Pioneering Study Suggests Cats May Be An Overlooked Forensic Resource » TwistedSifter


When you think about investigating crime scenes and what evidence needs to be carefully cataloged and collected, people’s pets are probably not the first thing that comes to mind.

This study, the first of its kind, suggests that the potential contribution of nearby cats should not be overlooked.

Flounders University researchers have posed the question whether or not human DNA can be extracted from a cat’s fur – and if so, could it help place potential criminals at a crime scene? when other methods fail.

The preliminary answer, at least, seems to be yes – 80% of the cats sampled contained the DNA of the people they lived with, and the samples largely had enough integrity to be matched with the source.

The idea was born out of Heidi Monkman’s doctoral research.

“I love animals. When I pitched the idea to (co-author) Dr Mariya Goray, we found there was very little research in the field, so we were eager to get started.

Now that they have established the fact that cats keep pieces of the humans they have contacted in their fur, the scientists want to carry out further tests in the future.

First, they would like to know if other pets, such as dogs, do the same. They’d also like to test how long a person has to stay in the house before their DNA can cling to cat fur – could a burglar’s cells show up, for example, and not just the people there. live.

Monkman says future experiments should also attempt to control different feline personalities.

“They [the cats] were selected for their friendliness and not to be stressed by new people.”

The more cats, the more personalities, and the more difficult the testing procedures will be.

Researchers also believe they can find out whether or not the contents of a cat’s fur are likely to contaminate a living environment.

“Are these DNA findings the result of criminal activity or could they have been transferred and dropped off at the scene via a pet? DNA passed down from someone who patted it outside so it looks like the individual was in the house at the time of a crime seems like the kind of thing some cats would like to do.

Be careful when insulting a cat. It seems they have many ways to exact their revenge.
