The first sign of your cat being unwell may be a change in its normal behavior. If your cat is normally friendly and starts to show signs of aggression then look for other signs of illness as well.

A lack of response to being called may mean a fever or a temporary deafness caused by an ear mite infestation.

Sick cat symptoms should be carefully monitored because while some may seem minor, they could be indications of more serious illness. Here is a list of some common ailments:

Sneezing or Coughing

On occasion, your cat may suffer from a respiratory illness. If your cat only sneezes occasionally, then he probably sniffed a bit of dust or other irritant.

Your cat may be suffering from a respiratory illness if your cat’s sneezing symptoms occur for a few weeks in the spring and fall, then clear up on their own after these seasons.

Shakes Head Excessively

If your cat is exhibiting this behavior, then he or she could have ear mites or an ear infection.

Discharge in Eyes

Any discharge from the eyes that is not clear in color should be a cause for concern. Discharge from the eyes in different colors, like cloudy white or green, may indicate other eye afflictions.

For example, conjunctivitis, or inflammation of the eye, will cause discharge to be secreted from the eye and requires treatment in the form of drops.

Fur or Skin is Irritated

If you notice any changes in your cat’s fur or skin, the symptoms could be of fungal and bacterial infections. These infections cause skin changes including foul odor, redness, greasiness, irritation, hair loss, rashes, pustules, and discharge.

Vomiting

Most cats have sensitive stomachs and vomit very easily, especially when they have hairballs. If your cat vomits once or twice, but continues to behave normally and shows no other symptoms, then he or she is probably suffering from a temporary case of upset stomach.

If other symptoms, such as fever, lethargy, weakness, dehydration, or diarrhea occur, then your cat should be inspected for other more serious illnesses.

Diarrhea

Most cases of diarrhea are minor and can be resolved within a few days. Minor cases of diarrhea are usually the result of intestinal yeast infections, food allergies, or food intolerances. Intestinal parasites and bacterial infections are also responsible for many cases of minor diarrhea.
