The age-old adage “cats have nine lives” might be an exaggeration, but it’s undeniable that our feline friends possess some extraordinary abilities. One of the most intriguing aspects of cat behavior is their sense of smell, which has been observed to be incredibly keen. But can cats smell illness? This question has sparked intense curiosity among cat owners and animal lovers alike. In this article, we’ll delve into the fascinating world of feline olfaction, exploring the science behind a cat’s sense of smell and examining the evidence that suggests they may indeed be able to detect illness in their human caregivers and even in themselves.
Introduction to Feline Olfaction
Cats are known for their agility, playfulness, and independence, but their sense of smell is often overlooked as one of their most remarkable features. The feline sense of smell is 14 times more sensitive than that of humans, making them one of the most olfactory-apt creatures in the animal kingdom. But what makes their sense of smell so unique, and how does it compare to our own?
Feline Olfactory System
The feline olfactory system is composed of two main parts: the main olfactory system and the vomeronasal organ (also known as the Jacobson’s organ). The main olfactory system is responsible for detecting odor molecules in the air, while the vomeronasal organ is specialized for detecting pheromones, which are chemical signals that convey information between members of the same species. This dual system allows cats to perceive a wide range of smells, from the aroma of fresh food to the scent of a potential mate.
How Cats Perceive Smells
When a cat smells something, the odor molecules bind to specialized receptors in the nasal cavity, which then send signals to the brain. The brain interprets these signals, allowing the cat to identify the smell and respond accordingly. But cats don’t just smell with their noses; they also use their whiskers, which are highly sensitive to touch and can detect even the slightest changes in air pressure. This unique combination of olfactory and tactile senses enables cats to build a rich and detailed picture of their surroundings, including the presence of potential prey, predators, or even illness.
The Science Behind Cats Smelling Illness
So, can cats really smell illness? The answer lies in the biochemical changes that occur in the body when we’re sick. When we’re ill, our bodies produce different metabolic byproducts, such as volatile organic compounds (VOCs), which are released into the air through our breath, sweat, and other bodily secretions. These VOCs can be detected by cats, who may be able to identify the changes in our scent and respond accordingly.
Studies on Cats and Illness Detection
Several studies have investigated the ability of cats to detect illness in their human caregivers. One study found that cats were able to detect the presence of cancer in their owners, while another study suggested that cats may be able to predict seizures in people with epilepsy. While these findings are intriguing, it’s essential to note that more research is needed to fully understand the extent of a cat’s ability to detect illness.
Limitations and Future Directions
While the evidence suggests that cats may be able to smell illness, there are several limitations to consider. For example, cats may not be able to distinguish between different types of illness, and their ability to detect illness may be influenced by various factors, such as their individual personality and life experiences. Further research is needed to explore the complexities of feline olfaction and its potential applications in human health.
Practical Applications of Feline Olfaction
So, what are the practical implications of a cat’s ability to smell illness? While we can’t rely solely on our feline friends to diagnose medical conditions, cats may be able to provide valuable insights into our health. For example, if your cat is suddenly acting strangely or showing an unusual interest in a particular part of your body, it may be worth investigating further. Additionally, cats may be able to provide emotional support and comfort when we’re feeling unwell, which can have a positive impact on our mental and physical well-being.
Cats as Therapy Animals
Cats are increasingly being used as therapy animals, providing comfort and companionship to people in hospitals, nursing homes, and other settings. Their ability to smell illness may be an added benefit in these situations, allowing them to respond to the emotional and physical needs of their human caregivers. As we continue to explore the potential of feline-assisted therapy, it’s essential to consider the complex and multifaceted nature of feline olfaction.

Can cats really smell illness in their owners?
Cats are known for their extraordinary sense of smell, which is far more sensitive than that of humans. They possess up to 200 million olfactory receptors in their nasal cavity, compared to only 6 million in humans. This allows them to detect a wide range of scents, including subtle changes in their owner’s body chemistry that may indicate illness. While it is not a foolproof method, cats can detect certain diseases, such as diabetes, kidney disease, or cancer, by smelling the volatile organic compounds (VOCs) produced by the body.
The ability of cats to smell illness is often anecdotal, with many owners reporting that their cat has shown unusual behavior around them when they were sick. For example, a cat may become more affectionate or clingy, or it may avoid its owner altogether. While these behaviors can be indicative of a cat’s ability to detect illness, more research is needed to fully understand the extent of their capabilities. It is also essential to note that cats should not be relied upon as a sole means of disease detection, and any concerns about one’s health should be discussed with a medical professional.
What types of illnesses can cats detect through smell?
Cats have been reported to detect a variety of illnesses, including diabetes, kidney disease, and cancer. They can smell the changes in their owner’s body chemistry, such as the presence of ketones in the breath or urine, which are indicative of diabetes. Cats can also detect the scent of urea, which is a waste product that can accumulate in the body when the kidneys are not functioning properly. In the case of cancer, cats may be able to detect the VOCs produced by the tumor or the body’s response to the disease.
The types of illnesses that cats can detect are likely to be those that produce a strong scent or change in body odor. For example, cats may be able to detect the scent of diabetes by smelling the acetone or fruity odor on their owner’s breath. Similarly, they may be able to detect the scent of kidney disease by smelling the ammonia or urine-like odor on their owner’s skin. However, more research is needed to fully understand the range of illnesses that cats can detect and the specific scents that they use to make these detections.
How do cats use their sense of smell to detect illness?
Cats use their sense of smell to detect illness by processing the chemical cues that are present in their environment. They have a highly developed olfactory system that allows them to detect subtle changes in their owner’s body chemistry. When a cat smells its owner, it is processing a wide range of chemical information, including the scent of their skin, breath, and bodily secretions. By analyzing these chemical cues, the cat can build a picture of its owner’s health and detect any changes that may indicate illness.
The process of detecting illness through smell is complex and involves the coordination of multiple senses, including the sense of smell, vision, and hearing. Cats use their whiskers and facial expressions to gather information about their environment and to detect subtle changes in their owner’s behavior or appearance. They also use their sense of hearing to detect changes in their owner’s voice or breathing patterns, which can indicate illness or distress. By combining these different sources of information, cats can build a comprehensive picture of their owner’s health and detect illness through a range of different cues.
Can cats be trained to detect illness in their owners?
While cats have a natural ability to detect illness, it is possible to train them to be more sensitive to specific scents or changes in their owner’s behavior. For example, a cat can be trained to detect the scent of diabetes by being exposed to the scent of ketones or other chemicals that are associated with the disease. This can be done through a process of classical conditioning, where the cat is rewarded for responding to the scent or behavior. However, it is essential to note that cats should not be relied upon as a sole means of disease detection, and any concerns about one’s health should be discussed with a medical professional.
Training a cat to detect illness requires patience, consistency, and positive reinforcement. The cat should be rewarded for responding to the scent or behavior, such as with treats or praise. It is also essential to start with simple tasks, such as detecting a specific scent, and gradually build up to more complex tasks, such as detecting changes in behavior. With time and practice, a cat can be trained to detect a range of different illnesses and to provide valuable support and companionship to its owner. However, it is crucial to remember that cats are individuals, and not all cats will be suited to this type of training.
How accurate are cats at detecting illness through smell?
The accuracy of cats at detecting illness through smell is a topic of ongoing research and debate. While there are many anecdotal reports of cats detecting illness, there is limited scientific evidence to support these claims. Some studies have suggested that cats can detect certain diseases, such as diabetes or kidney disease, with a high degree of accuracy. However, other studies have found that the accuracy of cats at detecting illness is highly variable and depends on a range of different factors, including the type of disease, the severity of the symptoms, and the individual cat’s sense of smell.
Despite the limitations of the current evidence, it is clear that cats have a unique ability to detect changes in their owner’s body chemistry and behavior. With further research and training, it may be possible to develop cats as a tool for detecting illness, particularly in cases where early detection is critical. However, it is essential to approach these claims with a critical and nuanced perspective, recognizing both the potential benefits and limitations of using cats as a means of disease detection. By doing so, we can work to harness the power of the feline sense of smell to improve human health and well-being.
Can other animals detect illness through smell like cats do?
Yes, other animals, such as dogs, can also detect illness through smell. In fact, dogs have been used for many years as a tool for detecting a range of different diseases, including diabetes, epilepsy, and cancer. Like cats, dogs have a highly developed sense of smell that allows them to detect subtle changes in their owner’s body chemistry. They can be trained to detect specific scents or changes in behavior, and they have been shown to be highly accurate at detecting certain diseases.
The ability of other animals to detect illness through smell is a topic of growing interest and research. For example, studies have shown that horses, cows, and even insects can detect certain diseases through smell. This has led to the development of new technologies and methods for detecting illness, such as the use of trained animals or artificial noses that can mimic the sense of smell. While these approaches are still in their early stages, they hold great promise for improving human health and well-being, and for harnessing the power of the animal sense of smell to detect and diagnose disease.
