What is the average cat lifespan?

The average lifespan of a cat is around 15 years.

The average cat lifespan has increased over the past four decades. In 1980, cats only lived an average of around 7 years. As pet owners have become more aware of feline needs and vet care is more common for cats of all types, those numbers have steadily increased.

How long do indoor cats live?

Indoor cats have the longest average lifespan at 13 to 17 years. Indoor-outdoor cats may also lead long lives depending on their diet and whether they receive regular veterinarian care.

How long do outdoor cats live?

Outdoor cats only live an average of 2 to 5 years, though some pet cats that are left outside may live longer.

Outdoor cats are at greater risk of many life-threatening injuries and illnesses. That includes getting injured in traffic, having parasites, ingesting harmful substances, or being attacked by another animal. Cats that live primarily outdoors are also exposed to the elements, which can shorten their lifespans.

Each breed of cat has a different median lifespan.

Here’s a look at some popular breeds and how long they live, on average, when well-cared for as indoor cats:

Spay or neuter your cat.

Male cats live as much as 62% longer when they have been neutered. Female cats live as much as 39% longer when they’ve been spayed. Unless you have a specific plan to breed your cat with professional assistance, taking this step is one of the best things you can do for their longevity.

If you do choose to seek regular vet care, as mentioned in the first step, we recommend taking out a cat insurance policy to help cover the cost.

How old are cats in human years?

To better understand the lifespan of a cat and appreciate age-related conditions cats may have, it can be good to compare your pet’s age to the equivalent in human years.

Each cat year is equivalent to many human years. The first 2 years of a cat’s life each account for around 12 human years. That means a cat that’s 1.5 years old is like a teenager. After the first 2 years, a year in a cat’s life is like 4 years in a human life.

Check out the table below to see how old your cat is in human years.
