Struggling frequently leads to fracture of lumbar vertebrae and injury to the spinal cord that may necessitate euthanasia. Rabbits may exhibit sudden violent efforts to escape during restraint. In the process, intravenous needles, gavage tubes, etc. can be dislodged causing spills or otherwise endangering themselves or personnel. Therefore, complete restraint should be accomplished before attempting such procedures and rabbits should never be left unattended in restraint devices. Investigators requiring the establishment of breeding colonies should consult with the Animal Care Unit to assure proper management of the colonies.
Restraint Devices Several types of devices are commercially available to restrain rabbits.
Quality devices prevent the animal from turning around or twisting yet allow easy access to the head and ears. Care should be taken when placing a rabbit in a restraint device since struggling may result in damage to the spine. Sexing Rabbits can be sexed by causing eversion of the penis or vulva when slight pressure is applied to the external genitalia. 23 Transport Rabbits should always be transported in a transport cage. Investigators unable to locate an available transport cage should ask the facility supervisor for assistance.
