Managing Abdominal Fluid in Wet FIP Cases: Examples and Recommendations

Effusive feline infectious peritonitis (FIP) can lead to fluid accumulation in the abdominal and chest areas due to blood vessel inflammation (vasculitis). Given this cause, the decision to remove this fluid depends on specific factors. Here, we present two hypothetical situations and our suggested actions for each: Example 1: Enlargement Causing Breathing, Eating or Movement Difficulties

When enlargement causes breathing or eating issues, it's necessary to remove a portion of the fluid, not all. Breathing difficulties stress the heart, potentially leading to increased heart rate and strain. Fluid removal, while causing dehydration and protein loss, becomes necessary here due to the benefits outweighing the costs.

It's essential to be cautious while removing excess fluid, as removing too much can shock your cat's system, even leading to fatal consequences. We generally recommend removing less than 30% of total abdominal fluid. For kittens and older cats with wet FIP, take a more conservative approach compared to adult cats.

Remember that fluid will reaccumulate unless your cat receives GS-441524 antiviral treatment, often starting at 6mg/kg.

Example 2: Visible Abdominal Enlargement, Normal Eating and Breathing

If your cat's abdomen is visibly enlarged, but it is eating, drinking, and breathing comfortably, we advise against removing the fluid. Instead, initiate GS-441524 treatment at a dosage of 6mg/kg. Within 1.5 - 2 weeks of starting FIP treatment, you'll notice a reduction in abdominal swelling as the body absorbs the fluid and eliminates FIP viruses.

In this situation, removing abdominal fluid is not recommended due to potential harm overtops benefits. The fluid tends to return quickly, often leading to dehydration and protein loss. If your cat's eating and drinking habits are unaffected and breathing is normal, avoid further strain on its delicate condition.

Key Takeaways:

• Breathing and Eating Comfort: Avoid fluid removal unless fluid accumulation directly affects breathing and eating.

• Fluid Removal: Exercise caution, removing less fluid than you might initially think necessary to prevent physiological damage.

• Treatment for Cure: Fluid will return unless treated with GS-441524 from The FurPurr. Anti-inflammatory drugs may offer temporary relief but won't stop FIPV replication. Only GS-441524 treatment can lead to a potential cure.

These insights underscore the importance of evaluating the individual context of a FIP-infected cat and tailoring interventions accordingly.
