Not for hamster, otherwise very decorative

The rock looks very nice and decorative! From the reviews I've learned that it is often bought for hamsters and small rodents. So I bought the rocks 25 cm for my golden hamster lady! She has also well received ... Climb and crawling happily around on them! Unfortunately, she crawled after a few weeks into the cavity of the tree trunk and hung out at the climb with a little feet firmly and was unable to extricate themselves! Has lasted quite a while until I could save them carefully (and by 7 clock in the morning)! My conclusion: Decorative but suitable for hamsters NOT !!!!
