       | I did not expect this to be as thoughtful as it is. Kudos to the
       | thought put into the setup and training. Building custom hardware
       | for the rat is amazing.. I need something like this for my own
       | setup.

       | rats killing Daemons though, only a promising but broken link.

       | Sorry guys, no video of them playing on this setup, just on the
       | previous version. We iterated on v2 too long, our pet rats grew
       | old and couldn't be trained. We open-sourced the hardware and
       | software so others can build upon it. Here's a cute video though
       | of Todd being habituated to the setup:

         | gaming rigs for rats need to be developed - it looked like Todd
         | was actually enjoying it, and you toned down the potentially
         | scary bits in a good way.
         | 
         | Kudos for the experiment and giving your pet an awesome
         | enriching environment!

       | hehe very important

       | although... if the walls moved and touched the whiskers in

         | yeah good point! we actually have air puffs for that. we
