Fatigue is a symptom, rather than a sign. A symptom is something the patient feels and describes, such as a headache or dizziness, while a sign is something the doctor can detect without talking to the patient, such as a rash. Fatigue is a non-specific symptom, i.e. it may have several possible causes.
Indoor Cats. Indoor cats can live a long life, provided they're well taken care of and they're in good health. On average, indoor cats live 12 to 15 years. A cat may reach the age of 21, if he doesnât have any medical conditions and has a proper diet.
The oldest cat recorded by the Guinness Book of World Records was one called Creme Puff, who was 38 when he died, and there are stories of others living even longer lives than this. This is quite unusual though, as an average cat life span is around 15-20 years. The kitten stage of a cat's life lasts from birth until puberty, which occurs from between six to eight months old. He's then considered a young adult up to the age of six.
