California DHS Report on the alleged dangers of ferrets as pets.
In 1988 the California Department of Health Services published an anti ferret report titled “PET EUROPEAN FERRETS: A HAZARD TO PUBLIC HEALTH, SMALL LIVESTOCK AND WILDLIFE”.
The report is authored by Denny G Constantine, an expert in bats with no ferret experience.
The report was widely panned for its unscientific approach and use of anecdotal material.
