The accuracy of a veterinarian's diagnosis and therefore the success of the therapy regimen based on that diagnosis depend upon adequate restraint of the patient in order that a revealing physical examination can be performed and necessary treatment can be accomplished. This is no less true in the case of exotic or wild animal pets than it is in the case of domestic species with which veterinarians are more familiar. It is axiomatic that the least restraint be used that is still commensurate with the aims of the procedure.
