A Siberian Kitten typically lives 12–15 years. Most of what determines whether it gets there is routine care rather than anything dramatic.
Vaccination
Core feline vaccines plus rabies from around eight weeks, then boosters. Indoor-only cats still need them.
What “affectionate” means day to day
The Siberian Kitten is described as affectionate, playful, strong. Of those, affectionate is the one that shapes an ordinary day most. It is easy to read as a selling point and harder to live with than the word suggests, because it does not switch off when you are busy.
Planning for about 13 years
A Siberian Kitten is with you for about 13 years. Budget and routine both need to survive that, including the last quarter of it when a small cat needs more veterinary attention than it did young.
The annual check
Once a year for an adult cat, and book it before the hot months rather than during them.
Low-shedding, and what it costs
The Siberian Kitten sheds little. That is why the coat needs more work rather than less: hair that does not fall out mats against the skin instead, so clipping becomes a scheduled expense.
Keep the records
Booster schedules run from the original dates, and a new vet asks for the history first.
Balancing affectionate against playful
Breeds described as both affectionate and playful need the two managed together rather than separately. With a small cat that usually means a predictable routine first and training second - the routine is what makes the training stick.
