What is Bad Breath?

Bad breath (halitosis) is only a real problem if it becomes chronic or is severe. Of course, your cat’s breath is most likely to smell like the food that it just ate. Some experts suggest that soft or canned foods might lead to worse breath; dry food can cleanse your cat's teeth. The following might signify internal problems - ammonia, citrus or sickeningly sweet feline breath.

Feline halitosis (bad breath in cats) could be caused by food, infections or something more serious, like diabetes or liver cancer. Chronic cat's bad breath could be due to a serious internal disease.

Symptoms of Bad Breath in Cats

Your family pet might like to rub noses with you or the kids, giving you a great chance to get a whiff of its breath. When a foul-smelling odor startles you, then your cat might have a significant problem. Here are the symptoms that may accompany bad breath in cats:

  • Aggressiveness
  • Appetite loss
  • Bleeding gums
  • Depression
  • Diarrhea
  • Drooling
  • Excessive urination
  • Irritability
  • Lethargy
  • Mouth dysfunction
  • Oral cavity lump
  • Pain
  • Pawing mouth
  • Poor coat condition
  • Putrid odor
  • Reclusiveness
  • Swelling
  • Thirst
  • Vomiting
  • Weight Loss
  • Yellow, red or runny eyes

Of course, the difficulty with bad breath is that it also might be a symptom of other maladies. Is your cat more aggressive, irritable or reclusive with its bad breath? Does your cat start to eat, then jump back? This could be due to a painful tooth infection.

Swelling could occur in the gums, mouth or stomach. Does your cat have difficulties opening or closing its mouth? Mouth dysfunction could be a sign of a more serious ailment.

Causes of Bad Breath in Cats

Kitty halitosis can be caused by something as simple as smelly food or something as complicated as liver cancer. It could be a tiny obstruction, like food, a thread or a pebble. Bloody gums could be caused by an electrical cord injury.

Plaque or tartar can lead to viral, bacterial or fungal buildup. Tiny polyps, infections or an abscess might develop. Gastric acid reflux also stinks.

Your baby cat might be teething. Normally, cats have baby teeth fall out between 3 and 6 months.

Somewhat minor ailments causing bad breath could include endocarditis (inner heart tissue layer infection), esophageal tube enlargement, gingivitis, pharyngitis (inflammation of throat), rhinitis, sepsis (bacterial colonization of blood), sinusitis, stomatitis and tonsillitis (inflammation of tonsils). Coprophagia (eating of feces) could also be the cause.

Serious maladies leading to bad breath could include the following: Bartonella henselae, diabetes mellitus (sugar diabetes), gastrointestinal, immunodeficiency virus renal failure, kidney, liver, neurological, periodontal, respiratory or skin diseases.

Diagnosis of Bad Breath in Cats

Veterinarians will conduct blood, biochemical or urinalysis diagnosis tests to determine the cause. These might include more specific FeLV or FIV tests. Ultrasound and X-rays display your cat's internal bone structure.

The veterinarian is likely to complete a physical examination of your cat's tongue, lips, gums, roof and back of the mouth. The vet might need to sedate your pet. The dental vet will also exam tooth mobility and sulfide concentrations, while your cat is under a local anesthetic.

Treatment of Bad Breath in Cats

Vets will search for any obstructions, injuries or infections. While you might want to simply give your cat human toothpaste, this is not advisable, because this is not meant to be swallowed. Also, cats don't like to have their mouths pried open forcibly.

Semi-annual professional cleansing, and polishing of your cat's teeth, gums, and mouth, is advised. Veterinarians might offer same-day blood work and general anesthetic tooth cleaning for removal of tartar, plaque, and abscesses. If severe oral disease is at fault, then tooth extraction may be necessary.

Corticosteroids and other antibiotics are used to treat stomatitis. Cancer treatment would require surgery, chemotherapy or radiation.

Recovery of Bad Breath in Cats

Of course, the recovery time for your cat will vary dramatically depending on the cause. If the feline halitosis is only due to something stuck under the gums, then your cat should enjoy a full and immediate recovery. On the other hand, liver cancer and others serious diseases could be life-threatening.

After a complete professional dental cleaning, your cat may be required to stay in the hospital for recuperation. Multiple tooth extractions could require the addition of fluids, pain medications, and oral antibiotics. The veterinarian will discuss what the owner can do to prevent the cat halitosis from recurring.

Hello If your kitten's breath is bad, I recommend that you take him to a veterinarian. It could be related to his diet or he could have something stuck in his mouth. Good luck.

I have a younger cat who we rescued and after having him for over 3 years his breath has progressively worsened. It has a fishy rancid smell as if there is infection or death. He frequently drools and does not clean himself very well if at all. Our other cat eats the same diet and cleans himself very well and has wonderful breath.

my 9 month old female cat has a couple of knots on her throat and horrible breath. She is aggressive most of the time. She bites a lot. I had her shots and she is fixed. I asked the dr. to look at her then and he said it was her teeth it would go away. When we had her fixed she was 3 months old. Its only gotten worse. She also had a hernia that was fixed at the same time I had her spade. Please help me. I love her so much. I don't have the money to keep taking her back to the dr but I will if I have too. I just don't want it to be cancer.

Without examining Greyson I cannot say what the masses around the throat are or which structures they originate from; lymph nodes, salivary glands and other structures are in the throat which may cause a variety of different issues. If her breath is smelling bad and there are masses around the throat, I would recommend you visit another Veterinarian for a second opinion. Regards Dr Callum Turner DVM

Thank you for your email. Without knowing where the polyp was removed from, or how long ago, i find it difficult to comment on what might be going on with her. Sometimes polyps can recur, but I'm not sure if that is what is causing her bad breath. It would be best to follow up with your veterinarian to see what the source of the problem is, and if further care is needed for her. I hope that everything goes well for her.

There are various causes for the symptoms which you have described which include dental issues, infections, allergies, foreign objects, parasites, tumours among other issues; if Filip is blocked up with his nose it may be worth trying to keep him in the bathroom whilst you shower as the humid warm air may help loosen any discharge in his nose offering temporary relief. It seems that your Veterinarian is treating for everything as there doesn’t seem to be a specific underlying cause, a antihistamine (cetirizine 5mg per day) may help but first wait to finish the current course of treatment with doxycycline.

Stinky Breath, Diarrhea

Adopted a 3 mo. kitten from the Humane Society almost three weeks ago. She was having very liquid diarrhea when I first got her so I tried adding a little Miralax to her food. It improved a little. Then added a feline approved probiotic once a day. I was curled up to her on the couch and noticed when she yawned that her breath is very stinky and its been over an hour or so since she's eaten. It almost smells like rotten cabbage to me. Any ideas folks? I'll have to wait until Monday to have her seen. And she hasn't seemed to grow very much since I've had her. Used to being able to notice growth in kittens this age.

Bad Breath

My cat just started to have Poopie bad breath. I also noticed that the fur at the base of her tail isn't as clean and her fur looks oily and it almost looks like she has dandruff. It also seems to be sore in some spots. She doesn't have any other symptoms other than the bad breath and poor cleaning near the base of her tail. She is chunky so could it be that she can't reach that area? I'm concerned and love my Tillie, but I want the bad breath gone and as far as her tail, I brush her and try and clean it for her. Any advice would be appreciated and very helpful!

My 10yo cat has started having extremely bad breath, seems to be losing weight, and her fur has changed to kind of oily. I don’t really have the money to take her to the vet right now but I love my cat and will do whatever I have to for her. I read a post on here that someone was giving their cat soft food and lysine. I have lysine leftover from another cat and it’s still within the use by date. I guess I could try giving her them for a couple days or so to see if it helps.

Slight Smell To Breath

My 7 year old cat started sneezing one day and developed a hard swallow, he was gulping every few minutes. He was taken to the vet who said he had a possible irritation to the pharynx so he was prescribed with Loxicom to help with anti-inflammatory to see if this helped it disappear. Well its been 9 days and it has improved as he only does it every now and then, but today he started sneezing/slight cough and then swallowing, not all the time but it isn't going away. He is going back to the vet on Tuesday but I am concerned I should take him sooner? Any advice would be appreciated as I don't want him to suffer.
