Birman vs Siberian

Both are sociable longhairs for families; the Siberian is larger, livelier and sheds more, while the Birman is smaller and calmer.

Verdict

Both score 5 for children and other pets, rate 2 for voice, and fit a family home. The one thing that decides it is size and pace. The Siberian is a large, sturdy cat of typically 8 to 18 lb, with a thick triple coat, energy at 4 and heavy shedding. The Birman is a medium cat with a silky coat and little undercoat, energy at 3 and moderate shedding. Choose the Birman for a smaller, calmer companion and the Siberian for a bigger, playful one.

Choose the Birman if

  • You want a medium cat rather than a large one.
  • You prefer a calmer cat, with play at 3 against 4.
  • You want a silky coat with moderate shedding and combing a couple of times a week.
  • You live in a smaller home, since apartment living scores 4 against 3.

Choose the Siberian if

  • You want a big, sturdy, active cat that enjoys play.
  • You will comb a thick coat and accept heavy shedding.
  • You can give it room to climb.
  • You want a cat that copes better alone, with independence at 3 against 2.

Where they are alike

Both cats are friendly, quiet and affectionate, with affection at 4. Each lists a kidney item for the vet to watch, so ask your vet and the breeder about testing.

Allergies No breed is hypoallergenic. The silky coat has little undercoat and sheds in moderation, but people who react to cats may still react to a Birman. No breed is hypoallergenic. Some owners report fewer symptoms with Siberians, but there is no good evidence for it and individual cats vary.
Suits A household that wants a sweet, calm, people-loving cat and will comb its coat a couple of times a week. A family or a household with other pets that wants a sturdy, playful, sociable cat and will comb a thick coat.
Less suited to Anyone who is away most of the day, or who wants a very active and independent cat. A small flat with little room to climb, or anyone who cannot spend time grooming and playing.
