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.

| 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. |
