Average Life Expectancy Of A Cat

Average Life Expectancy Of A Cat


If you’re like me, you want your cat to live as long as possible. And while it’s up to genetics, food, and exercise how long your cat lives, there are many things we can do to help the process along. Life expectancy statistics can be useful because they show us that our decisions are having an impact on how long our cats live. In this article, I’ll discuss two types of life spans: the average life span of a cat and what we can do to make sure that they get the most out of their lives (and ours).

What is life expectancy?

Life expectancy is the average age to which a person can expect to live if they maintain their current lifestyle and health. Factors that affect life expectancy include genetics, lifestyle choices such as diet and exercise, access to healthcare, and income.

  • For example, a woman who smokes two packs of cigarettes per day has a lower life expectancy than an otherwise similar woman who doesn’t smoke at all.
  • Life expectancies vary by factors such as gender, ethnicity and socioeconomic status. Life expectancy increases with each year of age until about age 35; after this point it begins to decrease for most people.

At birth….

The average life expectancy of a cat is 12-15 years. Most cats are healthy at birth, and the average weight of a newborn kitten is 3-4lbs. At birth, they can be as long as 12 inches (30cm). The average length of a newborn kitten is 3 inches (8 cm).

Average life expectancy of a cat…

It is important to note that the average life expectancy of a cat depends on several factors, including its breed, health, environment and lifestyle.

The average life span of an outdoor cat is around 4-7 years while an indoor cat will live between 10-15 years (or even longer).

This information can help you plan for your pet’s future longevity and make sure it has the right food items available when they need them.

What affects a cat’s life span?

  • Genetics.
  • Nutrition.
  • Diet.
  • Exercise.
  • Stress levels and lifestyle (stress can affect a cat’s immune system).
  • Medications, vaccinations, surgery or other procedures performed on a cat (the stress from these can cause illness).
  • Infections from bacteria or viruses that may be carried by the cat’s environment, such as fleas, ticks and worms; parasites that live in soil where your cat plays; fungi such as ringworm; and protozoa including Giardia lamblia (which causes diarrhea) and Toxoplasma gondii (which causes toxoplasmosis). Examples of environmental factors include heat stroke from being left in a hot car for too long; injuries from accidents involving cars or household appliances such as vacuum cleaners; parasites like fleas and ticks that bite into the skin causing irritation which leads to infection; poisons found outside like antifreeze leaking onto driveways when it gets too hot outside during summer months.”

Cats can be very long lived.

You might have seen anecdotal evidence of cats living well into their 20s, but what’s the real story? How long can cats live? The answer depends on many factors, such as:

  • Genetics
  • Diet and lifestyle habits
  • Health care
  • General happiness and quality of life


Hopefully, you now have a better idea of the factors that influence how long your cat will live. As you can see, their age isn’t the only element that goes into determining this number. Instead, there are many things to consider when it comes down to it—but overall, there’s one thing we do know for sure: your furry friend is going to be with you for a long time if they stay in good health! Now go snuggle up with them and enjoy every second of the journey!
