My kitten has been sneezing constantly for a month or so now.  Right
after she got her first set of shots.  There is always yellowish mucus
coming out of her nose when she sneezes.  She has no other symptoms
other then sneezing.  She eats healthy, nothing wrong with her bowels,
plays very actively with her sister, and she sleeps her normal
routine.  She is constantly wanted her nose rubbed also.  When she
sneezes a lot she looks a little miserable but for the most part she
doesn't act like it bothers her.  We listened to her chest and she
doesn't sound congested or weezing.  Just the sneezing.  Why?

Hello,
One of the best online sources for information on pet health is the
website of the Purina Company.

There you will find this list of articles about upper respiratory
problems in kittens:

Among these, I think you will find this one the most useful:

It would seem that your kitten has two of the symptoms listed as
typical in the two disease complexes described in this article:
sneezing and nasal discharge. Check out the article to see if she has
any of the other symptoms listed.

The article also covers the topic of vaccinations recommended for
kittens. Has your kitten had these important vaccinations?

Certainly, the best course of action is to consult a veterinarian, but
if you would like to pose a specific question to the experts before
you do so, the Purina site allows you to do this as well:

May your kitten's health improve!

Hi gjaeanne,

Congratulations on your new addition.  

Please have your kitten seen by her veterinarian.  

She could have cat-flu or some other illness.  Allergy to food, litter
brand or dust from the litter, cigarette smoke, pollens, sprays,
carpet deodorizers and other household products cause the symptoms you
described.

The list is endless as to *what* could be wrong, and only her vet can
diagnose and treat.

Best of luck to you,
tlspiegel

Q: We listened to her chest and she doesn't sound congested or weezing.   Why?

A: The reason that you listened to her chest was to check to see how
her breathing sounded.

Is that right?

Oh dear, this could be serious.  I don't want to scare anyone, but
Feline Rhinotracheitis or Cat Flu (as it is sometimes called) can be
serious with young kittens.  Possibly your kitten caught it at the
vets when getting the shots.

PLEASE take this kitten back to the vets .. even if symptoms have lessened.
