The Savannah is a hybrid breed that began in 1986, when an African serval was crossed with a Siamese in the United States. Cats are labeled by generation: an F1 has a serval parent, and each later generation, F2, F3, F4 and beyond, has less wild ancestry. TICA recognizes later-generation Savannahs as a domestic breed. They are tall, leggy cats with large ears, a long neck and a bold spotted coat, and early generations can be much larger than typical house cats.
Many Savannahs are intensely active, curious and attached to their people, often fetching, walking on a leash and enjoying water. Early generations can be territorial, mark with urine and be hard to handle, and some states and cities ban or restrict them. Adopters should confirm local law and plan for a great deal of enrichment.
