If your cat has a stinky breath smell, but it smells fruity rather than foul, she might be having diabetes. Diabetes causes ketones to accumulate in the blood, which gives cat a sweet breath smell.
Stinky breath in cats might be due to a condition known as lymphocytic plasmacytic stomatitis, which may be connected to the feline leukemia virus, feline immunodeficiency virus, calicivirus, or Bartonella.
