Hi, Amybondgirl! *grin*Am I right in thinking you're a Doctor Who fan? I am too.
Anyway, I might be able to help with your pleo. IMR and Crewella are both right but I have another possible reason for her being so down in the dumps. It could be her real time clock and when you're playing with her. If her clock is set to actual noon, and you are playing late in the evening- let's say after six when the sun is down- that could be part of your issue. Despite how happy Ryu might be in the morning when I feed her, if I play with her again later in the day like after six or seven in the evening, she cries and whines and scratches her chin and doesn't want to have anything to do with me. If you can, try playing with her closer to the time her real time clock is set for, and as always, make sure she's well fed and in a very brightly lit area. I'm not sure if my advice will make any difference, but there ya go.
