Pet owners will do anything they can for their companions, including buying every kind of toy that promises to improve their lives. But instead of stimulating a dog's brain, this chew toy looks like it's only going to stimulate frustration and rage.

You can actually put anything inside this £10 Cagey Cube rubber prison—tennis balls, snacks—as long as it's large enough to not fall through the cracks. Because it's supposed to be up to your dog to figure out how to free it. Except that dogs don't have opposable thumbs, or even dextrous hands covered in fingers. All they have is teeth, and after a few frustrating hours when they discover that's not enough to free their favorite toy, they just might turn on you for imprisoning it in the first place.

Will This Caged Ball Toy Stimulate a Dog's Brain or Just Drive It Insane?
