Siberian

The Siberian is a native forest cat breed that developed over centuries in the subarctic climate of Russia.

Records referencing the landrace date to approximately 1000 AD, and the cat features in traditional Russian folktales. Modern pedigree breeding started in Saint Petersburg and Moscow during the late 1980s, followed by the first exports to North America in 1990. TICA recognized the Siberian for championship status in 1996, FIFe accepted the breed in 1997, and the CFA granted full championship standing in 2006. Full physical development proceeds at an unhurried rate, with cats taking up to five years to reach full maturity. Males reach a weight of 6-10 kg (13-22 lb), and females weigh 3.5-6 kg (8-13 lb). The body displays a firm, barrel-shaped torso with heavy bone structure. Hind legs stand slightly longer than front limbs, creating a gentle arch along the spine and providing substantial jumping propulsion.

Survival in freezing winters produced a dense triple coat with water-resistant guard hairs, awn hairs, and a downy undercoat. A full ruff encircles the neck, and tufts of fur protect the spaces between the toe pads. Standard descriptions note a calm, inquisitive, and affectionate nature, with many cats retaining playful tendencies and an unusual interest in running water. Grooming calls for combing the coat once or twice weekly to remove dead hairs and avert mats, though shedding increases during seasonal molts in spring and autumn.

This hardy breed experiences few inherited disorders, yet specific genetic illnesses do occur. Hypertrophic cardiomyopathy causes abnormal thickening of the ventricular heart walls and impairs cardiac output. Pyruvate kinase deficiency leads to erythrocyte destruction, creating hemolytic anemia that manifests as lethargy and weakness. Instances of polycystic kidney disease cause fluid-filled cysts to grow within the renal parenchyma, progressively diminishing kidney filtration. In addition, congenital sensorineural deafness appears in some solid white individuals, and hip dysplasia occasionally affects the rear joints of heavier cats.
