DURING SICKNESS

A sick animal often has a dull and patchy hair coat, because the skin is one of the first systems to be affected by disease. Another sign of illness is a lack of appetite. Persistent and severe vomiting (with or without diarrhea) and prolonged diarrhea alone are sure signs of illness. Red, watery eyes, which may be accompanied by nasal discharge or sneezing, also can indicate problems. Straining to urinate, bloody urine, or frequent urination signify disease. Any swelling that appears rapidly or continues to increase in size over time is a cause for concern. Injuries such as those caused by car accidents, falls, being bitten by another animal, or being shut in the door are all potential hazards for cats and usually require veterinary treatment. Those injuries can be greatly reduced by keeping your cat indoors. If you want your cat to enjoy the outdoors, train it to a harness and leash.
In short, use good judgment regarding your cat's health. When in doubt, a simple telephone call to the veterinarian can usually determine if your cat should be examined.
