I bought this a while back and have been using it both for fun when the weather isn't so great and for those of our fosters who eat way too fast. Easy to use. Just put kibble or treats in the compartments and let your dog (or cat) figure how to get them out. First timers sometimes need guidance from their humans.
The quality is very good, a hard plastic with a non-slip bottom that's very easy to wash. The dogs seem to enjoy it as well.
I have only one concern and I only noticed it tonight...Katie's first time using it. Maybe it's because her snout is short and stubby but, she was using her tongue to lift the kibble up along the sides of the compartments. In the section of the A´kiou where the spinner is located, I was afraid her tongue would get stuck between the top of the spinner and it's compartments because the top turned slightly as she raised the kibble out. I looked carefully and the top of the spinner can be lifted about 1/2 a centimeter. The four other sliding-top compartments give me no concerns as the tops don't move while the kibble is being foraged for.
All in all, I give the A´kiou
out of 5 only because I worry about a little tongue getting stuck
. I'll certainly still use it but only under supervision.
Personally, I think it should be marketed for use in cats too. I think they would have much fun with it as well.
