What the numbers say

- Shedding: Russian Blue is lower than Persian.
- Energy: Russian Blue is higher than Persian.
Size, longevity and the practical difference
Persian weighs 3.2–5.4 kg (7–12 lb) and stands out at Body 40–50 cm (16–20 in), tail 25–30 cm; Russian Blue weighs 3.0–5.0 kg (6.5–11 lb), Body 38–46 cm (15–18 in), tail 28–33 cm. Lifespan is 12–17 years against 15–20 years. In practice the heavier cat costs more at every vet visit (drugs and anaesthesia are dosed by weight), needs sturdier cat trees, and carries a higher baseline risk of joint load. The lighter cat is easier to keep slim and cheaper to medicate, but has less margin if it loses weight during illness.
Time you actually spend per week
Coat and skin work is the recurring cost. Persian sits at grooming difficulty 5/5 and heavy shedding, which is roughly <strong>110 to 176 minutes of combing a week</strong>, more in spring and autumn. Russian Blue sits at 2/5 and light shedding: about <strong>25 to 40 minutes a week</strong>. Play is the second cost: Persian has low drive, short daily play is enough; Russian Blue has moderate drive, two proper sessions a day. Budget 10 to 15 minutes twice a day for either, and a food puzzle for the lower-energy one so it does not simply sleep through the day.
Health screening before and after you buy
Persian's headline risk is Polycystic kidney disease (PKD). Russian Blue's is Progressive retinal atrophy. Ask for the parents' DNA test results and the most recent cardiac ultrasound report; both breeds' calendars on this site list which tests are worth paying for and how often. Weight is the lever you control: a cat one kilogram over its ideal weight has measurably more arthritis and diabetes risk, so weigh monthly and act at 10% above target.
Which one fits your household
Energy 2/5 and vocalness 2/5 for Persian against 3/5 and 2/5 for Russian Blue; affection 4/5 against 4/5. Both lean towards people. If nobody is home for ten hours a day, neither is a good fit on its own unless you take two cats or arrange a midday visit. A first-time owner or a home with young children should pick the calmer, more tolerant of the two; an experienced owner who wants interaction should pick the busier one.
