My family has had many rodents as pets and tips I would give to another rodent owner would be as follows:
1. They breed VERY fast.
2. Most rodents spend a lot of their time trying to escape from their cages.
3. They can fit in very small cracks.
4. They have sharp teeth.
5. Don't ever try to pick one up while it is sleeping.
6. Give them occasional treats of fresh vegtables. (Not too often)
7. If they gnash their teeth at you they are mad at you.
8. They are unbearably cute and fuzzy.
