That is what I am worried she might develop. I can hope that since the transit was only 24 hrs and started in Miami that her chilly adventure and the settling of the heat pack away from her in the container was significantly less. Still she was so lethargic when she arrived her strike attempts was pitiful - then as she warmed up her eyes were jerking periodically (like a twitch every 15 seconds or so). That quickly abated, which is good because it was really freaking me out. I'll be watching for that elevated head maneuver.
