This tutorial is pretty self-explanatory, so I won’t bother typing a bunch of words unless someone gets stuck – if you do get stuck, just let me know! One thing I will say is that after you’ve added the treats, don’t be shy about adding more cardboard strips – really jam them on! The more you can add, the harder it will be for your rats to get it open.
My ratties love tearing these treat puzzles apart. I like to throw one or two in when I leave for work. Even though the puzzles will be destroyed in just a few minutes, it’s something to keep them busy and mentally stimulated.
Enjoy!
