I trained my rat to stand on her hind legs on top of a mini skateboard.
These are the steps I took as illustrated in the video
Each step was taught to Boy using pieces of a three gram rat pellet broken into about 20-30 pieces. If boy performed the desired movement he was given a piece of food as a reinforcement. The entire process took about 6 days using 7-10 grams per day.
1) touch the skateboard
2) mount the skateboard
3) stand atop box on hind legs
4) stand atop cap on hind legs
5) stand atop metal piece on skateboard on hind legs
6) stand atop skateboard on hind legs
I used the same technique as described in clicker training to achieve these goals.
