Can a cat catch a cold from a human? Generally, cats do not catch the common colds that humans get. However, cats can get their own set of respiratory illnesses that mimic cold symptoms. These are often referred to as “cat colds” or more accurately, feline respiratory infections.
The familiar scenario of a sneezy, sniffly pet doesn’t exclusively belong to humans. Our feline companions can also experience their own versions of the common cold, scientifically known as feline respiratory infections. These ailments are incredibly common in cats and can range from mild discomfort to severe illness, depending on the underlying cause. So, how does a cat catch a cold, and what are the common culprits behind those tell-tale cat sniffles?

Fathoming the Transmission of Feline Respiratory Illnesses
A cat catches a cold primarily through direct contact with infected cats or by coming into contact with contaminated environments. The transmission pathways are surprisingly similar to how humans spread their own respiratory viruses.
Direct Contact: The Most Common Route
Imagine two cats playing together, grooming each other, or even just sharing the same living space. If one cat is shedding a cat virus transmission agent, the other cat can easily become infected. This close proximity allows for the direct transfer of virus particles through:
- Saliva: Sneezing, coughing, or even just breathing can expel tiny droplets containing the virus. When cats groom each other, lick faces, or share food and water bowls, these droplets can be transferred.
- Nasal Secretions: The same respiratory droplets that carry viruses can also be present in nasal discharge. A cat rubbing its face against a surface or another cat can leave behind these infectious particles.
- Eye Secretions: Certain feline respiratory pathogens can also be present in eye discharge.
This is why cats that live in close quarters, such as shelters, catteries, or multi-cat households, are at a higher risk of contracting these infections. The constant interaction creates a fertile ground for viruses to spread.
Indirect Contact: The Unseen Threat
Even without direct interaction, a cat can still contract a respiratory infection. This happens through indirect contact with contaminated objects or environments. Think of it like us touching a doorknob that an infected person touched and then touching our eyes or nose. For cats, this can occur through:
- Contaminated Surfaces: Viruses can survive for a period on surfaces like food bowls, water dishes, bedding, toys, and even furniture. If an infected cat has been in contact with these items, the virus can remain viable. A healthy cat that then interacts with these contaminated items can become infected.
- Airborne Droplets: Even after an infected cat has coughed or sneezed, virus particles can linger in the air for a short time. When a susceptible cat breathes this air, the virus can enter their respiratory system.
This indirect transmission is a significant factor, especially in environments where hygiene might not be optimal or where infected cats have recently been present.
Decoding the Primary Causes: The Pathogens Behind “Cat Colds”
While we often use the term “cold,” feline respiratory infections are typically caused by specific viruses and, less commonly, bacteria. Understanding these culprits is key to comprehending how cats get sick.
The Viral Villains
Viruses are the most frequent instigators of feline respiratory disease. Two of the most common culprits are:
1. Feline Herpesvirus (FHV-1)
Also known as feline viral rhinotracheitis, this is one of the most prevalent causes of upper respiratory infection cats. FHV-1 is highly contagious and affects the upper respiratory tract and eyes.
- How it Spreads: FHV-1 spreads rapidly through direct contact with infected nasal or eye secretions. It can also be transmitted indirectly through contaminated objects and airborne droplets.
- Key Characteristics: Cats infected with FHV-1 often show a wide range of symptoms, from mild sneezing and cat nasal discharge to more severe eye inflammation (cat conjunctivitis) and even pneumonia. A significant characteristic of FHV-1 is its ability to become latent. This means the virus can remain dormant in the cat’s body for life, reactivating during times of stress, such as moving to a new home, visiting the vet, or the presence of other illnesses. When reactivated, the cat can shed the virus again, potentially infecting other cats, even if they don’t show outward signs of illness themselves.
2. Feline Calicivirus (FCV)
FCV is another major player in the world of feline respiratory diseases. It’s a highly variable virus, meaning different strains can cause different symptoms.
- How it Spreads: Similar to FHV-1, FCV spreads through direct contact with infected cats’ saliva, nasal secretions, and even urine. It can also be transmitted indirectly via contaminated bowls, bedding, and hands.
- Key Characteristics: FCV infections can manifest in various ways. Many cats experience oral ulcers (sores in the mouth), tongue ulcers, and sneezing. Some strains of FCV can cause more severe illness, including limping syndrome (pain and swelling in the legs), and in rare, highly virulent cases, a systemic disease with widespread organ involvement and high mortality rates.
Bacterial Complications: The Secondary Attackers
While viruses are the primary cause, bacteria can often step in and worsen the situation. Once the respiratory tract is weakened by a viral infection, it becomes more vulnerable to secondary bacterial infections.
- Common Bacterial Culprits: Chlamydophila felis and Bordetella bronchiseptica are common bacterial pathogens that can cause or complicate feline respiratory infections.
- Chlamydophila felis is a common cause of cat conjunctivitis, leading to severe inflammation and discharge from the eyes.
- Bordetella bronchiseptica can cause sneezing and coughing, similar to viral symptoms, and can be particularly problematic in unvaccinated kittens or stressed cats.
- How They Spread: Bacteria also spread through direct contact with infected secretions, as well as indirect contact with contaminated environments.
Recognizing the Signs: Common Cat Cold Symptoms
When a cat catches a respiratory infection, the symptoms can be quite noticeable. These often appear a few days after exposure to the virus or bacteria.
The Classic Symptoms
- Sneezing: Frequent and persistent cat sneezing is a hallmark symptom. This is the body’s way of trying to expel the irritants and pathogens from the nasal passages.
- Nasal Discharge (Cat Nasal Discharge): This can range from clear and watery to thick and colored (yellow or green), indicating the presence of infection and inflammation.
- Watery or Discharge from the Eyes (Cat Conjunctivitis): Redness, swelling, and discharge from the eyes are common. The discharge can be watery, or it can be thicker and pus-like.
- Coughing: While less common than sneezing, some cats may develop a cough as part of their respiratory illness.
- Congestion and Difficulty Breathing: Swollen nasal passages can make it hard for cats to breathe through their noses, leading them to breathe with their mouths open, which is unusual for cats.
- Lethargy: Infected cats often feel unwell and may become less active, sleeping more than usual.
- Loss of Appetite: Congestion in the nasal passages can impair a cat’s sense of smell, which is crucial for stimulating appetite. This can lead to decreased food intake and potential weight loss.
- Fever: An elevated body temperature is a common sign of infection as the body fights off the pathogens.
- Drooling: Oral ulcers, often associated with Feline Calicivirus, can cause pain and discomfort, leading to increased drooling.
The Severity Spectrum
It’s important to remember that cat cold symptoms can vary greatly. Some cats might only experience mild sneezing and clear nasal discharge, recovering within a week or two. Others can develop more severe symptoms, including difficulty breathing, pneumonia, and significant eye damage, requiring intensive veterinary care.
Factors Influencing a Cat’s Susceptibility
Not every cat exposed to a respiratory virus will become equally ill. Several factors play a role in a cat’s susceptibility:
Age
- Kittens: Young kittens have immature immune systems and are therefore more vulnerable to severe illness. They are also more likely to contract infections from their mothers or from the environment.
- Senior Cats: Older cats may have compromised immune systems due to age or other underlying health conditions, making them more susceptible to severe respiratory infections.
Immune Status
- Vaccination Status: While vaccines are highly effective at preventing severe disease, they don’t always prevent infection entirely. Cats that are unvaccinated or have not received booster shots are at a significantly higher risk of contracting and suffering from respiratory illnesses. Vaccines for FHV-1 and FCV are part of standard feline vaccination protocols.
- Stress: As mentioned with FHV-1, stress can trigger latent infections and weaken a cat’s immune response, making them more prone to illness. Changes in routine, new pets, moving, or even loud noises can be stressful for cats.
- Other Health Conditions: Cats with existing health problems, such as Feline Immunodeficiency Virus (FIV) or Feline Leukemia Virus (FeLV), or those undergoing treatments that suppress the immune system, are more vulnerable to respiratory infections and their complications.
Environmental Factors
- Overcrowding: High-density environments like shelters or catteries, where many cats are housed together, increase the likelihood of rapid transmission and outbreaks of respiratory diseases.
- Hygiene: Poor sanitation and inadequate cleaning practices can create environments where viruses and bacteria can thrive and be easily transmitted.
Preventing the Spread: Keeping Your Cat Healthy
Preventing feline respiratory infections is far better than treating them. A proactive approach to your cat’s health can significantly reduce their risk.
The Power of Vaccination
- Core Vaccinations: Vaccines against Feline Herpesvirus-1 (FHV-1) and Feline Calicivirus (FCV) are crucial components of routine veterinary care. These vaccinations help protect against the most common and potentially severe forms of feline viral rhinotracheitis and related illnesses.
- Booster Shots: Regular booster vaccinations are necessary to maintain immunity over time. Your veterinarian will advise on the appropriate vaccination schedule for your cat based on their age, lifestyle, and risk factors.
Maintaining a Clean Environment
- Regular Cleaning: Clean and disinfect food and water bowls daily. Regularly wash bedding and clean litter boxes to minimize the presence of pathogens.
- Air Quality: Ensure good ventilation in your home. Avoid using air fresheners or diffusers that emit strong scents, as these can irritate a cat’s sensitive respiratory system.
Stress Reduction
- Stable Environment: Provide a stable and predictable environment for your cat. Minimize sudden changes in routine or living conditions whenever possible.
- Enrichment: Offer plenty of opportunities for play, mental stimulation, and safe hiding places. This helps reduce stress and anxiety.
- Introduce New Pets Gradually: If introducing a new pet, do so slowly and gradually to allow your existing cat to adjust.
Quarantine New Arrivals
- Isolation Period: If you bring a new cat or kitten into your home, it’s highly recommended to keep them isolated from your existing pets for at least two weeks. During this time, observe them for any signs of illness and have them examined by a veterinarian. This quarantine period helps prevent the introduction of contagious diseases.
Good Nutrition and Overall Health
- Balanced Diet: Feeding your cat a high-quality, balanced diet supports a strong immune system.
- Regular Vet Check-ups: Annual or semi-annual veterinary check-ups allow your vet to monitor your cat’s health, detect potential issues early, and provide preventative care advice.
When to Seek Veterinary Attention
While many mild cases of cat sniffles can resolve on their own, it’s crucial to know when to seek professional help. Contact your veterinarian if you observe any of the following:
- Difficulty breathing or wheezing.
- Severe lethargy or weakness.
- Green or yellow nasal or eye discharge.
- Cloudy or ulcerated eyes, or significant eye pain.
- Refusal to eat or drink for more than 24 hours.
- Development of oral ulcers.
- Symptoms that worsen or do not improve after a few days.
- For kittens, any signs of respiratory distress.
Treatment Approaches for Feline Respiratory Infections
The treatment for a cat with a respiratory infection will depend on the specific cause and the severity of the symptoms.
Supportive Care
Often, the cornerstone of treatment involves supportive care to help the cat’s body fight the infection. This can include:
- Maintaining Hydration: Ensuring the cat has access to fresh water and encouraging drinking.
- Nutritional Support: Warming up food to enhance its aroma and make it more appealing, or hand-feeding if the cat is too weak to eat on its own.
- Keeping Nostrils Clear: Gently wiping away nasal discharge with a warm, damp cloth to help the cat breathe more easily.
- Humidification: Placing the cat in a steamy bathroom for 10-15 minutes a couple of times a day can help loosen mucus and ease congestion.
Medications
Depending on the diagnosis, your veterinarian may prescribe various medications:
- Antibiotics: These are used to treat secondary bacterial infections that may have developed. Antibiotics are not effective against viral infections.
- Antiviral Medications: In some cases, your vet might prescribe antiviral medications, although these are not commonly used for routine feline respiratory infections.
- Eye Medications: For cat conjunctivitis or other eye issues, antibiotic or anti-inflammatory eye drops or ointments may be prescribed.
- Decongestants or Expectorants: While less common in veterinary medicine for cats, some medications might be used off-label to help manage severe congestion.
Hospitalization
In severe cases, hospitalization may be necessary. This allows for intensive care, including:
- Intravenous (IV) fluids for dehydration.
- Oxygen therapy for cats with severe breathing difficulties.
- Nebulization to deliver medications directly into the airways.
- Nutritional support through feeding tubes if necessary.
The Long-Term Outlook
Most cats with mild to moderate feline respiratory infections recover fully with appropriate care. However, some cats, particularly those infected with FHV-1, may experience recurring flare-ups throughout their lives, especially during stressful periods. Chronic low-grade symptoms, such as occasional sneezing or mild eye discharge, can persist.
Frequently Asked Questions (FAQ)
Q1: Can my cat give me a cold?
A1: Generally, no. The common colds that humans get are caused by human rhinoviruses, and cats do not typically contract these. Conversely, while cats can get their own respiratory infections, these are usually specific to felines and not transmissible to humans.
Q2: How long does a “cat cold” last?
A2: The duration varies depending on the cause and the cat’s overall health. Mild infections may clear up within 7-10 days, while more severe or complicated cases can last for several weeks or even recur.
Q3: Is it safe for my cat to go outside if they have a cold?
A3: It is best to keep a cat with respiratory symptoms indoors. This prevents them from potentially spreading their illness to other cats in the neighborhood and protects them from further exposure to environmental irritants or other pathogens.
Q4: How can I prevent my cat from catching a cold?
A4: Prevention is key. Ensure your cat is up-to-date on vaccinations, maintain good hygiene in their living environment, reduce stress, and provide a balanced diet to support their immune system. Quarantining new cats before introducing them to resident pets is also vital.
Q5: What is the difference between a cat cold and feline influenza?
A5: While both affect the respiratory system, “cat cold” is a general term for upper respiratory infection cats, often caused by viruses like FHV-1 and FCV. Feline influenza, or “cat flu,” is typically a more severe illness caused by specific influenza viruses, which can lead to more rapid onset and more severe symptoms.
By comprehending the ways cats contract respiratory infections and recognizing the signs, cat owners can take essential steps to protect their beloved companions and ensure they receive prompt and appropriate veterinary care when needed.
