Hi, I'm Brock and I'm new to owning rats and to this site. I was wondering if you could help me. I was setting up the tree and we have these jingle bells on a type of rope to put on the tree and when I was putting it on it was making the noise a jingle bell makes. Soon after my baby girl by the name of Diamond starting running around super fast and running into the sides of cage. After she finished she went under her tube and didn't move for a good 3 minutes. If you know what happened please tell me because i have no clue what it could be.
