Wet FIP Fluid Drainage: What Cat Parents Need to Know

At first, it might just look like your cat’s belly is a little rounder than usual. Maybe you think she’s gaining weight, or joke that she might be pregnant. But soon, things change: she’s eating less, sleeping more, and moving slowly, like it’s hard to even walk.

Then her breathing becomes labored. Her once-bright eyes look tired. A vet visit confirms what you never imagined: Wet FIP.

If you’re reading this, you’re probably navigating this tough diagnosis. You may have heard terms like “fluid buildup” or “abdominal drainage” and are wondering what they mean. Should you consider drainage? Is it safe? Will it help?

This guide breaks it all down clearly and compassionately. You’ll learn what fluid drainage is, when it’s recommended, what risks to watch for, and how it fits into your cat’s treatment plan.

What Is Wet FIP?

Feline Infectious Peritonitis (FIP) is a serious condition caused by a mutated form of feline coronavirus. Wet FIP, also known as effusive FIP, leads to fluid accumulation in the abdomen, chest, or both, causing visible bloating, breathing difficulties, and general discomfort.

While FIP was once considered fatal, antiviral therapies like GS-441524 have significantly improved the chances of recovery.

Even so, managing fluid buildup is key, especially early in the healing journey.

Why Does Fluid Build Up?

With Wet FIP, inflammation develops in the lining of the chest and/or abdominal cavity. This causes small blood vessels to leak protein-rich fluid into those spaces.

The result? Pressure on internal organs, reduced appetite, and difficulty breathing. That’s why your vet might recommend draining some of the fluid.

What Is Fluid Drainage (Paracentesis)?

Fluid drainage—medically called paracentesis (abdomen) or thoracentesis (chest)—is a procedure where a veterinarian uses a needle or catheter to remove fluid buildup.

It’s not a cure, but it can offer immediate relief—especially if your cat is having trouble breathing or is visibly uncomfortable.

The goal is to reduce stress on the body while antiviral treatment (like GS-441524) begins working on the root cause.

When Is Fluid Drainage Needed?

Your vet may recommend drainage if:

• Your cat’s abdomen is so swollen that it’s affecting movement or appetite.

• Fluid in the chest is making it hard for your cat to breathe.

• A fluid sample is needed to confirm a FIP diagnosis.

In most cases, drainage is done before or during the early phase of treatment to help stabilize your cat. But it’s not something you want to do repeatedly. Overdraining can cause protein loss, increased stress, and electrolyte imbalances.

While fluid drainage can provide immediate comfort, true recovery starts with antiviral treatment. If you haven’t begun GS-441524 yet, speak with a trusted treatment advisor from CureFIP USA to get started.

Pros and Cons of Fluid Drainage

Benefits:

• Eases breathing and relieves pressure quickly

• Helps your cat feel more comfortable and active

• Provides useful diagnostic insights

Risks:

• Fluid may return unless antiviral treatment is started

• Potential for infection or added stress

• Loss of important proteins needed for healing

Most FIP-experienced vets agree: Drain only when necessary. The priority should be starting antiviral treatment as soon as possible.

How Is the Procedure Done?

Your vet may lightly sedate your cat or use a calming approach to keep her still. A sterile needle or catheter is inserted into the fluid-filled cavity, and the fluid is slowly drawn out into syringes or a drainage bag. The whole procedure usually takes 10 to 30 minutes.

Most cats feel noticeably better afterward, but they’ll still need to be monitored closely for signs of returning fluid or other side effects.

What to Expect After Fluid Drainage

It’s common for your cat to perk up—she may eat, drink, and move more easily. That’s a good sign.

However, if antiviral medication isn’t started, the fluid will almost always come back.

You might also notice:

• Increased thirst or urination

• Mild fatigue for a few hours

• A short-term decrease in appetite from stress

Keep your vet updated and monitor your cat closely over the next 24–48 hours.

Final Thoughts

If your cat has been diagnosed with Wet FIP, you’re not alone—and you’re not helpless. Fluid buildup can be scary, but fluid drainage, when done appropriately, can give your cat some much-needed relief while you begin the real healing process through antiviral treatment.

Frequently Asked Questions

Is fluid drainage a cure for Wet FIP?

No, fluid drainage is not a cure. It’s a supportive procedure that relieves symptoms like bloating and breathing difficulty. True recovery requires antiviral medication, such as GS-441524.

Will the fluid come back after it’s drained?

Yes—fluid typically returns unless the underlying infection (FIP) is treated with antivirals. That’s why drainage is a temporary measure, not a long-term solution.

Is fluid drainage safe for my cat?

When performed by a skilled veterinarian, fluid drainage is generally safe. Most cats feel better afterward, but the procedure should only be done when truly necessary to avoid protein loss or stress.

How many times can a cat undergo fluid drainage?

Most vets recommend limiting drainage to one or two times. Repeated drainage can cause more harm than good by depleting proteins and increasing the risk of infection or dehydration.

When should I talk to my vet about fluid drainage?

Speak to your vet if your cat has a visibly swollen abdomen, labored breathing, or if they need a fluid sample to confirm a diagnosis. Always weigh the pros and cons with your vet before proceeding.
