Circling around

Recently I realised that xiao bai (my white ragdoll cat) starts to circle around the living hall while I'm watching TV. So i decided to ask my good friend "Google" what's wrong with cat circling around the house. Is there anything wrong with him? While I search, i've got some results:

1) He might be having ear infection that causes this action
2) It might be some neurological disorders happening in his body
3) He might be just bored

I started to recall back how was he behaving for the past few days. He has been eating well, sleeps alot, meow at me as usual, purring when i cuddle him... And he also gained weight. So, I pray that it is not the 2nd cause. Will be checking on his ears when i get back later today, and also, if ears are cleared, I will give him more attention then. :)
