(TH) “Age is not a disease.” Older or senior cats go through many of the same health changes as people do, e.g., weight loss or gain, change in appetite and behavior, inappropriate elimination, decrease in vision or hearing, hair loss, persistent coughing or gagging, joint pain, and blood circulatory changes. Alert your veterinarian to these or other changes in your cat’s health.The gradual onset of health problems in an apparently healthy cat often goes unnoticed. Once symptoms appear, the disease may be in an advanced stage and it is difficult as well as costly to diagnose and treat.
