Average lifespan of a cat and how to increase it

In this post you will learn about: average lifespan of a cat. Cats are so much more than pets. They are life companions and confidants. Unfortunately, they do not live as long as humans and a lifetime for them can be too short a time for us. So, what is average lifespan of a cat? While we might not want to think about the demise of our fluffy friends, it is an important question that can help us have realistic expectations of our life with them. Cats face many environmental dangers that could potentially end their lives early.

So, What is average lifespan of a cat?

Taking factors such as genetics, disease and injury into account, the average of a cat is approximately 15 to 17 years. It is possible for cats to live into their twenties, however, and the oldest recorded cat in the Guinness Book of Records was 38 years old. Various factors influence the longevity of your cat, and knowing how to properly care for them can not only extend their lifespan, but improve their quality of life, too. Read also: How to tell if a cat is pregnant.

Diseases that could decrease the average lifespan of a cat

Regular check-ups are vital to protecting cats from death caused treatable diseases. Vets can identify and treat diseases if they are detected early enough, but failure to do so will likely result in an early passing for your cat. These are diseases you might not realize can kill your cat:


This form of heart disease is extremely common and can only be detected when using a stethoscope or heart rate monitor. One owner says that an annual trip to the vet extended her cat’s life by 8 years when they detected a problem with her heart.


Also known as overactive thyroid disease, this is one of the most common glandular diseases in cats. Symptoms can include, but may not always be: thirst, weight loss and increased appetite. These symptoms are not always uncommon enough to be noticeable, that is why medical check-ups are vital to detecting this disease.

Kidney disease

The symptoms of this disease appear gradually, making it difficult to recognize. These symptoms are a dry coat, bad breath and weight loss. A cat owner tells of how she took her cat in to get her teeth cleaned, but routine blood tests showed that kidney disease was present. The owner stresses that veterinary checks can save your cat’s life.

Urinary crystals

Crystals can sometimes form in urine, making it difficult to pass through the urethra. If your cat struggles with urination, this could be a sign of blockage by crystals. This is not only uncomfortable, but potentially deadly. A routine check-up detected crystals in one owner’s cat before the cat suffered from its effects, saving the cat from pain.


In humans, this is known as the silent killer. And it has some effects in cats. Diabetes can decrease the average lifespan of a cat. Symptoms of this disease include weight loss, increase in appetite, frequent urination and thirst. What is frightening about this disease is that it can show no symptoms at all in certain cases. The only way to detect this life-threatening disease is through, you guessed it, regular check-ups.

Genetics can play a role in how long your cat lives. It has been found that mixed-bred cats live longer than pure-breds. Pure-bred cats have a limited gene pool that makes them more susceptible to genetic diseases. Mixed-bred cats, however, Have a wider gene pool and fewer chances of inheriting unfavourable diseases. The difference in lifespan is only a few years however. Read also: How to groom your cat.
