We just got back from the vet. Sorry for all the typos; I'm a mess.
So for a while now (I don't know, maybe a month or so) I've been hearing her wheeze sometimes when I have her lie on her side during shot time, and I've been hearing a crackling noise sometimes when she purrs. Last time she was at the vet I mentioned it and they listened to her and heard the wheeze but said it went away when she shifted, so it was due to her being overweight. They didn't seem concerned.
This morning I was hearing the crackling again while she was purring and decided to take her back. She's doing good otherwise...eating good, drinking good, usually ok BMs, glucose doing much better (just checked it now and it's 172 and I think that's pretty good for just coming back from the vet).
So I was surprised when they did the xrays and showed me how little breathing room she had. They said normally you see a lot of black space but she had very little black space left and so they needed to treat and gave her a Lasix shot. They gave me Lasix to give her orally .4 ml twice daily, and said they will send out her info to a cardiologist and get back to me Monday. They said she may have heart disease and need to be on Lasix the rest of her life, but they really don't know for sure. They said could be thyroid, a mass, whatever...I asked about FIP and they said they could run a FIP test if I wanted but her bloodwork (which included coronavirus test) looked good so they doubted it. But they really don't know for sure and to wait until we hear from the specialist. Seems like they're leaning more towards heart, though.
I'm so worried if it's anything really bad. I thought it sounded like she had fluid in her lungs because it reminded me of how I sounded and felt when I had fluid due to bad allergies. Today is my birthday too so not the best way to spend the day. If I'd have known she was struggling to breathe, I'd have taken her so much sooner. Goes to show with cats they are so good at hiding things and you really have to overreact to the slightest anything because you don't know what could be a legitimate problem or not.
I asked the vet if I should take her to the teaching hospital, which on weekends is pretty much only emergency now, but they're the only ones I really trust. However, she didn't see the need for it. If you guys think I should, I will though. I asked her results to get sent to them, too, because they have cardiologists.
Any advice or stories or anything would be greatly appreciated.
