Sharing the Natural Healing Power of Cats 


There are various distinctive landraces of domestic cat around the world, including the Aegean, Cyprus, domestic long-haired, domestic short-haired, Kellas and Sokoke, among others. Many standardized breeds have rather recently (within a century or less) been derived from landraces. Often called natural breeds, include Arabian Mau, Egyptian Mau, Korat, Kurilian Bobtail, Maine Coon, Manx, Norwegian Forest Cat, Siberian, and Thai (which is the landrace ancestor of modern Siamese cats), among many others. 

The Siberian Cat developed in a specific geographic location and possess unique appearances and personalities. The domestic Siberian bears a strong resemblance to the Middle Easter subspecies of wildcat felis silvestris caucasica and may be descended from these. The cat is an ancient breed that is now believed to be the ancestral to all modern long-haired cats. The recorded history of the Siberian dates back at least 1000 years. Like many populations of animals, the Natural Breeds of cats are at risk of disappearing. 

PCT Preservation And Conservation Breeding Program

The goal of PCT, Inc Preservation Breeding Program is to keep in the world the traits, characters, hereditary factors which make one aspect of a breed or species different from another--in short, to preserve genes for the future.

The Aboriginal Siberian Cat 

Siberian Cats Are A Russian National Treasure.

The wild cat (Felis silvestris Schreber, 1777)

The European wildcat is on average bigger and stouter than the domestic cat, has longer fur and a The European wildcat is on average bigger and stouter than the domestic cat, has longer fur and a shorter non-tapering bushy tail, it has a striped fur and a dark dorsal band. Males average a weight of 5 kg (11 lb) up to 8 kg (18 lb), and females 3.5 kg (7.7 lb). Their weight fluctuates seasonally up to 2.5 kg (5.5 lb).

They also have a less diffuse stripe pattern, proportionally larger teeth, and feed more often on rabbits than the wildcats north of the Douro-Ebro, which are more dependent on small rodents.

Since European wildcats and domestic cats interbreed, it is difficult to distinguish European wildcats and striped hybrids correctly on the basis of only morphological characters.

Felis Silvestris Caucasica (Picture taken by Russian felinologists in Armenia)

It is hardly disputable that Russian semi-longhair cats have ancient origins. For many tens of years, and probably for centuries, these cats populated Russia and received their now well-known name, Siberians long ago.

 This common name given to strong and intelligent cat with semi-longhair coat and dense triple undercoat underscores the ability of the animal to survive during cold winters in such areas as Siberia and Northern Russia.

Despite the name “Siberian”, it is unlikely, that the breed truly originated in Siberia.  

For centuries, Siberia was the country mostly populated with nomad tribes thus providing little opportunity for domestication of wildcats. There are several hypotheses regarding spread of SLH cats in Russia. The most reconcilable suggests Transcaucasia and Iran as the center of common origin of all SLH and LH cats including Siberian ancestry.  

Acquisition of long coat and pronounced undercoat by cats lived there is not surprising provided the continental climate in these areas with quite low temperatures in mountainous areas in winter. Indeed, the endemic subspecies of Transcaucasian wildcat (Felis silvestris caucasica) is very similar to a Siberian in appearance.  Sibaris RU

Aboriginal Siberian Cats   

The first standards of the new breed were created in the late 80's by the felinologists of the "Kotofei" club (O.S. Mironova, I.J. Katser, etc.). At the same time the Siberian cats were registered and bred by other Russian felinologists. In Moscow this work was being done by T.S. Emelyanova, L.K. Ovchinnikova, T.D. Sapozhnikova. But it was "Kotofei" that wrote the standard. The legendary Siberian stud Roman, born in 1987 (owner A. Ivanova, "Kotofei"), was taken as a model. He was one of the foundation cats for the breed.

The Natural Siberian Cats Breed Are In Danger of Instinction

The development of the breed placed this natural cat breed in danger of intinction. Though these cats are the national treasure of Russia, they have also given rise to the most popular Man Made cat breeds in the world. 

A Natural Breed is a breed of cat that came into existence all on its own from locally adapted varieties of cat (landraces). It developed naturally, in the case of the Aboriginal Siberian Cats, in the streets, villages, farms and mountain sides of Eastern Region of Russia (i.e.Siberia). 

These felines show a more stable genetic code than breeds created by controlled crosses between different specimens of other breeds. In general, this is expressed though greater physical resistance to disease and a lower genetic predisposition to develop numerous degenerative pathologies.

A Man Made breed is a breed that was created by cat breeders.

Siberian race and Neva-Masquerade cat- how it was

Scientific Research

Scientific research has determined that Siberian Cats are genetically distinct from cats from other parts of the world, and, anyone who has had one these cats, will attest to this fact. They are not the same as a European or Middle Eastern cat. 

There are some unpublished indications that the genome of Siberian cats contains DNA sequences uncommon in other breeds. For example, Siberians are thought to cause less allergic reactions comparing to any other cat breed. Whether it is indeed the case, remains to be investigated, but spread of foreign genes from Thai and other colorpoint-carrying cats in Siberian population can rapidly eliminate the opportunity to know if there was a real molecular mechanism behind this. 

Additional study is needed to confirm these initial findings, but if consider unrestricted breeding of Siberian cats with Neva Masquerades already containing significant proportion of non-native genetic material, the uniqueness of Siberian genome is at risk to never been described. 

Feline Allergen (Fel-d1)

Large scale research has shown that all cats produce some feline allergen (Fel-d1). About 50% of Siberians were found to have lower Fel d1 levels than normal cats. Under 15% of Siberians produced very low levels of the allergen, and could safely be placed in homes with severe or dangerous reactions to cats.
