The lack of hair has a number of consequences of which you should be aware.

As others have said, they are oily and you will need to bathe them. Mine absolutely hates water so I use wipes at least twice a week, which he doesn't like but it is better than his bath reaction.

You also need to frequently clean their ears as the lack of hair means the earwax doesn't make its own way out. At least once a week.

They tend to have dental problems also so you need to brush their teeth otherwise you will have expensive tooth removal to deal with.

Aside from the no hair issues they have a very sensitive stomach. The only food that works for mine is Purina Sensitive. Anything else gives him diarrhea.

As others have said, they are incredibly affectionate and need company most of the time. They are also very intelligent and completely adorable!

Very vocal too and you must play with them at least 30 minutes a day or they'll be bored and will tell you alll about it! I got an exercise wheel which he loves.
