Savannah Cat: Size, Generations, Temperament & Care

The Savannah cat is the tallest domestic cat in the world and one of the most controversial. Its long legs, long neck, huge upright ears, and striking black-spotted coat clearly reveal its ancestor—the African serval. Known simply as the Savannah, this is a hybrid breed, so before bringing one home, it is essential to understand the differences between generations, the challenges of its wild heritage, and how local laws regulate hybrid ownership. We cover all of this in our cat breed guide profile.

The Savannah Cat – A Serval and Domestic Cat Hybrid

On April 7, 1986, breeder Judee Frank crossed a male serval with a Siamese cat, resulting in the first hybrid of this kind—a female named Savannah. She was later bred with a Turkish Angora male, and in 1989, the second generation of kittens was born. In 1996, Patrick Kelley and Joyce Sroufe drafted the breed standard and presented it to TICA. TICA registered Savannahs as a new breed in 2001, and in May 2012, granted championship status to F4 and later generations. FIFe and many European organizations do not recognize the Savannah.

Producing F1 generation kittens is incredibly difficult: a serval's pregnancy lasts about 75 days, while a domestic cat's is about 65 days, and the sex chromosomes of the two species are incompatible. Pregnancies often fail, kittens are born premature, and servals are notoriously picky about their mates, sometimes even attacking the domestic cat. Males up to the fifth generation are usually sterile, so females are primarily used for breeding.

Generations F1 to F5: The Higher the Number, the More Domestic

• F1 – one parent is a serval (about 50% serval genes). The largest, with a wild temperament; males are sterile.
• F2 – serval is a grandparent (25–37.5%).
• F3 – serval is a great-grandparent (at least 12.5%).
• F4 – the first generation TICA considers "purebred" (stud book tradition, SBT) and allows in shows.
• F5 and later – similar in size to large domestic cats; males are usually fertile.

Generations are also marked with letters A, B, C, and SBT, which indicate how many consecutive generations of parents were Savannahs. It is important to understand that while TICA recognizes SBT cats as purebred, local and state laws in the US often have a broader definition of a hybrid. Many jurisdictions heavily restrict or outright ban the ownership and breeding of early-generation hybrids (F1–F4) due to their wild ancestry. Always check your local ordinances, state laws, and homeowners insurance policies before bringing a Savannah into your home.

Tall Legs and Huge Ears Inherited From the Serval

The Savannah's appearance is shaped by its serval traits: large upright ears, a long body and legs, a wide nose, and hooded eyes. When standing, a Savannah's hindquarters are often higher than its prominent shoulders. The head is small, taller than it is wide, and the neck is long and slender. The backs of the ears feature light ocelli spots with dark borders that resemble eyes, and the tail is short with black rings and a black tip. Ideally, dark "cheetah tear" lines run from the corners of the eyes down the sides of the nose to the whiskers. An adult cat's eyes can be green, brown, gold, or a mix.

The TICA standard only allows a spotted pattern and four colors: brown spotted, silver spotted, black, and black smoke. Size depends heavily on generation and sex: F1–F2 Savannahs typically weigh 10–24 lbs, sometimes more, while later generations weigh 8–18 lbs, similar to a Maine Coon. Because of its tall and lean build, the Savannah appears much larger than its actual weight. In 2016, an F2 Savannah male set the world record for the tallest cat at 19.05 inches.

Temperament: Dog-Like Loyalty and Wild Energy

Savannahs are often described as confident, outgoing, curious, and friendly. Many possess "dog-like" traits—they will fetch thrown toys and love playing in water. Many Savannahs are completely unafraid of water and will happily jump right in. However, early-generation Savannahs, in particular, can sometimes display wild and territorial behavior; males may be aggressive and mark their territory. Litter box issues are one of the most common reasons owners surrender Savannahs to rescues.

A Savannah needs plenty of space, vertical height, and activity: tall cat trees, wall shelves, daily active play, and harness walks. Small household pets, such as rodents or birds, are not safe around them.

Ownership Restrictions in Different Regions

Because the Savannah descends from a wild predator, many regions heavily restrict their ownership. In the United States, regulations vary wildly by state, county, and city. Some states, such as Hawaii, Massachusetts, Texas, and Georgia, have strict rules or outright bans on owning certain hybrid generations. New York City completely bans Savannahs of all generations, even though New York State allows F5 and later generations. Internationally, countries like Australia and New Zealand ban their import due to threats to native wildlife, and several European nations prohibit early-generation hybrids. Always verify your local breed-specific legislation and check with your landlords or insurance providers, as many have strict policies regarding hybrid pets.

Health: HCM, PRA, and PK Deficiency

Savannahs are more prone to hypertrophic cardiomyopathy (HCM) than many other domestic breeds. The Savannah Cat Association recommends screening cats for HCM, progressive retinal atrophy (PRA), and pyruvate kinase (PK) deficiency—conditions that cause blindness and anemia, respectively. For anesthesia, Savannahs and servals can safely be given the same medications as other domestic cats. Savannahs typically live 12 to 15 years or longer.

Care: Space, Activity, and High-Quality Food

• Space. Savannahs jump incredibly high and love to observe from above, so they need sturdy, tall cat trees and safe wall shelves.
• Activity. Daily hunting games, food puzzles, trick training, and harness walks are essential.
• Litter Box. Provide several large litter boxes in different locations and be consistent with training from a young age.
• Diet. A high-quality, meat-rich diet; fresh water must always be available.
• Coat. Their short coat only needs an occasional brush to stay healthy.

What to Consider Before Getting a Savannah

First, find out the kitten's generation and ask for documentation verifying their lineage. Early-generation (F1–F3) Savannahs require significant experience and space, and their ownership is often restricted by local laws, making later-generation cats the best fit for most families. Ask the breeder for the parents' echocardiogram results and PRA/PK deficiency tests. Inquire about how the kittens are socialized and litter-trained. Keep in mind that if you travel or move, you may need to prove the cat's generation to local authorities. When looking for a reputable breeder, ensure they provide a clear contract, health guarantees, and allow you to meet the parents—never buy from a pet store or kitten mill, as we outline in our guide introduction.
