Adorable Fainting Kittens Are Adorable (Updated)

In this video, kittens Charlie and Spike both become momentarily paralyzed as they play due to myotonia congenita or “fainting goat” syndrome. The condition is extremely unusual in cats and prevents them from running or jumping, but otherwise they’re normal.

Update: We were unaware that the black kitten had passed away from complications due to this condition. This makes things considerably less adorable.
