My cat is about 7 years old and his gums have been swollen a few weeks but I barely noticed that it was an actual problem (I thought his mouth was just open all the time..) and I looked at his bottom gums and it turns out he has two bubbles on both sides of his bottom front teeth. I don't usually brush his teeth and He's just healing from feline acne. Can this be associated with his gum problem too?
