Kaytee Knot Nibbler Mini Colorful Wooden Chew Toy for Small Animals

We got two gerbils for our daughter. A few little shaped wood chewers came with the habitat that we bought for them, and they chewed on them but they went fast and got buried under the bedding easily. We also had a problem with them chewing on their habitat tubes as well as their food dish that was plastic and eventually was completely chewed down to nothing. So we got this super pet nibbler and it is great. They climb on it and chew all over it and it does not get buried under the bedding. The chewing on the cage has pretty much stopped. So this was perfect. It has not broken down into pieces so it is holding up quite well to two gerbils eating on it.
