My Djungarian hamster is in love with these things. They're great to keep his teeth filed down, and at the same time make him work for his food. I do advise not letting your dwarfs have it for too long at a time, as the sugar content in honey can cause some health problems in the diabetic prone, which is why I only give it to him in short incraments. When he eats out the treat part, I recycle these and restuff them, giving them to my rabbits. All in all it's a great investment and you can reuse the logs.
