i say high yellow because she doesn't have as many spots as a normal and looks a little brighter in the pics too. i looked in the leopard gecko manual (the one by phillipe de vosjoli) and there was a pic of a high yellow that looked similar to her. of course there is a lot of variation in high yellows, probably all the way up to ones that don't have many spots at all. i could be wrong though--like i said--i'm not that great with the leo morphs.

if you do decide to get her a cagemate make sure to get one that is the same size as she is and female. i don't know that she would necessarily benefit from a cagemate--leos don't require companionship so that is mostly up to you. i can't really say how she would react--i don't know if they become solitary once they live alone for a long time.
