Different rabbit breeds have different life expectancies,
and of course, any number is just an average. Rabbits
should be expected to live at least 5 years; they can
live as long as 15 years. Medium and large sized rabbits
tend to live longer than dwarf rabbits.
Breeding rabbits can easily produce litters until they
are three to four years old. Some does will have litters
even when they are older.
