CleverPet is pretty awesome and HackerPet makes it awesome-r.
We make custom games for our food-motivated black cat and he spends time every day playing the games for kibble, rather than meowing and knocking pictures off the wall. You'd get that with the base CleverPet, but I'm especially interested to try out some of internet-connected and phone-connected games we're seeing coming out for HackerPet. It's the wild west of understanding animal behavior, and this is a cool opportunity to be a part of learning what animals are capable of, while bonding with your own pet.
