I know it's been awhile since you posted this, but I just came across it. Has this happened again since then? I'm wondering if her blood sugar was low? Silvia has done this once. She wouldn't respond to me, didn't want to play or eat, and just stayed in one spot shivering as if she was cold. I gave her a capful of Kyro syrup and within ten minutes she was back to her old self. Anyway.........for future info!
