My wonderful kitty Dave is generally very healthy. He cuddles and plays all the time and is always by my side when I’m home. I’ve noticed this a few times but most recently a few days ago- he’ll be breathing very fast (60bpm) and shivering. He doesn’t try to hide and definitely wants to be held or cuddled but doesn’t want to move around. Last time it happened there was a bad thunderstorm and I wasn’t home for the worst part of it. Could he have just been scared? After a little while as the storm does down, he used his litter box and peed a lot, then pooped - also a lot. Buried it. Drank his water, ate some food and was back to purring and playing. I can’t remember if it had stormed the other times he’s acted like that with the rapid breathing and dilated glassy eyes, but i did notice that he’ll cuddle then use the box and feel better. He’s even cried before in his litter box, like it hurt to go poop. But I figured out that only happened when he ate fishy cat food so now he gets beef, chicken or turkey.
Thank you for your email. I'm glad that you have a scheduled appointment with Paige, as if the medications did not work, it deserves a second look. One thing that your veterinarian can do is to take an x-ray of her lungs and make sure that there is nothing to worry about there. If she isn't on heartworm prevention, a heartworm test might be a good idea as well. Without knowing the details of her situation, or being able to examine her, I can't comment more on what might be happening with her. I hope that she recovers well!

Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
