Yes, sometimes when they are drowsy and are so relaxed that when you stroke their head their top eyelid pulls up it is possible to see what can only be explained as a white eyelid which is the third eyelid. This is perfectly normal.
However, if you are seeing this eyelid when the cat is awake then i'm not so sure this is so normal as my cats is only visible, as i've said above when drowsy. So perhaps if you are seeing this when the cat is awake, a quick trip to the vets to make certain all is ok may be advisable? But if I'm honest I'm sure it is and my initial interpretation of when you actually saw it is more accurate.
Hope this answer is helpful!

The eyelids act to protect the anterior surface of the globe from local injury.

The third eyelid which is seem in some animals and birds is called the nictitating membrane or haw as it is called, closes across the eye (unlike the upper and lower eyelids) and are there as extra protection for that all important eye. It is a transparent or translucent third eyelid present in some animals that can be drawn across the eye for protection and to moisten it while maintaining vision.
