Bad Breath in Cats
Bad breath, also known as halitosis, can be caused by a
variety of health problems. Don’t worry, your cat’s breath isn’t supposed to
smell minty fresh-but if there’s an extremely strong, fetid odor, there could
be an underlying medical problem.
What Could Be Causing My Cat's Bad Breath?
Most often, bad breath is caused by a build-up of odor-producing bacteria in
your pet’s mouth. This can be a result of dental or gum
disease; certain cats, in fact, may be especially prone to plaque and
tartar. Diet and dermatological issues can also be contributing factors.

Your veterinarian is the best person to pinpoint the cause. A physical

oral hygiene, exercise habits and general attitude and behavior.
When Is It Time to See the Vet?
The following symptoms will require veterinary attention:
- Excessive brownish tartar on your cat’s teeth, especially when accompanied
by drooling, difficulty eating and red, inflamed gums, could indicate serious
dental or gum disease.
- Unusually sweet or fruity breath could indicate diabetes, particularly if your cat has been drinking
and urinating more frequently than usual.
- Breath that smells like urine can be a sign of kidney disease.
- An unusually foul odor accompanied by vomiting, lack of appetite, and yellow-tinged corneas
and/or gums could signal a liver problem.
- Pawing at the mouth
How Is Bad Breath Treated?
Treatment depends on your vet’s diagnosis. If plaque is the culprit, your
cat might require a professional cleaning. If the cause is gastrointestinal or
an abnormality in your pet’s liver, kidneys or lungs, please consult your vet
about steps you should take.

there’s a type he or she recommends.

disease. Some feel that the abrasive action caused by chewing hard kibble can
slow down the formation of plaque.
What Happens If I Ignore My Cat's Bad Breath

of bad breath-can lead to infection and tooth loss.
