Answer
Marsha,

Put your cactus under a desk lamp with a florescent daylight bulb in it Keep the bulb about 6-8 inches from the plant so it gets lots of light. Have the light on a timer set up so the plant gets 14 hours of light per day, that will keep it healthy all winter.  Be very careful not to overwater it and never leave it sit in a drain tray full of water or you will rot the roots. Good luck!
