It may be a strange title but most of the time, I forget these three are members of the order of Rodentia, the single largest group of mammals. They are characterized by a single pair of continuously growing incisors in both the upper & lower jaws.
That being said, when you think of rodents, you don't think cute or even adorable. But hopefully that opinion will change seeing the following group of photos.
