So I was wondering .. there are soo many things in the market to stimulate a person's brain, you got to give your brain a work out and same has to apply for pets and THERE IS!!!
I received Kyjen's treat triad as part of a product review and although marketed for dogs, turned out to be the greatest puzzle solved in this household.
It's a colorful standalone triad with 3 compartments. The top (red) is a spinner that needs to be turned to unlock the three compartment where treats are stored. There are holes on top of the spinner and compartment doors so that they can smell the treat.
This is the second time I introduced the triad to them. Pardon the background music it caught me by surprise. Now, about two weeks in... They are both experts, Maya lifts the doors and keeps her head inside the compartment so that the it wont close. and she now opens it with her paw as opposed to her head.! haha! too cute.
Very Important: It's super easy to clean, if needed, just wipe down with a damp cloth (or papertowel) and done.
