No. Hares and other rabbits are not ruminant animals. They are pseudo-ruminants like horses and zebras are, which means all fermentation occurs behind the stomach, not in front like with cows, sheep and goats. Fermentation occurs in the cecum for pseudo-ruminants, whereas with cows and sheep, fermentation occurs in primarily the rumen as well as the cecum.
