What is Coryza in cats?
Coryza, also known as feline viral rhinotracheitis or cat flu, is a common infectious disease that can be caused by three viruses and one bacterium in particular:
- Feline herpesvirus type 1 (FHV);
- Feline calicivirus (FCV);
- Reovirus;
- And the chlamydophila felis.
These four pathogens can, alone or in combination, be responsible for the development of coryza. In less frequent cases, other bacteria, such as bordetella, pasteurella and mucoplasma can also trigger it.
Cat flu is highly contagious. It is therefore usually contracted by animals living in a community: pet shops, catteries, shelters, homes or even families with several cats. Fragile animals, such as kittens, older cats and unvaccinated cats are at greater risk of exposure to coryza. It is estimated that 70% of the cat population is a carrier of the virus.
Transmission is mainly by direct contact:
- Mouth;
- Eyes;
- Nose;
- Sneezing;
- Blow of fire propelling droplets ;
- Infected discharges.
However, it can be contaminated indirectly by contact with a soiled item (hands, cloth, object, etc.). The life span of the FHV virus varies between 12 and 18 hours, depending on the degree of humidity, compared to an average of 10 days for the FCV.
Caution is called for when it comes to humans, because while feline herpes virus, calicivirus and reovirus cannot infect us, chlamydophila felis can. It can lead to chlamydia, an exceptional zoonosis that can cause flu-like symptoms, photophobia and conjunctivitis. On the other hand, feline viral rhinotracheitis poses no risk to your other pets, such as dogs.
Finally, it is important to know that coryza is a disease that persists for life in cats, in a latent form. The virus nests in the deep layers of the tonsils or in the trigeminal ganglion, which unfortunately makes it inaccessible by the animal's immune system.
What are the symptoms of coryza?
As coryza can be caused by several pathogenic entities of varying virulence, the symptoms and their severity vary according to the virus. They are generally illustrated by an attack on the respiratory tract and mucous membranes:
- Respiratory: wheezing, sneezing, coughing, runny nose, crusty nose;
- Ocular: discharges, ulcers (FHV), crusts, conjunctivitis;
- Buccal: important salivation, ulcers (FCV);
- Other: fever, exhaustion, loss of appetite, dehydration, lameness...
If you have several felines with the same symptoms, it is very likely that it is coryza because it is so contagious.
A veterinarian can diagnose the disease by observing the symptoms or via a test that will determine the pathogen(s) responsible for the disease. Be careful, the cat is not an animal that easily supports fasting. In case of suspicion, it is necessary to consult a professional if the cat has not eaten for 24 hours.
Finally, depending on the type of virus and the health conditions of the animal, recovery can be easy or difficult, leading to complications and death in the worst case.
How to treat coryza in cats?
The treatment of coryza will depend on the condition of the cat and the severity of its symptoms:
1Probe:
the feline may be hospitalized to have a catheter placed to help with feeding and hydration;
2Antibiotics:
administered in the form of tablets, drops or injections, to fight against bacterial superinfection;
3Anti-inflammatory:
used to soothe his pain;
4Antivirals:
prescribed in the most severe cases, recalcitrant, with complications;
5Hygienic care:
wipe the nasal and ocular discharge, remove the crusts which obstruct the nostrils of the animal, take care that its eyes do not remain stuck;
6Food:
Even if it does not present any more symptoms, the contagiousness remains permanent in the cats chronically contaminated by the feline calicivirus (FCV). On the other hand, it turns out to be intermittent, depending on the attacks, for cats carrying the feline herpes virus (FHV).
The incubation period for coryza is short, from 2 to 5 days before the first signs appear. If you have other felines, it is necessary to isolate the cat suspected of being infected to prevent the spread of the disease to other cats.
How to protect your cat from coryza?
Vaccination remains the most effective preventive method against the risk of contamination. Injection protects againstherpesvirus (FHV), calicivirus (FCV) and chlamydophila felis, but not other bacteria such as bordetella, pasteurella or mucoplasma.
Finally, if you have been in potential contact with a contaminated cat, you should know that the herpes virus and the calicivirus are not resistant to bleach, soda or heating to 50°C.

Hllo, We invite you to try the <a href="https://loreandscience.fr/shop/mon-chat/allergies-respiration-coryza-chat/corycat-soutien-respiratoire-coryza-chat/" target="_blank" rel="ugc">CoryCat supplement</a>, which is very easy to administer as it is put directly into the cat's food and gives excellent feedback from our users. Coryza is an infection that occurs in episodes, and there is as yet no treatment that completely eliminates the virus.

My cat has coryza - loss of appetite, sneezing, coughing, listlessness. I've tried giving it the antibiotics the vet prescribed (pill form) but the cat refuses to eat it. I don't want to stress him out by forcing it down his throat. Do you have any other suggestions? Does coryza clear up by itself after a while?

Bonjour, Une femelle atteinte du coryza peut elle le transmettre aux petits ? Ne pourra t elle plus jamais reproduire ?

Bonjour, oui nos produits ne proposent aucun effet contraire lors de la prise de médicaments.

Bonjour François, Sans pouvoir vous dire qu’il s’agit d’un Coryza avéré (diagnostic qu’un vétérinaire pourrait faire), en tout cas la symptomatie évoque bien une infection respiratoire. Le mieux serait probablement de consulter. Cordialement

Bonjour, je m appelle Nathalie. Je suis bénévole en protection animale et je m'occupe de nourrir des chats libres. Je remarque aussi des chats porteurs du virus du coryza, touchés par le calicivirus avec l' inflammation s appelant stomatite. Le chat a des difficultés à manger. Étant en contact avec une association de Protection Animale, nous prenons en charge le chat pour lui prodiguer les soins médicaux nécessaires afin de le soulager de la douleur et lui apporter un meilleur confort buccal pour qu il puisse s' alimenter. Je vous écris aujourd'hui pour savoir ce qu'il en est concernant le chat libre que vous nourrissiez. Je vois votre écrit trop tard. La chose que je vous aurais conseillé de faire est de contacter une association de Protection Animale afin de sortir ce chat malade de la rue. Soit en le prenant à la main si celui-ci est sociable ou bien le capturer à l aide d' une trappe de capture s il ne se laisse pas approcher. Ce chat est il encore vivant aujourd'hui ? Avez vous pu faire quelque chose pour lui ? Nathalie M. Nantes, décembre 2023

merci pour votre commentaire, notre produit le Corycat 100% naturel permet effectivement de soulager les symptômes du chat atteint du coryza. Malheureusement le chat restera porteur du virus du coryza toute sa vie sous forme latente, il n'y a pas pour l'instant de solution pour éradiquer le virus définitivement, il est recommandé de vacciner les chats dès le plus jeune âge, ce qui les rendra plus résistants face à ce virus.

Je donne à manger à un chat libre, que je soupçonne atteint de coryza, éternuement, toux, salivation, sifflement et très maigre depuis trois quatre mois. Je lui donne votre produit qui a l'air de lui être bénéfique. Je ne peux pas l’emmener chez le véto, que puis je faire pour le guérir?
