How the British Shorthair ages
The British Shorthair weighs about 7–17 lb and typically lives 12–20 years. Like all cats, it ages fast early: about 15 human years by age one and 24 by age two, then roughly four human years for every calendar year after that. A 5-year-old is around 36 in human years, and a 12-year-old about 64. This feline curve reflects how cats really age, unlike the flat "multiply by seven" rule that overstates a kitten's age and understates a senior cat's.
