Hello- I'm new to this site. I'm very concerned about my cat Romeo. He has had this awful breath since he was a kitten. He's almost 3. The vet said it was normal but it stinks up the room- it's that bad! He's due in for his checkup & I've put off bringing him. Well in the last few weeks he's been kind of acting like something is on his teeth. Then he's been sticking his tongue out a lot lately & when he licks or sticks his tongue out, his jaw will vibrate. Tonight I found his tooth on the floor. I plan to bring him to the vet but until I can get him there, can someone tell me if they know what might be causing this?
