Fluid in abdomen in cats

Also known as abdominal effusion, ascites in cats is not a disease in itself, but rather a clinical sign that alerts of a present pathology. This condition occurs when there is an abnormal accumulation of fluid in the abdomen. Ascites in cats can be caused by an osmosis spill through the blood vessels or the lymphatic system.

Ascites in cats: treatment

Treatment of ascites in cats depends largely on the root of the cause. For example, an infection will be treated with antibiotics, while trauma may require surgery. Tumors may require both surgery and medications. Additionally, a diagnosis should only be done by a professional.

When it comes to ascites cats treatment, ascitic fluid drainage is necessary. In addition, all felines suffering form ascites in cats should be offered a diet low in salt to avoid fluid retention. In some cases, a professional may also prescribe diuretics.

You're welcome. I shared this article on some social media sites to alert other cat owners of this condition.

Thank you for posting this article. I've never heard of this disease before. It sounds really serious. We take our cats (I have three) to the vet for their regular check ups, every year, and so far our vets have not mentioned this disease at all. Hopefully our cats do not have this. My one cat Shadow has a large belly that hangs down, but so far none of our vets has said anything about it. But they check it out when Shadow has an examination. This was a good article. Glad I saw it. :-)
