In areas where no natural predators exist, rabbits can cause considerable economic loss by depleting the vegetation. Handling To lift a rabbit, one should grasp a large fold of loose skin over the shoulders with one hand and either support of grasp the rear feet with the other hand.

Frightened or so-called nervous rabbits are usually easily carried by this method.
