Siberian cats are designed by nature to survive. They are generally healthy, hardy, strong cats that can take up to five years to mature, with females generally being smaller than the males. The general impression of the body is one of circles and roundness, rather than rectangles and triangles. Although it has not been proven scientifically, it has been found that the Siberian is generally a hypoallergenic cat type. In fact, many allergy sufferers who have a sensitivity to the FelD1 protein, live completely reaction free lives with their Siberians as pets in their homes. This is due to the fact that these cats have a lower than average occurrence of FelD1 protein which is usually found in the saliva of most cats, and is also secreted through the skin, anal glands and urinary system. When a cat licks its fur, the saliva dries and flakes to create the dander to which people are allergic. This can vary from cat to cat and person to person. If you are allergic to cats and want to test your allergic response to Siberians, it is best to test with the Siberian you are thinking of getting. Spend time with it to d find out how you react. There are no guarantees, but there is hope for allergy sufferers. Siberian cats are very personable and want to be near their owners. They enjoy the company of children, dogs, and other animals. They are fearless and easy going. Not much disturbs their natural calm and equanimity. They seem to know when they are needed for psychological and moral support, and spend time with the person who needs that support. They are a quiet breed that expresses itself in a melodic way through sweet mews, trills, chirps, and lots of purring. All types of toys intrigue them. Some learn to play fetch, while others are intrigued by the moving cursor on the computer screen or sit and watch, entranced, as you type. Acrobatic by nature, the Siberian cat will play hard, often executing amazing somersaults in pursuit of a feather toy. An over enthusiastic kitten may need to be rescued while attempting to climb the bricks on the fireplace or jump to the top of a bookshelf. Siberians stay playful throughout their lives. In selecting a Siberian kitten, consider which characteristics are most important to you and discuss them with the breeder, who knows each kitten and can help match you with the right one. Kittens are usually available between 12 and 16 weeks of age, by which time they have had their basic inoculations and developed the physical and social stability needed for a new environment. Keeping such a rare treasure indoors, neutering or spaying, and providing acceptable surfaces for the natural behaviour of scratching are essential to maintaining a healthy, long, and joyful life.
