Cat with loud crunching noise when chewing

by Scott

My 21 year old male cat has a renal disorder that has been going on for about 3 years. He does not eat much and has lost lots of weight in the last 6 months so he is now very thin and weak. When he eats(soft can food)he makes a very loud crunching noise that sounds like he is chewing on bone that can be heard all over the house. He does not seem to be in any pain.

This has been going on for about 6 weeks. I know he doesn't have much longer to live but I am continuing to support and care for him as long as he is not in pain or discomfort.

Any ideas what could be causing this?



Hi Scott
Well it could be that as he has lost weight he has also lost muscle tone meaning that the bones in his body have little support and are more likely to start to rub against each other.

My old cat had a illness which meant that she became painfully thin and in the end she broke her leg simply because their was not enough muscle to support the leg.

It could be a similar situation with your cats jaw. However an examination of the jaw area would be need to make sure that there was nothing else wrong. But as you say as long as the cat is able to eat properly and does not appear to be in pain then i don't think there is much you need do. I'm not even sure a vet would be able to do much anyway.

God bless you for taking care of this poorly kitty.

Crunching noise here, too

Yep, my 18 yo cat does this too. She had a stroke a year ago and turns to the left. She's gotten used to this life, but this is new for a week or so now. It's a strange sound. Like spinning one of those vintage metal noise makers. What in the world could this be?

My cat is making same noise since a seizure/stroke

My 19 year old is making the same crunching noise when she eats. It started after a long seizure/stroke. She turns her head to the left, and seems to be making the noise on the right, like TMJ? I will take her to a Vet who is a chiropractor for pets, to see if anything can be done.
