Cervical dislocation
Cervical dislocation is a common method of animal euthanasia. It refers to a technique used in physical euthanasia of small animals by applying pressure to the neck and dislocating the spinal column from the skull or brain.[1] The aim is to quickly separate the spinal cord from the brain[2] so as to provide the animal with a fast and painless death;[1] however, research on this method has shown it does not consistently concuss the brain and may not cause instantaneous insensibility.[3]
Technique
Apply firm pressure at the base of the skull, sharply pinching and twisting between thumb and forefinger. At the same time, pull backward on the tail.[4] This severs the spinal cord at the base of the brain or within the cervical spine area (the upper third of the neck).[2] According to the Canadian Council on Animal Care (CCAC), cervical dislocation is normally only conducted on small animals.[1]
Ethics
The University of Iowa and some veterinary associations consider the technique as an ethically accepted method for terminating the life of small rodents such as rats, mice, squirrels, etc.[5]
