I have had my Guinea Pig Lacey now for a week and already she has adapted very well, she loves cuddles and running around my living room (when I'm home) and gives lots of kisses etc, however I put her back in her cage last night before going to bed, she seemed ok and was eating her hay then all of a sudden I heard a bang like she had bounced off her cage, I went to investigate and she was hnaging from the bars at the side, she normally runs if I put my hand inside the cage but she looked so scared like she didnt want to be closed in. I'm worried that she will panic too much if left inside her cage while I'm out... and suggestions? :{
