What is the average life span for a bunny?

Answer 1

The average live expectancy is between 8 and 12 years.
The lifespan depends on the breed. Some, 20 years.
The average lifespan of a rabbit could range form 6-12 years (about the lifespan of a large dog).

Answer 2

The Life Span can depend on how you care the rabbit, so for example if you keep your pet rabbit inside and safe from predators and feed and care it very well it can life up to 6-10 years, but sometimes longer.

Also inside or outside the life expectancy is the same (in how you care it for).

Here are a few other info:

Smaller Rabbits have been known to live to 13-14 years when kept as a house rabbits and well cared for. The average lifespan is about 8-9 years however.

Larger breeds can live to about 8-9 year in optimal conditions, although their larger size can make them very prone to health problems, especially heart conditions.
