End to life worthy of being envied.

I love that Magawa's wikipedia article is structured just like a human: Early Life, Career, Retirement and Death.

A few weeks ago when "Croatia declared free of landmines after 31 years" was posted here (https://news.ycombinator.com/item?id=47189535), I rabbit holed wikipedia about landmine-sniffing animals. It's such a fascinating topic.

How does one rat mentor another?

  • You can teach a kid to change a tire without saying a word. It’s the same thing. Rats are very smart and very social. Rats that were good at teaching Rathood to their little ones had more that survived.

    Put food in a maze and I’m sure rats would teach other rats how to get it. I expect this is similar.

    • Our dog learned to find tennis balls by smell off a dog that was good at it. This was after me one walk with this dog.

      Every trip to the park got us a few.

      Then he ate one and have himself a bowel obstruction and me a great enthusiasm for pet insurance.

  • Rats are intelligent social mammals. They teach by actions. Imagine training a dog. You have two dogs, one trained and one not. You say "sit" and the trained dog sits and you give it a treat. The non-trained dog will quickly pick up on that.
