Siberian

Russia’s native longhaired cat, recognised internationally only in recent decades.

Siberians are large, sociable, remarkably agile for their size, and among the more genuinely affectionate of the big longhairs. They are also the breed most often sold on an allergy claim. That claim outruns the evidence: individual cats vary in how much of the allergen they produce, but no breed is hypoallergenic, and buying one on that basis is how cats end up rehomed.

Right for you if

You want a large, affectionate cat and will groom it properly.
You have space and height for a heavy, athletic animal.
You want a sociable cat that is still fairly self-sufficient.
You are buying it because you want this cat, not because of an allergy claim.

Wrong for you if

You or someone in the house is allergic and this is the plan.
You will not groom several times a week.
You want a small or low-shedding cat.
You want a lap cat that stays put.

The allergy claim, and the heart

No cat breed is hypoallergenic. If anyone in the house is allergic, spend time with adult cats of this breed before committing, and treat any breeder who guarantees a reaction-free cat as unreliable on everything else too.
Hypertrophic cardiomyopathy occurs in the breed and there is no Siberian DNA test — eight candidate genes were sequenced in affected Siberians and other breeds without finding a causative mutation.¹ Ask about cardiologist scanning of the parents.
The only two feline HCM mutations known are in the Maine Coon and the Ragdoll.² Any "HCM DNA clear" claim for a Siberian needs explaining.
The winter coat is a different animal from the summer one. Grooming demand is seasonal and the moult is substantial.
