fluid puts pressure on the ribcage, it can make it hard to breathe.
Ascites is not a sickness in and of itself, but it is a sign of a more serious problem that needs medical help. Figuring out the reason is important for choosing the right treatment and making your cat’s life better.
Common Causes of Ascites in Cats
Several medical conditions can lead to ascites in cats, including:
1. Heart Disease
Because of poor circulation and high blood pressure in the vessels, conditions like congestive heart failure can cause fluid to build up in the belly.
2. Liver Disease
A lot of what the body does with fluids and proteins is controlled by the liver. When you have hepatic lipidosis, cirrhosis, or liver cancer, fluid can leak into your belly.
3. Feline Infectious Peritonitis (FIP)
FIP is a virus that is caused by a change in the feline coronavirus. The “wet form” of FIP causes a lot of fluid to build up in the belly and usually ends in death.
4. Kidney Disease
Ascites can happen when the body can’t balance its fluids properly because of advanced kidney failure.
5. Cancer
Some types of cancer, like lymphoma or stomach tumors, can make the lymph nodes swell or stop them from draining, which leads to fluid buildup.
6. Trauma or Injury
Ascites can happen when there is internal bleeding from an accident or a fall. If blood vessels break or organs get hurt, fluid can leak into the belly.
7. Protein Imbalances
When the liver doesn’t make enough albumin, a protein, fluid can leak into the belly. Because they aren’t getting enough food, they may have liver or kidney problems.
8. Internal Infections or Parasites
When you have a severe bacterial infection or parasites like heartworms, fluid can build up in your abdomen.
Symptoms of Ascites in Cats
The symptoms of ascites depend on what’s causing it, but here are some common ones:
• Swollen or bloated abdomen
• Difficulty breathing (due to fluid pressure on the diaphragm)
• Lethargy and weakness
• Loss of appetite
• Weight loss despite a swollen belly
• Vomiting or diarrhea
• Pale or yellow gums (if liver disease is involved)
• Increased thirst and urination (if related to kidney disease)
As soon as you notice any of these signs, you should take your cat to the vet right away to get checked out and treated.
Diagnosis of Ascites in Cats
A doctor will usually do the following tests to find out what is causing ascites:
• Physical examination – Checking for swelling, heart murmurs, or signs of illness.
• Ultrasound or X-ray – Imaging tests to evaluate fluid buildup and organ health.
• Blood tests – To check liver and kidney function, protein levels, and infections.
• Fluid analysis – A sample of the abdominal fluid may be taken to check for infections, cancer cells, or protein content.
• Heart tests (ECG or echocardiogram) – If heart disease is suspected.
Treatment and Care for a Cat with Ascites
How you treat ascites depends on what caused it in the first place. This is how doctors usually treat the problem:
1. Draining Excess Fluid (Paracentesis)
In severe cases where the buildup of fluid is making the animal uncomfortable or making it hard for them to breathe, a vet may do a paracentesis, which is a process where they use a needle to drain the extra fluid. This generally only helps for a short time, though, and doesn’t get rid of the cause.
2. Medications
Depending on the underlying condition, your vet may prescribe:
• Diuretics to help remove excess fluid
• Antibiotics if an infection is present
• Steroids or antiviral drugs for FIP cases
• Heart medications if heart disease is the cause
3. Diet Management
People who already have heart or liver disease may be told to follow a low-sodium diet to stop retaining more water. Eating a lot of high-quality protein may also help keep albumin levels in check.
4. Treating the Underlying Disease
• Heart disease may require long-term medication.
• Liver disease treatment depends on the specific condition, but supplements and medications can help.
• Cancer treatments such as surgery, chemotherapy, or palliative care may be options.
• FIP currently has no widely accepted cure, though some experimental treatments have shown promise.
5. Supportive Care at Home
• Keep your cat comfortable with a quiet, warm place to rest.
• Monitor breathing and look for signs of distress.
• Ensure hydration by providing fresh water.
• Follow the vet’s treatment plan carefully.
Prognosis: Can Cats Recover from Ascites?
What will happen to a cat with ascites varies on what caused it. Heart disease, illnesses, and some other conditions can be controlled with medicine and changes to how you live your life. But the future is worse for people with FIP or advanced cancer.
Quick veterinary care is very important because early diagnosis and treatment increase the chances of a better result.
Final Thoughts
Ascites in cats is a serious disease that means there is a bigger health problem going on. If you see your cat’s belly getting bigger or any other signs of pain, you should take them to the vet right away. Some reasons can be fixed, but others might need long-term care or palliative care.
Your cat’s happiness and health are the most important things at the end of the day. You can help your cat have the best quality of life possible by giving it the right care and getting help from a vet.
