- Dental Care. It’s very important to clean your pets teeth and perform other kinds of dental care. The older your pet is the higher the chance it may need the teeth extraction. If you buy a special toothbrush that you can put on your finger, you’ll be able to take care of your pet’s teeth while at home. Rodent owners should watch out for their pet’s teeth getting too long. To prevent that there need to be some things in the cage that your rodent can chew.
