Cats are renowned for their acute sense of smell, which plays a crucial role in their daily lives, from detecting food to recognizing potential threats. However, like any other sensory ability, a cat’s sense of smell can be affected by various factors, leading to a decline or even loss of this vital sense. In this article, we will delve into the world of feline olfaction, exploring how cats smell, what can cause them to lose their sense of smell, and the potential implications of such a loss.
How Cats Smell
The sense of smell in cats is mediated by the olfactory system, which consists of the nose, the olfactory epithelium, and the brain. The olfactory epithelium, located in the nasal cavity, contains specialized cells called olfactory receptors that are responsible for detecting odor molecules. These receptors are embedded in the mucous membrane and are bathed in a layer of mucus that helps to trap and dissolve odor molecules, allowing them to bind to the receptors. When an odor molecule binds to an olfactory receptor, it triggers a signal that is transmitted to the brain, where it is interpreted as a specific smell.
The Importance of Smell in Cats
Smell is essential for cats, as it helps them to navigate their environment, find food, and detect potential threats. A cat’s sense of smell is estimated to be 14 times more sensitive than that of humans, allowing them to detect subtle changes in their surroundings. Cats use their sense of smell to:
- Detect pheromones, which are chemical signals that convey information about an individual’s reproductive status, dominance, or other social cues.
- Identify food and water sources.
- Recognize familiar and unfamiliar environments.
- Detect potential threats, such as other animals or obstacles.
Causes of Smell Loss in Cats
While cats are not as prone to smell loss as dogs, there are several factors that can contribute to a decline or loss of their sense of smell. These include:
Infections and inflammation of the nasal cavity or sinuses can damage the olfactory epithelium, leading to a loss of smell. Respiratory viruses, such as feline calicivirus or feline herpesvirus, can cause inflammation and congestion, which can impair a cat’s ability to smell.
Tumors in the nasal cavity or sinuses can also damage the olfactory epithelium, leading to smell loss. Lymphoma and squamous cell carcinoma are two types of cancer that can affect the nasal cavity and sinuses in cats.
Aging can also contribute to a decline in a cat’s sense of smell. As cats age, the olfactory epithelium can atrophy, leading to a decrease in the number of functional olfactory receptors.
Exposure to toxins, such as pesticides or heavy metals, can damage the olfactory epithelium and lead to smell loss.
Diagnosing Smell Loss in Cats
Diagnosing smell loss in cats can be challenging, as it requires a combination of physical examination, medical history, and diagnostic testing. A veterinarian may perform the following tests to diagnose smell loss in cats:
Physical examination: A thorough physical examination can help to identify any obvious causes of smell loss, such as nasal discharge or congestion.
Complete blood count (CBC): A CBC can help to identify any underlying infections or inflammatory conditions that may be contributing to smell loss.
Imaging studies: Radiographs (x-rays) or computed tomography (CT) scans can help to identify any tumors or other abnormalities in the nasal cavity or sinuses.
Rhinotomy: A rhinotomy, which involves the surgical exploration of the nasal cavity, can help to identify any tumors or other abnormalities that may be causing smell loss.
Treatment and Management of Smell Loss in Cats
Treatment and management of smell loss in cats depend on the underlying cause. If the cause is an infection or inflammation, antibiotics or anti-inflammatory medications may be prescribed to treat the underlying condition. If the cause is a tumor, surgery or radiation therapy may be necessary to remove the tumor.
In some cases, smell loss may be permanent, and the cat may need to rely on other senses, such as hearing or vision, to navigate its environment. Owners can help to support their cat’s other senses by:
- Providing a consistent and predictable environment.
- Using verbal cues and rewards to help the cat navigate.
- Providing a variety of toys and activities to stimulate the cat’s other senses.

Can Cats Lose Their Sense of Smell?
Cats are known for their unique sense of smell, which plays a crucial role in their daily lives. Their sense of smell helps them navigate their environment, detect food, and recognize potential threats. However, like any other sense, a cat’s sense of smell can be affected by various factors. Cats can lose their sense of smell due to several reasons, including age, illness, or injury. As cats age, their sense of smell may naturally decline, making it more challenging for them to detect scents. Additionally, certain medical conditions, such as upper respiratory infections or nasal tumors, can also impact a cat’s sense of smell.
In some cases, a cat’s sense of smell can be temporarily impaired due to a blockage in the nasal passages or sinuses. For example, if a cat has a cold or allergies, their sense of smell may be reduced until the underlying condition is treated. Moreover, exposure to strong chemicals or toxins can also damage a cat’s olfactory system, leading to a loss of smell. If you suspect that your cat has lost its sense of smell, it is essential to consult with a veterinarian to rule out any underlying medical conditions. The veterinarian can perform a physical examination, take a complete medical history, and conduct diagnostic tests to determine the cause of the loss of smell and recommend appropriate treatment.
How Do Cats Use Their Sense of Smell?
Cats use their sense of smell to gather information about their environment, and it plays a vital role in their behavior and daily activities. Their sense of smell helps them detect food, recognize potential mates, and identify potential threats or dangers. Cats have a unique organ called the vomeronasal organ, also known as the Jacobson’s organ, which is located in the nasal cavity and is responsible for detecting pheromones. Pheromones are chemical signals that provide information about an individual cat’s reproductive status, dominance, or other social cues. By using their sense of smell, cats can detect these pheromones and respond accordingly.
In addition to detecting pheromones, cats use their sense of smell to explore their environment and detect hidden food sources. They have a highly developed sense of smell that allows them to detect subtle changes in their surroundings, which helps them navigate and hunt. Cats also use their sense of smell to recognize familiar scents, such as the smell of their owners or other pets in the household. This recognition of familiar scents helps them feel secure and comfortable in their environment. By understanding how cats use their sense of smell, owners can appreciate the importance of providing a stimulating and engaging environment that caters to their feline companion’s unique sensory needs.
What Are the Signs of a Cat Losing Its Sense of Smell?
If a cat is losing its sense of smell, it may exhibit several signs that indicate a problem.

How Do Older Cats Compensate for a Decline in Their Sense of Smell?
As cats age, their sense of smell may naturally decline, making it more challenging for them to detect scents. However, older cats have developed ways to compensate for this decline. One way they compensate is by relying more heavily on their other senses, such as their sense of hearing and vision. Older cats may also use their memory and past experiences to navigate their environment and recognize familiar scents. For example, they may use visual cues to recognize food or familiar objects, rather than relying solely on their sense of smell.
In addition to relying on their other senses, older cats may also adjust their behavior to compensate for a decline in their sense of smell. For example, they may become more cautious and hesitant when exploring new environments or approaching new objects. They may also rely more heavily on their owners for guidance and support, as they may have difficulty detecting and responding to their environment. By understanding how older cats compensate for a decline in their sense of smell, owners can provide a supportive and accommodating environment that meets their changing needs and supports their overall health and well-being.
Can a Cat’s Sense of Smell Be Affected by Its Diet?
A cat’s diet can play a role in maintaining its sense of smell. A balanced and nutritious diet that includes essential nutrients, such as omega-3 fatty acids, vitamin A, and zinc, can help support the health of the olfactory system. These nutrients are important for maintaining the health and function of the olfactory receptors and the nervous system that processes sensory information. A diet that is deficient in these nutrients may contribute to a decline in a cat’s sense of smell.
In addition to providing essential nutrients, a cat’s diet can also affect its sense of smell by reducing inflammation and oxidative stress in the body. A diet that is high in antioxidants and anti-inflammatory compounds can help reduce inflammation and oxidative stress, which can damage the olfactory system and impair a cat’s sense of smell. Some foods, such as those containing omega-3 fatty acids, may also have anti-inflammatory properties that can help support the health of the olfactory system. By feeding a balanced and nutritious diet, owners can help support their cat’s sense of smell and overall health.
