Kids, my chubby little one went crazy about this snack. Every time he wakes up, he goes and nibbles and rocks his teeth. He loves it. It contains a plastic hook that you can put between the bars on the ceiling of the cage or the aquarium if there is somewhere to hook it, which is very practical to be vertical. It can also be placed inside a tunnel with holes to increase the difficulty and make it more interesting for the hamster during mealtime. It contains 2 large pieces and keep in mind that it does not need frequent purchase as it seems to last for months. I will buy it again.
