Viral footage from China shows the farm animals continuously circling the same spot for no apparent reason.
According to the owner of the sheep – Ms Miao – only a small handful of the animals had exhibited this unusual behavior to begin with, but it wasn’t long until the rest of the flock had decided to join in.
While the farm animals’ constant circular pacing seemed nothing particularly unusual initially, Miao was left scratching her head when they continued to do it non-stop for 12 days straight.
Even stranger was the fact that, on a farm with 24 sheep pens, the sheep in this particular pen (number 13) were the only ones to start doing this.
As it happens, however, the explanation for this phenomenon is likely to be rather mundane.
Listeriosis – a disease typically associated with spoiled sheep food – is known to cause inflammation on one side of the brain, resulting in disorientation and a tendency to walk around in circles.
In all likelihood, this is what is afflicting the sheep in this particular case.
