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.
Cat Lifespan. Your catâs expected lifespan depends on whether you allow him to roam around outdoors. If so, expect him to live for about 3 to 5 years. If heâs solely an indoors cat, he can live on average 16 years, although he might live on for a few years beyond that.
