Why is my cat rapidly opening/closing mouth like her jaw is stuck?

My cat is doing a weird mouth motion where she opens and closes her mouth rapidly, like she's trying to get her jaw unstuck or something? It's a very odd thing to try to describe, but I worry that something is wrong with her jaw/mouth or teeth.

Yes, there could be an issue with her teeth or jaw. I suggest you get her to your vet for an exam. If you could take a video with your phone of the behavior she is exhibiting that would be good. That way you can show the vet what she is doing since she may not do it during the exam.

Hello Greg, Thank you for using Petco Pet Education Center, formerly Petcoach. Sorry Kittee is having this issue. She really needs to be seen by a vet. I suggest you video her making this noise to show your vet. If it is only happening when she is chewing them I'm assuming there is a dental issue or some other type of problem in the oral cavity. She could even have a dislocated jaw. I really think a veterinary visit is best in this case. Hope this helps. If you have more questions you can always opt for a private consultation where we can chat back and forth. That way you can ask as many questions as you'd like. Best wishes.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is indeed likely due to mouth discomfort. I highly recommend that you have her evaluated when your veterinarian has decided to proceed with further investigation. If mouth pain due to a dental condition is diagnosed, they can then proceed with therapy based on what they find wrong. I hope they can help her. Mouth pain can be quite distressing. I wish her the best!
