How Long Do Savannah Cats Live? Average Lifespan, Data & Care

Savannah cats are beautiful hybrid spotted cats with long legs and distinctive, large ears. The hind legs are usually just a bit longer than the front legs in this breed, giving them a distinctive silhouette and gait. Savannahs are a mix between wild African servals and domestic cats. Most have brown, cream, or black fur featuring brown or black spots.

They are relatively large animals, often weighing around 12–20 pounds, although some larger males can reach a whopping 30 pounds. These energetic, fun-loving cats are incredibly social and do well in environments where they interact with active people.

They’re smart and highly athletic, requiring plenty of mental and physical stimulation. Savannah cats are relatively healthy, with most living anywhere from 12 to 15 years, although several cats survive well into their 20s.

What’s the Average Lifespan of a Savannah Cat?

The average Savannah cat lives for 12–15 years. However, the breed is known for longevity, with some Savannahs living for 20 or more years. While the breed is more likely to suffer from diseases such as cancer, hypertrophic cardiomyopathy (HCM), and progressive retinal atrophy, most Savannahs are healthy and live long, happy lives.

The 3 Likely Reasons Why Some Savannah Cats Live Longer Than Others

How long any cat lives is primarily up to chance, but certain factors clearly make a difference in feline longevity, including nutrition, environment, and whether or not the cat suffers from any hereditary health conditions. Read on for more information about factors that can impact a Savannah cat’s lifespan.

1. Nutrition

Savannah cats require high-quality food to thrive. As obligate carnivores, they can only obtain all the nutrients they require by consuming food derived from animal sources. Adult cats require a diet high in protein that meets the animal’s fat and calorie needs.

Most require around 200–290 calories per day to maintain their weight, but larger cats will require substantially more. Because of their athletic abilities, most Savannah cats do better when eating high-protein meals. Look for products with a whole protein, such as chicken or duck, listed first on the ingredient list.

2. Indoor or Outdoor

There’s a significant difference in lifespan between indoor and outdoor cats. Indoor cats often live 15–17 years, but the average outdoor cat seldom makes it past 5. Outdoor cats tend to live much shorter lives due to exposure to dangers such as cars and diseases like feline leukemia.

Outdoor cats are also at heightened risk of being injured in fights with dogs and wild animals such as raccoons. Indoor cats require extra exercise and mental stimulation to make up for not being able to go outside, but it’s possible to find solutions, like food puzzles and cat trees, to keep them engaged, happy and healthy.

3. Weight

Feline obesity is a huge problem—nearly 60% of domestic cats in the United States have a severe weight problem. Obesity is directly related to a heightened risk of developing conditions such as osteoarthritis, bladder stones, and diabetes.

Most cat food packaging has explicit information about portion size to make it simple for pet owners to provide their furry friends with just the right amount of food. While most Savannah cats tend to be relatively lean, just like cats, they often put on a few pounds as they slow down with age. Senior formulations usually contain fewer calories to ensure cats maintain a healthy weight as their activity levels decline with age.

The 5 Life Stages of a Savannah Cat

1. Gestation

After fertilization, Savannah cat pregnancies last 63–65 days. Queens can have up to 5 liters per year. The average litter size comes in around four kittens.

2. Kitten

Kittens develop with lightning speed. They’re born blind and unable to walk on their own, but within a few short weeks, they’re coordinated, energetic, and engaged in exploring the world.

3. Young Adult

Most cats reach sexual maturity around 6 months of age. Unless spayed or neutered, cats at this stage are fully capable of reproducing. Unneutered younger male cats are often inclined to spray and get into fights. And female unspayed cats in heat can be needy and tend to engage in excessive vocalization.

4. Mature Adult

While the average cat is fully grown by the time they reach 1 year old, with Savannah cats, adolescence lasts much longer. These cats typically need 3 full years to reach their adult size.

5. Senior

Most veterinarians consider kitties over 11 to be seniors. Although some people break that down further and consider cats over 15 to be “geriatric.” Older cats often begin losing weight and slowing down. Chronic diseases such as diabetes, high blood pressure, and arthritis become common, as do conditions such as chronic kidney disease.

How to Tell Your Savannah Cat’s Age in 3 Steps

While it’s relatively easy to tell kittens from adult cats, it’s often a bit more difficult to pin down feline ages more precisely. Characteristics to look for as clues include weight, eye health, and teeth condition. A veterinarian may be able to narrow things down into more precise age ranges. Keep reading for a few tips on determining a Savannah cat’s age.

1. Weight

Cats only weigh a few ounces when they’re born. They rapidly gain weight during their first few months of life. While most cats are fully grown by their first birthday, it takes Savannah cats close to 3 years to reach their full adult dimensions. Adult savannah cats tend to weigh 12–20 pounds. Savannah cats heavier than around 12 pounds are most likely mature.

2. Eye Condition

Kittens and young adult cats tend to have clear eyes. Cats over the age of 10 sometimes have cloudy eyes or a noticeable ocular discharge. And some older cats develop a sort of edge around the iris. Eye clouding and evidence of ocular discharge suggest a cat is more than 10 years old.

3. Teeth

Kittens lose their baby teeth over time, but most are gone by the time cats reach 6 months old. Cats that still have baby teeth are usually relatively young. The amount of tartar on a cat’s teeth can also provide information about the animal’s age. Heavy tartar build-up often indicates an older cat.

Savannah cats are gorgeous spotted hybrid kitties with long legs, big ears, and sweet, curious personalities. Specifically, they’re domestic–African serval mixes with the markings of their wild ancestors and the personalities of tame domestic cats.

The International Cat Association granted Savannahs recognition in 2000. They tend to be healthy and often live to be more than 20 years old. Savannahs are incredibly athletic with high-activity needs. They love spending time around people and prefer company to being left alone.
