Veterinary questions? Ask a Vet for Answers ASAP
Hello, you are through to Dr Linda, a UK based vet.
I'm very sorry to hear Fumi has developed this issue.
Unfortunately, open mouth breathing in cats is a red flag. It tells us they cannot get enough oxygen and is a true emergency. Breathing faster than 30 times a minute is too fast.
As she is also lethargic and off her food, she is likely feeling very unsettled and may be dehydrated.
To stress the seriousness of what is going on, I need to tell you that she is at real risk of passing away if not seen by a vet immediately. She needs oxygen and medicine to help her breathe. This cannot be delayed.
Possible causes for her signs would include heart disease, fluid on the lungs, an infection, asthma etc.
Once stable, the vet will run some tests such as a chest x-ray to determine what specific treatment she would benefit from.
If you need to the details for your nearest open vet, please send me your postcode.
Is there any option to have Fumi seen at another clinic, perhaps a referral centre or university?
This is not something I would advise waiting on as it is important Fumi gets oxygen and that we diagnose what is going on.
Unfortunately we are very limited at home so the best thing is to seek veterinary assistance as soon as you can.
You need to minimise stress by allowing her to rest in a cool, dark room.
Ensure the air is well ventilated and free of any dust, smoke or cooking fumes.
Offer warm and tempting food such as chicken but do not force feed her.
Give her space and try to minimise handling.
I'm so sorry that she is so unwell and you are in this position.
I do hope this helps and please feel free to check back in and to keep me updated,
Sending Fumi all the very best.
As long as it isn't too cold or too hot, it is fine. I would allow her to rest where she chooses and feels comfortable.
I would call as it is a true emergency and, if they can help her, they will.
