Upper Respiratory Infection in Cats: Symptoms and Treatment


Cats can develop cold-like illnesses that affect the nose, throat, and eyes, especially after exposure to other infected cats. Some cases are mild and improve with supportive care, while others require veterinary attention.


What Is an Upper Respiratory Infection in Cats?

An Upper Respiratory Infection in Cats affects structures such as the nose, sinuses, throat, and sometimes the eyes. These infections are particularly common in shelters, boarding facilities, multi-cat households, and other environments where cats have close contact.

Viruses cause many feline respiratory infections. Common causes include:

Young kittens, older cats, and those with weaker immune defenses may be at greater risk of developing more severe symptoms.


Common Symptoms to Watch For

Symptoms may differ depending on what caused the infection and how severe it becomes. Common symptoms include:

Cats often rely heavily on their sense of smell when eating. Nasal congestion can therefore make food less appealing and may cause some cats to eat less than usual.


How Do Cats Get Respiratory Infections?

An Upper Respiratory Infection in Cats can spread through saliva and respiratory secretions released when an infected cat sneezes or coughs.

Cats may also be exposed through contaminated objects such as:

  • Food and water bowls
  • Bedding
  • Toys
  • Grooming equipment
  • Litter-area surfaces

Some viruses can remain in a cat’s body after recovery and may reactivate during periods of stress.

If you have several cats, separating a sick cat and regularly cleaning shared items may help reduce exposure.


How Is It Treated?

Your cat’s treatment plan will depend on what is causing the infection and how seriously the symptoms are affecting them.

Mild cases may primarily need supportive care. Your veterinarian may suggest keeping your cat hydrated, gently cleaning discharge from the nose and eyes, and encouraging eating.

Other treatments may include:

  • Eye medications when appropriate
  • Antibiotics when a bacterial infection is suspected
  • Fluids for dehydration
  • Medication for specific symptoms or complications
  • Nutritional support if the cat is not eating adequately

Antibiotics do not treat viral infections, so use them only when prescribed by a veterinarian.

Never give your cat human cold medicines unless your veterinarian specifically instructs you to.


Helping Your Cat Feel More Comfortable

While your cat recovers, provide a quiet, warm resting area and easy access to fresh water.

You can also try offering aromatic wet food to encourage eating when nasal congestion reduces your cat’s sense of smell.

Keeping routine parasite prevention up to date is another important part of your cat’s overall healthcare. Explore our cat flea, tick, and parasite treatments to find products suitable for your pet.

When Should You Contact a Veterinarian?

Many mild respiratory infections improve with proper care, but veterinary attention is important if your cat:

Always treat breathing difficulty as urgent.


Can Upper Respiratory Infections Be Prevented?

It may not be possible to prevent every Upper Respiratory Infection in Cats, but several measures can reduce the risk.

Keep vaccinations current based on your veterinarian’s recommendations, maintain good hygiene in multi-cat homes, clean shared bowls and bedding, and limit unnecessary contact with sick cats.

Regular veterinary examinations and appropriate preventive healthcare can also help keep your cat healthier.


Final Thoughts

Most feline respiratory infections can be managed successfully when you recognize symptoms early. Watch for changes in your cat’s breathing, appetite, eyes, and energy levels, and contact your veterinarian if symptoms become severe or don't improve.

Along with vaccination, good hygiene, proper nutrition, and regular parasite prevention, early veterinary care can help keep your cat healthy and comfortable.

Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.

After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!

Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them. I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions. After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone. Thank you very much for this mite solution. I recommend it heartily. Harry P.S. Do not tell the Canadian vets as they will outlaw your product.
