My cat is smacking jaws, won't eat, drooling, and has bad breath. Why?
Hello. Roxie probably has some significant dental disease, & this is often accompanied by a condition called stomatitis, which is a chronic irritation of the tissues within the mouth. The exact cause is unknown, but it is often multifactorial involving bacterial infections & an abnormal immune system. Your history definitely points to this, but your veterinarian needs to confirm things. Treatment can be relatively simple with antibiotics & periodic use of steroids. Most important will be an initial examination & cleaning of the teeth under general anesthesia. In the worse case, all the teeth may need to be removed because they present an ever presence of antigens in the mouth that promote the painful lesions. The next step is to make an appointment with your veterinarian as soon as possible to start to address Roxie's problems. Good luck & thanks for using Petco Pet Education Center, formerly Petcoach.
