Bad Breath in Cats

If a cat has recently eaten fish, it is normal for its breath to smell like fish. If the fishy or urine-like odor persists, it could be the result of a health problem.

What Causes Bad Breath in Cats?

  • Periodontal disease
  • Metabolic disease
  • Diabetes
  • Gingivitis
  • Stomatitis
  • Oral cancer
  • Neurological disease
  • Abscess
  • Ulcers
  • Tumours

By far, the most common problem and reason for bad breath in cats is periodontal disease.

Gingivitis, periodontitis, and tooth resorption are the three most common dental diseases in cats, and the severity of each of these conditions varies greatly. Both of these conditions can result from lack of dental care (brushing) and dental cleanings, which are done professionally by your veterinarian.



Symptoms of Oral Disease

Dental disease in cats can cause significant pain and discomfort, lowering a cat's quality of life. It also frequently causes a cat to stop eating, which can lead to a variety of health issues.

In general, infection or inflammation are followed by the cellular changes that occur as a result of an immune response triggered by the accumulation of plaque and tartar.


Symptoms of these conditions include:

  • Bleeding gums
  • Bad breath
  • Redness of the mouth and gums
  • Behavioral changes
  • Inability to eat or lack of appetite


However, in order to obtain an accurate diagnosis, your veterinarian must perform a dental examination on your cat.

Treatment typically consists of:

  • Dental cleanings
  • Tooth extraction (if necessary)
  • Antibiotics
  • Dietary changes
  • Addition of supplements
