But if there are notes of acetone or rot in the smell, then this can become one of the symptoms of the disease.

Reasons why a cat has bad breath:

  1. Stomatitis - inflammatory processes are observed in the pet’s mouth.

  • Gum injury, causing inflammation. For this reason, the cat stinks of rotten mouth.

Adult cats:

  • Malignant tumors.
  • Diseases of the internal organs of a kitten.
