We got this cat school clicker training kit for Christmas 2020, and began using it right away. The guide is very easy to follow, and tools are sturdy and easy to use. Our younger, more food driven cat is very eager and happy to follow the instructions. For our older cat we have to make sure she is hungry and in playful mood before clicker training. We really enjoy seeing our cats so engaged, and they are happy to get the extra attention. Great product, would recommend!
