Russian Blue vs Siberian
A medium, quiet, reserved short-coat for a small flat against a large, playful, thick-coated family cat that wants room.
Verdict
Size, coat and sociability separate these two. The Russian Blue is medium, short-coated and quiet, shy with strangers, and it fits a small flat. The Siberian is large, athletic and playful, with a dense triple coat that needs regular combing, and it is reliable with children and other pets. Choose the Russian Blue for a calm household with a regular routine and little grooming. Choose the Siberian for an active family with space for a big, sturdy, sociable cat and a comb in hand.
Choose the Russian Blue if
- You live in a small flat; it scores 5 for apartments against 3.
- You want light grooming; it scores 2 against 4.
- You are out for a workday; it scores 4 for independence against 3.
- You want the cleverer cat, scoring 5 for intelligence against 4.
Choose the Siberian if
- You have children and other pets; it scores 5 for both against 3.
- You want a more energetic, playful cat, scoring 4 for both.
- You want a large cat of 8-18 lb.
- You will comb a dense, water-resistant coat that thickens in cold months.
Where they are alike
Both are intelligent cats that score 4 or 5, and both are affectionate with their own household. Each lists no more than a short set of concerns, and your vet can explain them.
