Buster Food Cube’s idea is great because a cube won’t roll by itself on the floor but needs to be pushed all the time.
This is also a great toy for dogs that are mouthy because of its shape and size - it just is too difficult to bite. You can buy this toy in two sizes and this is the larger one (4,5”).
Then the downsides.. the toy is poorly designed on the inside. Majority of the kibble fell out in the beginning and the last remaining kibble were extremely hard to get out. Also, the toy doesn’t properly open for cleaning.
The toy is made of hard plastic and it makes a lot of noise on a hardwood floor. On the carpet the noise wasn’t as bad but the sound was still quite loud because the kibble bounced inside the hollow cube.
Unfortunately this toy didn’t fill my expectations. If you are about to buy this toy I recommend that you skip it and choose something else.
