Just passing through while Googling for safe ways of killing rats without risk to other wildlife.
One solution for those who are kinder to rats than I am was published widely in June/July 2019 about an engineer (Ben Hamm) who used AI (Artificial Intelligence) to create a cat flap that would discriminate between his cat carrying prey and same cat without prey and lock the flap if it was carrying prey.
You can find BBC links and many others if you Google:
Cat Ben Hamm
This may sound like science fiction but it isn’t that far-fetched any more. A Raspberry PI with night vision camera is available for around £60 and the image recognition ‘training’ to discriminate between hog, rat, mouse, weasel, cat and fox is simpler than Ben Hamm had to tackle.
Hopefully on Dragon’s Den in the near future….
