Riker and Lei are closely fond of each other since I brought them here since March. All grown up mostly with Riker and his excess fat or fur. I got a chance to see them roam inside my room for one night, while re-watching the season 4 of Star Trek Enterprise.
Lei is the one who always wants my attention running around and jumping in front of my portable DVD player. Riker on the other hand just watch the video with me or being chased around by Lei. These guys know how to rumble when I wanted them to just lie down on the floor. Now I know why Lei needs attention, because he just needs a bigger space to play more with Riker.
