Norwegian Forest Cat vs Siberian

Two large, water-resistant longhairs; the Siberian is more energetic, more sociable and more clingy, the Norwegian Forest Cat steadier and more independent.

Verdict

Both are big, thick-coated cats that climb, shed in season and need combing. The thing that decides it is energy and attachment. The Siberian scores 4 for energy, 4 for playfulness and 5 for children and other pets, so it suits a lively family. The Norwegian Forest Cat is steadier, scores 4 for independence and copes with a workday alone, but it is less playful and less of a lap cat. Choose the Siberian for a sturdy, playful, sociable cat. Choose the Norwegian Forest Cat for an easygoing one.

Choose the Norwegian Forest Cat if

  • You are away for a workday; it scores 4 for independence against 3.
  • You want less grooming; it scores 3 for grooming against 4.
  • You want a calmer pace, with energy at 3 against 4.
  • You would ask your vet about glycogen storage disease type IV, hip dysplasia and heart disease.

Choose the Siberian if

  • You want a more playful cat, scoring 4 for playfulness against 3.
  • You have children and other pets; it scores 5 for both against 4.
  • You want more affection, scoring 4 against 3.
  • You can comb a dense triple coat that thickens in cold months.

Where they are alike

Both are large, long-coated cats with shedding scores of 4 and tall-climbing needs, so neither is ideal for a small flat. Each lists hypertrophic cardiomyopathy as a concern.

Allergies No breed is hypoallergenic. The Norwegian Forest Cat sheds heavily each spring, and people who react to cats usually react to it too. 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 home with space and tall climbing that wants a friendly, steady, self-possessed cat and will comb it through the spring moult. A family or a household with other pets that wants a sturdy, playful, sociable cat and will comb a thick coat.
Less suited to A small flat with little height to climb, or anyone who wants a clinging lap cat. A small flat with little room to climb, or anyone who cannot spend time grooming and playing.
