2. It may also be caused by gastrointestinal disease or gastrointestinal indigestion that causes cats to drool very smelly while sleeping.

3. Gingivitis and dental calculus cause drooling and bad breath. The main reason is that microorganisms or foreign bodies continue to stimulate the oral mucosa, leading to increased saliva secretion. At the same time, food residues in the mouth decompose and ferment, leading to bad breath.
