2 things:

first, rabbits should run faster than you sprint.

second, this is on the creation of warrens/bolt holes:

Bunnies should be able to dig through 2 dirt blocks (it would in actuality be 3, but start and end in centers, causing 2) these would be created by bunnies digging under 1-block thick walls to access food. The bolt-holes would consist of 2 entry/exit blocks which would point toward each other, and 1 tunnel block which connects them. the bunny would make dirt particles and be slowed to 1/2-1/3 speed while going through the hole. It could also be flooded forcing the bunny out of the opposite end. They wouldn't be usable during rain. On creating warrens, there would be a rare chance that it is created when there are 2 adult (parent) rabbits near the grass block, and no player is around.
