Cats are adorable companions that bring joy to many people. However, adopting a cat is not just a temporary fun thing. Cats require lifelong care, which can last from 12 to 20 years, depending on how well they are cared for and their environment.

How long do cats live with us?

Cats that receive good care generally have an average lifespan of about 12-15 years, and some may live up to 18-20 years. But stray cats or those without close care usually have an average lifespan of only 4-7 years because they face more dangers and risks.

Let’s compare cat ages to human ages for easier understanding:

Cats grow quickly in their first years and reach adulthood fast, so they need proper care right from the start.

Things to consider before adopting a cat:

  • Do you have enough time for them?
    Cats need playtime, care, and attention just like any other family member.
  • Are you ready to care for them throughout their life?
    From tiny kittens to senior cats, they may need different health care at different stages.
  • Can you prepare for the expenses?
    Typical yearly costs might be:
    • Cat food: 6,000 - 12,000 THB
    • Cat litter: 3,000 - 5,000 THB
    • Vet and vaccinations: 2,000 - 5,000 THB
    • Toys and equipment: 1,000 - 3,000 THB
    • Spaying/neutering (one-time): 800 - 4,000 THB
  • Totaling approximately 12,000 - 25,000 THB per year, or more depending on care.

Owning a cat means taking responsibility for a life that needs love, attention, and readiness in time and resources. If you are prepared to care for them through every stage, cats will become true friends that beautifully enrich your life.
