your cat needs antibiotics asap. Your cat has URI upper respiratory infection. If not treated, depending on the health and age of the cat, it could die if left untreated. Please dont wait for it to get better, if its already that bad then go to the vet, now. Good luck and give the kitty lots of love!

If you have a sick cat, seek veterinary assistance immediately. Do not wait to see if your question is answered, especially if your pet is showing signs of illness. In many cases, time is of the essence....

The only thing I can suggest is to keep him/her warm and confortable and take him/her to the vet in the morning. I saw one site that said colds can be deadly if not treated.

Respiratory Infections and the common cold in cats

Cats can get upper respiratory infections or what we call the common cold or flu. However you can not pass a human cold on to your cat and vice versa. The cat 'cold' is a completely different cup of tea. If your cat has any of the below symptoms for more than a day or two he/she probably has an upper respiratory infection.

Upper respiratory infections are extremely contagious (infection can be passed through an airborne contagion or through casual contact) and it is very common for all cats within a household to become infected quickly. Although most of the agents that cause URI do not survive very long (from a few hours to a few weeks) in the environment, they can last a very long time in the cat's respiratory tract in a latent or potent form. Many cats actually will carry the agent in their body for the duration of life. In such a case your cat may suffer from occasional flare-ups when stressed or when the immune system is weak. Such a cat may also pass the agent on to other cats (even if that cat isn't actively sick). Cats can get URI's for a variety of reasons just as people do. These reasons can range from:

A bacteria or virus (Chlamydia, Feline Calicivirus, Feline Herpes virus also known as Feline Rhinotracheitis Virus) a majority of UTI's are caused by a virus
A parasitic worm infection
An allergic reaction
Symptoms to look for:

Sneezing
Runny nose
Coughing
Wheezing
Discharge from the nose or mouth
Respiratory problems
Oral ulcers
Conjunctivitis (discharge from the eye)
