Here's a breakdown:
* Lifespan: Cats generally live for 12-15 years, while humans can live for 70-80 years or more. This makes it seem like cats age faster, but it's simply a difference in overall lifespan.
* Developmental Stages: Cats reach maturity much faster than humans. They reach sexual maturity around 6 months, while humans take 10-15 years. This makes their early years seem like they are aging quickly, but it's just a faster development timeline.
* Different Aging Processes: While both humans and cats experience similar aging processes, there are differences. For example, cats often show signs of aging in their teeth, bones, and muscles earlier than humans.
Why the difference?
There are several factors contributing to the difference in lifespan and aging:
* Evolutionary Pressure: Cats have evolved to live fast, reproduce quickly, and be adaptable to changing environments. This leads to shorter lifespans and faster development.
* Metabolism: Cats have a higher metabolism than humans, which may contribute to faster aging.
* Size and Weight: Smaller animals tend to have shorter lifespans than larger animals. This is a general biological principle.
Important Note: While cats age differently than humans, it's important to remember that every cat is an individual. Their lifespan and aging process can be affected by factors such as breed, diet, lifestyle, and overall health.
