Feline upper respiratory disease is
a viral condition seen in cats of any age. The most common symptoms
seen with the cat "flu" include sneezing, sinus congestion,
and watery eyes. There is often a fever present, which results in
the cat sleeping more and eating less. The disease normally runs
its course in about 1-3 weeks time as long as there are no complications.
As is the case with influenza in
man, each of us will express a slightly different degree of symptoms
based on our unique makeup. For example, some cats will show very
little ocular symptoms but may be terribly congested and sneeze
a lot while others may show hardly any congestion at all. The fever
may go up and down during the course of the disease and thus the
behavior will do likewise. The immune system is primarily responsible
for removing the virus and usually needs approximately 7-10 days
to produce enough antibodies to overwhelm the invader unless secondary
bacteria move in. In this case additional symptoms may be seen such
as pneumonia, vomiting and/or diarrhea.
The diagnosis is usually made in
the exam room. A white blood cell count is very helpful to determine
the impact of the virus as well as the presence of secondary bacteria.
In the simplest of cases no specific treatment is recommended other
than good nursing care and observation. In the more debilitated
or complicated cases the use of antibiotics, vitamins, and more
intensive supportive care are needed. Removing other physiological
stress produces such, as exposure to cold weather, and parasites
are appropriate.
The best means to avoid this disease,
although not foolproof, is to vaccinate against it. The vaccine
is relatively safe and very effective against the worst forms of
the disease. Being old enough to remember a time before this vaccine
was perfected, I saw many kittens suffer horrible ocular ulcers
from the calici virus component. Experiences like this has made
a believer out of me in the progress of science in veterinary medicine
