Common causes of odorous feline breath – halitosis

Causes can range from oral hygiene to diet to medical conditions or other conditions as well. The issue thus, can come and go or can be very extreme. See the common halitosis causes below:

1. Poor oral hygiene

In many cases, the poor oral hygiene is the main cause this problem. The build-up of foods and odor-producing bacteria are often blamed in this case. When foods particles and foreign bodies are trapped in the mouth, they would rot and make the mouth to smell bad.

Poor oral hygiene in cats or plague and tartar would also lead to infections in the mouth. This would eventually result in ulcers or bumps that would contain pus and smell as well. Infections would also affect the gums and teeth aggravating the whole ordeal. An infection of the teeth, a condition called periodontal disease would also result in such a foul odor.

2. Diet and bad odor

Dietary choices can also have a hand in cat or kitten bad breath., confirms that “Dietary issues can contribute to bad smelling breath with foods such as fish or liver based ingredients contributing to the smell.”

This issue can just be more than oral hygiene or cat’s diet. In rare cases, the feline halitosis can be linked to veiled internal conditions. This could include conditions such as kidney disease, accumulation of toxin in the body, diabetes and liver disease.

5. Traumatic injury

Traumatic injuries to mouth would also lead to sores that can be infected and thus leading to bad smell. Such injuries could be due to teething, hitting mouth against hard surface etc.

Other causes would include mouth cancer, mouth ulcer, and intestinal blockage. Respiratory problems such as rhinitis and sinusitis. They can all contribute towards this problem.
