It's just walking in circles and not stopping? I'm sorry, I need more information. At this point I could tell you it had rabies, but it wouldn't be right ,unless you told me other symptoms its having. Leave me a msg in my shoutbox on my profile and ill try to help!
maybe OCD?
It is far too hard to diagnose .. It could be anything from following an insect on the floor to neurological issues .. If it continues to an abnormal behavior them you should take it to be examined by a vet
Thats easy, properly he/she want to get out of the room:), my cat is doing the same
