We had a cat once that started walking in circles, had to have him put down. The vet thought it was caused by brain damage, possibly a clot broke free from an old injury (he was a street cat, we were one of his regular caretaker stops, along with the mailman & a couple other places)
That's what I was thinking. We had a hamster at PetCo who would just sit there and run in circles ALL DAY. Turned out he had brain damage. Luckily for him though a coworked adopted him.

I would take him to the vet to get him checked out. You can never be too cautious!!
