Cat had fluid in lungs, stabilized. Why is he still struggling to breathe?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 9 years and 10 months old

My cat had a crisis the other day and was put on oxygen supply and systems because his lungs were filling up with water. He was stabilized, however he still struggles to breathe. Does he just need to rest or do I need to intervene?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Spas! I am so sorry Spas is so sick! Possible causes are congestive heart failure, pleural effusion (from heart failure, infection, cancer, chyle, blood) or cancer. Has your Vet determined the cause. Cats in heart failure can do well once stable but will need to be on life long medications. Only you know what is best for Spas and your family. If he doesn't start improving where he doesn't need oxygen and is breathing normally with in 2-3 days then it is reasonable to think about stopping. If he responds and is back to normal I would treat him until he has another crisis and then consider stopping. I hope this helps and I wish you and Spas the best!
