Cat coryza: description, symptoms, treatment, and prevention

Coryza or "cat flu" is an unfortunately common disease in semi-stray cats, kittens, and unvaccinated adults. If your cat has the opportunity to go out and be in contact with other cats, it will be in your best interest to have it vaccinated.
But let's start by presenting coryza in more detail: what are the main symptoms and causes of this disease, and what possibilities exist in terms of treatment and prevention?

Where does coryza come from?

Coryza is a highly contagious disease similar to the flu; of viral origin, it often leads to complications, even the death of the cat, because three viruses are in fact involved in it. The first, responsible for infection of the respiratory tract and nose, is the most virulent and can be fatal if the animal is weak. The second, causing fatigue and fever is also the cause of mouth ulcers and discharge from the eyes and nose. The third, benign, however, adds to the dejection of the cat and this combination will make it all the more vulnerable to contamination by other bacteria which can lead to the appearance of pus in the corner of the eyes and in the nose.

In summary, coryza is therefore an association of viruses and bacteria, each with different effects but which will all affect the respiratory system of the cat (the resulting eye damage). Fortunately, contamination only takes place between cats, but it can be rapid.

Symptoms of cat coryza

Like the flu, coryza causes fever and severe fatigue, loss of appetite, runny nose, and chronic cough. The nasal sphere being closely linked to the eyes, the cat then also suffers from eye discharge and irritation that can degenerate into conjunctivitis, and go as far as the appearance of corneal ulcers.

In addition to these symptoms, it is not uncommon for the cat to have bad breath due to the possible presence of gingivitis which goes hand in hand with all these infections combined. The set of symptoms varies enormously depending on the viral strain involved in a particular case of coryza; the danger is that a cat with even "light" coryza will remain a carrier of the disease for several years, even if there has been a cure for the first time.

Prevention and vaccination against coryza

For coryza, vaccination is undoubtedly the best prevention – in fact, it is even the one and only. This vaccine is one of the most recommended because the contamination can take place anywhere outside, including at the veterinarian since it is a very common condition. So even if your cat does not put his nose outside, there is little reason to disdain the risk of contamination by coryza...

The vaccine is active against most of the viruses involved in the disease, including Calicivirus and the virus responsible for rhinotracheitis. Often coupled with a vaccine against certain bacteria such as Chlamydia, which generally cause complications, this vaccination is the best way to fight coryza globally. It should be done as soon as possible, especially if the kitten is destined to go out, and a reminder will take place every year.

What treatment for cat coryza?

Coryza is difficult and expensive to treat because the veterinarian will almost necessarily use antibiotics or even antivirals if the case is particularly serious. If some rare cases can be cured without these heavy treatments, there are still serious risks of complications for the health of the cat. In particular, there is a risk of necrosis of the nasal bones which can generalize to the whole body.

In any case, the immune system will be very weakened and the cat could die as a result of these complications or other illnesses. Depending on the situation, antibiotics will be given orally or by injection. The antivirals themselves will be given by the veterinarian who may have to keep the animal under observation and administer liquid food and water, sometimes in the form of an infusion or with a pipette. At home, the food will need to be chopped and very palatable, since the cat often refuses to eat
