I may be premature on this review. Anyone who owns an African Grey will tell you there's no puzzle.they cannot solve.
I got so tired of him throwing his screw-down dishes on the floor wasting food. The description of these dishes made it sound like.they were.for much smaller birds. But I was desperate. Although shallower, the surface area is about the same as my screw-in 10 oz. Although a little more flimsy than the 10 ounce, so far they have survived his.destructive beak. He did.figure out how to push the tab back and pull the one straight out and.throw it to the floor. I think it was his "I'll show you!" Moment. But since, so far, he has not done so although there is no doubt he could. Go figure! But since it has only happened once so far, I thankfully give it 5 stars.
