Hi everyone, I was wondering if anyone had any experience with something like this. For nearly two weeks my cat has either screamed out loudly when yawning, or tried to restrict a yawn as if it causes her too much pain to do it. She is 18, eating great and without pain, breathing seems normal, no coughing. She has been quite sleepy but it's not very unusal for her to be sleepy for a while then normal again. For the last 2 days she has been more like herself and more awake but still has pain when yawning. She had a dental 8 months ago. I took her to the vet a couple of days ago and he said her mouth and tonsils were fine. She tolerated him opening her mouth up for a good while too. I've googled this but can't seem to find a whole lot.
