Here is just a simple way to help your hamsters teeth from getting over grown. Their teeth are naturally yellow, and the bottom teeth are suppose to be longer then the top teeth. Though if you don’t watch your hamster and it’s teeth and your hamster is not chewing, their teeth can become overgrown. So if this happens it is nice to know you don’t have to go to the vet to have your hamsters teeth clipped. Just keep in mind most hamsters will trim there own teeth, it is uncommon for them to not naturally do so on their own. Mine normally keep their teeth the right length, I mainly did this video to show you what you could do if you are seriously worried about your hamsters teeth.
