This is my first time in the forum, and I hate for it to be under these circumstances. After much thought, consideration, research, and investment, my husband and I adopted a cat from a cat rescue. He had been health checked, neutered, and given his first set of vaccines. He is about 5 months old. Tues night we noticed our new kitty was having trouble breathing -- he was breathing so hard that he was using his whole body to breathe. He wouldn't let me pick him to listen to him. I could tell he must be hurting. I laid down on the floor next to him and let him come to me so I could listen to his breathing. He nuzzled against me, happily purring, then I heard him gasp.... purrrrr... gasp.... There was no coughing or sneezing, though. We took him into the vet first thing Weds morning. The vet took an x-ray and found lots of fluid in and around his lungs. They sent out for testing the fluid and some blood. The vet was worried it's FIP, Feline Infectious Peritonitis. Of course, I'm flipping out! This is my first cat (though my husband was raised with cats). They put our kitty in an oxygen cage, and he was happy to have that! The first night they pulled about 5 tsp. of liquid out of his lungs to help him breathe. The next day, a little over 2 ounces out. Today, he was breathing better and they took him off the oxygen for about 6 hours to see how he'd manage. He did ok; he ate and groomed and went to the bathroom normally. The test results are basically this: 1) the fluid in the lungs looks like either FIP or a cardio-vascular problem, 2) his blood came back positive for corrona virus, though not at extremely high levels, 3) the protiens in his blood are normal. The vet has told me that she is pretty much convinced it's FIP. From everything I've read and everyone I've talked to, FIP is fairly uncommon. We plan on bringing him home tomorrow and keeping up a regimin of anti-biotics and closely moniter his breathing and health. We're so worried though. Has anyone come across anything like this or had a similar problem? I'm just so worried about my kitty!
