How long do rabbits live?

Well-cared-for pet rabbits usually live 8 to 12 years, with smaller breeds often living longer than giant breeds. The calculator uses a typical lifespan of 10 years and scales it to a human lifespan of 80 years, so one rabbit year counts as about 8 human years.

Rabbit life stages

Rabbits reach sexual maturity at just a few months old and are fully grown at around one year. From about 6 to 8 years old most rabbits are considered seniors and may need softer bedding, closer monitoring of their teeth and weight, and more frequent vet visits.

Keeping your rabbit healthy for longer

A diet based mostly on hay, plenty of space to hop and run, a companion rabbit, neutering and vaccinations all contribute to a long and healthy life.
