The tops of the feet should be covered with hair. Courser type hair than the rest of the body. The tips of the toes will have more pointy fur thats longer. (don't cut that!) They do NOT need their nails trimmed they normally do fine on their own. However, some people choose to, i do not, seeing its NOT needed.

The bottoms of the feet should be much like a cats paw pads. (they will be much more dry, like they need some lotion.) You can put nonscented baby lotion on them, but only do this if their feet are terribly dry & cracked; olive oil also works well!
