Cats can live a long time. The average lifespan of a cat is about 15 years, which means they'll often even outlive most of our pet dogs. A teenage cat, or even one in their 20s, is not uncommon to see.
Many factors can play a role in determining how long your cat might live. Regular veterinary care, a balanced diet, and a safe environment are crucial for a cat's longevity. Additionally, genetics and lifestyle can significantly impact a cat's lifespan.
Cats have been kept as pets for thousands of years. They originate from the Near East countries where they were domesticated from wild cats to help control rodent populations. These cats spread throughout the world as pets, and we eventually started selectively breeding them for specific traits, thus creating different breeds.
The primary cat breeds were originally bred using cats from four major regions; the Arabian Sea, the Eastern Mediterranean, South Asia, and Western Europe. These four regions have produced cats that have different genetic markers based on what region, or race, they are from.
While it is impossible to know exactly how long a cat will live, some breeds of cats are known to often live longer than others. The Siamese and Manx cat breeds are two that often outlive their cat competition, but other breeds have been recorded as living into their 20s and even 30s. Both purebred and domestic mixed-breed cats have the potential to surpass the average lifespan of the species.
Cats primarily eat meat, so they are considered obligate carnivores, and this should be reflected in the food we feed them. A lot of research has been done to determine the dietary needs of a house cat, so the food options that are available to cat owners are plentiful.
But not all foods are created equal. Adult cats cannot digest large amounts of carbohydrates or lactose, so these are unnecessary ingredients in their food. Carbohydrates can even decrease how much protein is digested, so they are, in fact, harmful to a cat. Proteins, on the other hand, are very important. Cats require a large amount of protein when compared to dogs due to their unique digestive system. Adult cats should receive at least 5.5 grams of protein a day per kilogram of weight. This means the average 8-pound cat (roughly 3.6 kilograms) needs to consume at least 20 grams of protein each day and often much more.
Essential amino acids are also very important to a cat. Taurine, methionine, and cystine are some of these essential amino acids, and without them, important vitamins, and the proper amount of protein, a cat’s health may suffer greatly.
Of course, a cat that doesn’t eat a healthy diet may develop health issues, but parasites and diseases can also affect their health. Some diseases have long-term effects on cats and may also shorten their lifespan.
Poor genetics, immune-compromised cats, and cats that have compromised organ functions might not live as long as healthy cats.
Some cats are considered indoor pets, others are strictly outdoor pets, and others still will be indoor/outdoor pets that split their time between environments. The daily risks that outdoor cats take are much higher than those of an indoor cat, so the lifespan of an outdoor cat is often cut short. Avoiding getting hit by vehicles, hurt by wild animals and eating toxins, finding food, surviving the elements, and being exposed to various parasites and diseases may all be daily challenges for an outdoor or indoor/outdoor cat. The more time a cat spends outside, the greater the risk is of an injury or illness from that environment.
Indoor cats are not exposed to as many risks since they are sheltered inside a secure home. Wild animals and vehicles pose no threats to an indoor cat, their diet is typically controlled, and toxin, parasite, and disease exposures are lessened, especially if they are vaccinated and on preventative medications.
The same is true for big cats like lions, tigers, ocelots, and other wild cats. These cats that reside in zoos often outlive their wild counterparts.
Guinness World Records lists the oldest cat as having lived 38 years and three days. Crème Puff was a domestic shorthair cat that was sometimes fed odd things such as asparagus, eggs, and heavy cream. She was born in 1967 and died in 2005 in Austin, Texas. It is unknown exactly how Crème Puff was able to live to be such an old cat, but a combination of loving care, good genetics, and a safe environment were probably key factors.
While we never have complete control over our cats' lives, we can be sure to offer them a safe, healthy, and loving environment to increase the odds of them living a long life.
If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
