Why does my cat’s breath smell like something died?

Hey there, fellow cat lovers. If you’ve ever been hit with the stench of your feline’s breath, which can make you feel like something has died in their mouth, then you know how unpleasant it can be. But don’t worry; you’re not alone. The question “why does my cat’s breath smell like something died?” is a common one among cat owners.

It’s crucial not to overlook bad breath in cats as it could indicate a more severe health issue. However, the primary reason behind this foul odor is pretty simple – dental problems. Just like humans, cats can experience dental issues such as gingivitis, gum disease or dental decay. Shockingly, 75% of cats over three years old are said to have some form of dental problem that leads to bacterial build-up and that infamous bad breath.

Cats who consume wet food diets are at higher risk of developing dental issues since the food sticks to their teeth and gums. Additionally, a lack of water intake can cause dehydration and contribute to your cat’s bad breath.

If you’re wondering what you can do about your cat’s smelly breath, don’t worry; we’ve got you covered. In this blog post, we’ll explore the reasons why your cat’s breath smells so terrible and discuss some effective remedies that will help keep your furry friend’s mouth fresh and healthy.

What Causes Bad Breath in Cats?

Bad breath, or halitosis, in cats is a common issue that can be caused by various factors. The most prevalent cause of bad breath in cats is poor dental hygiene. When cats eat, food particles can get trapped between their teeth and gums, leading to bacterial growth and the production of foul-smelling odors. This situation can lead to gum disease and tooth decay if not treated promptly.

Digestive problems can also cause bad breath in cats. When cats eat too quickly or consume foods they shouldn’t, they can suffer from gastrointestinal issues such as constipation or diarrhea. These problems can result in bad breath as well as other symptoms like vomiting and loss of appetite. To prevent digestive problems, it’s crucial to feed your cat a healthy diet and watch their eating habits.

Bad breath in cats could also be a symptom of underlying health issues such as kidney disease or diabetes. These conditions affect the body’s ability to filter toxins and waste products correctly, resulting in an accumulation of harmful substances that can cause bad breath. If you observe persistent bad breath in your cat, it’s crucial to take them to the vet for a comprehensive check-up.

Another cause of bad breath in cats is oral tumors or growths. These growths produce an unpleasant odor due to the breakdown of tissue and can also cause pain and difficulty eating. If you notice any unusual growths in your cat’s mouth, it’s important to take them to the vet for a proper diagnosis.

To prevent bad breath in your furry friend, it’s essential to maintain their dental hygiene by regularly brushing their teeth and providing them with dental chews or toys. Feeding them with a healthy diet and monitoring their overall health is also crucial. Regular check-ups with the vet will help identify any underlying health issues that may cause bad breath.

Dental Disease as a Cause of Bad Breath

Dental disease is one of the most frequent causes of bad breath in felines. The accumulation of bacteria and plaque in their mouth can lead to gingivitis, periodontal disease, and tooth decay. As these bacteria feed on food particles and debris, they produce an unpleasant smell that can be hard to ignore.

The repercussions of untreated dental disease go beyond bad breath- it can cause pain and discomfort for your cat and lead to more severe health issues such as infections and organ damage. To avoid these problems, it is crucial to take good care of your cat’s dental health by scheduling regular checkups with your veterinarian and providing proper dental care at home.

So, what can you do to prevent dental disease from causing bad breath in your cat?

  • Regular checkups with your veterinarian: Your vet can detect any early signs of dental disease and recommend appropriate treatment before it becomes a bigger issue.

  • Balanced diet: Feeding your cat a balanced diet that includes crunchy kibble can help keep their teeth clean.

If your cat already has dental disease, don’t fret. Your veterinarian may recommend a professional cleaning under anesthesia to remove tartar and bacteria from their teeth and gums. Antibiotics may also be prescribed to treat any infections.

Kidney Disease as a Cause of Bad Breath

If you’ve ever noticed your feline friend’s breath smelling foul, it could be a sign of kidney disease. This common condition in cats occurs when the kidneys are unable to effectively filter waste products from the blood, leading to a build-up of toxins that can cause bad breath. The odor is often described as similar to ammonia or urine, and it’s important for cat owners to be vigilant about this symptom, as it can indicate a serious underlying health problem.

In addition to bad breath, other signs of kidney disease in cats include increased urination and thirst, weight loss, lethargy, and vomiting. Left untreated, kidney disease can progress to life-threatening complications such as kidney failure. Therefore, it’s crucial for cat owners to seek veterinary care if they suspect their cat may have kidney disease or any other health problem.

To manage kidney disease in cats, special diets and medications may be necessary. With early detection and treatment, however, the cat’s quality of life can be improved and further complications prevented. Along with veterinary care, there are also preventative measures you can take to reduce the risk of kidney disease in cats, including providing a balanced diet, clean water at all times, and regular check-ups with your vet.

Indigestion as a Cause of Bad Breath

Your cat’s bad breath can be an unpleasant odor that permeates your home. Indigestion is a common culprit for this problem, and there are several reasons why it can cause bad breath in cats.

One reason is when your feline friend eats something that doesn’t agree with its digestive system. The food may not break down correctly, leading to the production of gases that cause foul odors. As an expert in this subject, I know that nobody wants their cat’s breath to smell like yesterday’s tuna.

Another reason for indigestion in cats is hairballs. Cats groom themselves frequently, and they can ingest a significant amount of hair during this process. If the hair doesn’t pass through their digestive system properly, it can accumulate and form hairballs, leading to indigestion and bad breath.

It’s important to note that indigestion can also indicate an underlying health issue. If your cat’s bad breath is accompanied by other symptoms such as vomiting or lethargy, seek medical attention from a veterinarian.

To avoid indigestion and bad breath in cats, feed them a balanced diet appropriate for their age and health condition. Fresh water is also essential to flush out toxins from their system and promote good digestion.

Regular grooming can also reduce the amount of hair your cat ingests during self-grooming, preventing hairballs and reducing the risk of indigestion.

Signs and Symptoms of Illness in Cats

Cats can be notorious for hiding their discomfort or pain, so it’s up to us to recognize any changes in their behavior or health.

One of the most telling symptoms of illness in cats is bad breath. While poor dental hygiene can certainly cause some odor, if your cat’s breath smells like something died, it could be a sign of a more serious underlying health issue. Other warning signs of illness include lethargy, loss of appetite, vomiting, diarrhea, coughing, sneezing, and changes in behavior.

If you notice any of these symptoms in your cat, it’s crucial to consult with a veterinarian. Regular check-ups are also essential for detecting any underlying health issues early on before they become more serious. It’s recommended to take your cat for a check-up at least once a year, especially as they age and become more susceptible to certain illnesses.

But what causes bad breath in cats? Some common culprits include dental issues like gum disease or tooth decay, kidney disease, or even respiratory infections. Preventing bad breath starts with maintaining good dental hygiene habits. Brushing your cat’s teeth regularly and offering dental treats can help prevent plaque buildup and keep their breath fresh.

In addition to dental hygiene, make sure your cat has a balanced diet and plenty of fresh water to prevent dehydration and digestive issues that can lead to vomiting and diarrhea. Regular grooming can also prevent hairball buildup and indigestion.

Diagnosis and Treatment Options for Bad Breath in Cats

Halitosis in cats can be indicative of underlying health concerns that demand immediate attention. In this article, we will delve into the diagnosis and treatment options for bad breath in our furry friends.

It is crucial to schedule an appointment with your veterinarian as the first step in diagnosing bad breath in cats. During the exam, the vet will check for signs of dental disease, such as tartar buildup, inflamed gums, or loose teeth. Additionally, they may also look for other indicators of illness, such as dehydration, kidney disease, or liver problems.

If the vet determines that dental disease is the cause of bad breath, they may recommend a dental cleaning procedure. This method involves removing tartar and plaque buildup from the teeth and gums. In severe cases, antibiotics may also be prescribed to treat any bacterial infection.

However, if bad breath is caused by an underlying medical condition like kidney disease, then blood and urine tests will be conducted to diagnose the condition. The vet will then prescribe appropriate treatment.

In some instances, changes to the cat’s diet or oral hygiene routine may be recommended by the vet. Feeding a high-quality diet and providing dental treats or toys can help prevent tartar buildup and keep your cat’s mouth healthy. Additionally, ensuring that their water bowl is always filled with fresh water is critical.

Regular check-ups with your veterinarian can help prevent and detect any health issues early on. Suppose you notice bad breath in your feline friend; don’t hesitate to take them to the vet for a check-up. Remember that prevention is always better than cure, so maintaining good oral hygiene habits and taking your cat for regular check-ups is vital for their overall health and well-being.

Home Remedies for Bad Breath in Cats

Fret not, as an expert in the field, I’ve compiled some research notes on effective home remedies to combat bad breath in cats.

Firstly, let’s address the root cause of bad breath in cats. Poor dental hygiene is one of the most common culprits. If your cat’s breath smells foul, it could be a result of dental disease or an infection. To tackle this issue, start by brushing your cat’s teeth regularly with a toothbrush and toothpaste specifically designed for felines. You can also add a small amount of coconut oil or dental health supplement to their food for added support.

Next up, let’s talk about parsley – a natural deodorizer that can work wonders for your cat’s breath. This herb is known for its ability to neutralize odors and can be easily incorporated into your cat’s diet. You can add fresh parsley to their food or make a tea out of it and offer it as a drink.

In addition to parsley, probiotics are another excellent remedy that can aid in improving digestion and reducing bad breath caused by digestive issues. You can give your cat probiotic supplements or include probiotic-rich foods like kefir or yogurt in their diet.

Lastly, ensure your cat is well-hydrated. Dehydration can cause bad breath, so ensure that they have access to fresh water at all times. You can also increase their water intake by incorporating wet food into their diet.

However, if your cat’s bad breath persists despite these remedies, it is critical to take them to the vet as it could be indicative of an underlying medical condition that requires professional attention.

Diet Changes to Improve Oral Hygiene

That’s right, the food you feed your cat can make all the difference in the world.

First and foremost, the quality of food your cat eats is essential. Low-quality food with artificial preservatives and coloring agents can cause digestive problems, leading to bad breath. On the other hand, high-quality wet food containing a high percentage of water helps keep your cat hydrated while also keeping their mouth moist. Dry food, on the other hand, can stick to your cat’s teeth and contribute to plaque buildup, which can lead to bad breath.

Another important factor to consider is choosing the right type of food. Food specifically formulated for dental health promotes chewing and helps remove plaque from your cat’s teeth, preventing bad breath. These foods are designed to keep your cat’s mouth healthy and fresh.

Adding fresh parsley to your cat’s diet is another simple dietary change that can positively impact their oral hygiene. This herb contains chlorophyll, which neutralizes odor-causing compounds in your cat’s mouth. Additionally, parsley is rich in antioxidants and vitamins that promote healthy digestion.


In conclusion, don’t turn a blind eye to your cat’s bad breath. Although it may seem like a minor issue, it could be an indicator of something more serious. Dental hygiene is the most common culprit behind foul feline breath, but underlying health conditions such as kidney disease or diabetes could also be to blame.

Don’t wait for your cat’s next check-up to start taking action. Regular dental care at home can make all the difference in preventing dental disease and bad breath. Brushing their teeth, providing dental treats and toys, feeding them a balanced diet, and ensuring they always have fresh water are all crucial steps in maintaining good oral hygiene for your furry friend.

If you suspect something more sinister is causing your cat’s bad breath, seek veterinary care immediately. Early detection and treatment can improve their quality of life and prevent further complications down the line.

But don’t worry – there are also several effective home remedies that can help combat bad breath in cats. From parsley to probiotics, coconut oil to supplements added to their food – there are plenty of options available to keep your cat’s mouth fresh and healthy.

Remember: prevention is always better than cure when it comes to your pet’s health.
