In 1994, 32-year-old Shirley Duguay, a resident of Prince Edward Island, Canada, was killed. Unfortunately there was no evidence linking the main suspect, Douglas Beamish, her on-again-off-again common law husband, to the crime. Then police found a plastic bag containing men’s sneakers and a jacket splattered with the victim’s blood. On that jacket were a number of white cat hairs that looked to Constable Roger Savoie suspiciously similar to the white cat Snowball owned by the suspect.

Just as human DNA is unique, so is animal DNA. By identifying the cat hair with Snowball, the police could link the crime evidence to the suspect’s cat. As a result, Snowball helped solve a crime by providing a crucial piece of evidence conclusively proving that the suspect must have been involved in the murder.

This field of veterinarian forensics is much like the show CSI but with animal DNA mixed in. If you think that your dog or cat can’t turn you in for committing a crime, think again. Your cat may be tracking your moves without you even knowing it, so make sure you don’t commit a crime or your cat could help turn you in.
