Amur Ezra, Siberian Cat In The Winter

Most breeders, enthusiasts, organizations, main registries such as TICA and the WCF, and countries accept the color point coloration as being natural. Color point Siberians are also known as "Neva-Masquerade": Neva for the river where they are said to have originated, and masquerade, for the mask-like coloration.
Siberian cats moult once or twice a year. The first moult is at the end of winter. The winter moult is instigated not by a change in temperature but by a change in day length. Many Siberians will experience a less intense "mini moult" at the end of the summer season.
• Reproduction
Siberian cats tend to come into reproductive readiness earlier than other breeds, sometimes as young as five months. It is thought that this is related to the breed's closeness to its natural wild state. Feral cats often die young due to harsher natural conditions. Achieving reproductive ability early and having large litters provides a biological balance to this. On average, a Siberian litter consists of five to six kittens, as compared to the average litter of three to four kittens in breeds who have been registered as pedigreed cats. However, Siberian litters may consist of as few as one and as many as nine kittens.
