Like all hamsters, they are rodents, which means they have constantly growing incisors (front teeth). These teeth need to be worn down, and they do this by gnawing.
Their teeth are quite sharp and strong, and they can be used for a variety of tasks, including:
* Chewing food
* Grooming
* Digging
* Defending themselves
It's important to provide your dwarf hamster with plenty of chew toys to help keep their teeth trimmed and prevent them from becoming overgrown.
