‘Like unscrambling an egg’: scientists alter DNA to save Scottish wildcats

A bold genomic process is being harnessed to eliminate decades of interbreeding with domestic moggies

Scientists are preparing plans to restore the fortunes of Scotland’s threatened Highland wildcats – by identifying and removing DNA they have acquired from domestic cats.

Researchers have warned that the Highland tiger, as the wildcat is also known, is critically endangered because it has bred so much with domestic moggies. All animals now bear evidence of interbreeding, and many have little “wild” left in them.
