We have one. My daughter named it Mr. Creampuff years ago. Really easy keepers.
Ours was young, but nearly full size when we got him. If you've never had one, a larger one will give you a great margin of error while you are learning. On the other hand, as long as you put out the food daily, keeps things clean, spray the enclosure twice a day, and keep the temperature in the 70s, you should have no problem with a baby either.
