Not perfect but well liked, needs human supervision
Had this a week. Both my (food motivated) cats have enjoyed it but both also needed human help even with the more simple challenges. On the upside it's good because they haven't mastered it too quickly and got bored. On the other hand, compared to a treat ball or food maze where you can fill it up and let them go this one (so far) needs more input from us. And yes, the slider holes are just the right size for treats/biscuits to get stuck. Glad we have it but also glad we didn't pay full price.
