Why Does My Cat Breath Stink

Your cat’s breath stink because of the plaque bacteria developed in their teeth. It is usually called as halitosis, a medical term to describe the stinky smell that comes from their mouth.

Some small cat breed like the Himalayans and Persians which has a short-nosed feature are commonly prone to halitosis and other periodontal diseases because the teeth are arranged very close to each other.

Causes of Halitosis in Cats

Dental Problem

The foul smelly bacteria that developed in your cat’s mouth are likely the cause of halitosis or bad breath. The bacteria and saliva create a plaque the can be mineralized and turn into tartar if not treated earlier. Thus, leading to periodontal disease or infection especially in the surrounding areas in the teeth.

There are foods that can contribute to halitosis such as fish or liver type ingredients causing the mouth to have an odor. The cat may also accidental ingested something which is made or rubber bands resulting to a blockage in the mouth due to these particles.

The dietary issue is easily manageable. All you need to do is change the diet.

Stomatitis and Gingivitis

The inflammation of the gums is called the gingivitis while the inflammation of the mucous linings in the mouth is known as the stomatitis. Cats are at risk of developing both conditions usually because of dental problems.

Although there are times that it is due to viruses, bacteria, and allergens. Your vet may suggest some further testing to see for any possible infections like the Calicivirus or the FIV.

Metabolic Diseases

How to Prevent Bad Breath in Cats

The best way to deal with this problem is to treat the condition before it gets worst. Oral hygiene can be treated by keeping your cat’s teeth clean all the time and just like what we do, the best way to prevent halitosis is by brushing their teeth.

It helps to remove the plaque easily before it builds upon the teeth. By brushing their teeth, inflammation of the gum may be prevented.

There are cats that will allow you to brush their teeth especially if they are used to this process. Ask your vet about the right toothbrush and toothpaste to use. It is important not to use any human product for them.

If you do so, they will response badly in the effect of the ingredients and may have digestion problem.

Start training while they are young, let them taste the toothpaste using your finger. Once they are happy with it, start holding their lip as they lick the product. If they seem to be comfortable, begin touching their teeth and brush it. After the process, give them a treat as a reward.

Do this repeatedly for the meantime, it is important that they get used to it until they are completely comfortable with the process.

However, if you can’t brush your feline’s teeth, you can still keep their oral hygiene healthy by using products like oral gels. Dental chews are also good to keeping their teeth clean as it can remove the plaque away during the chewing process while enjoying the treat at the same time. Ask your vet about it.
