At first glance, this is a funny gif/video. However, the truth about these two cute kitties is that they suffered from a debilitating condition known as myotonia congenita, or fainting goat syndrome. Their names were Charlie and Spike and they died in October 2010. The condition prevented them from running and jumping, so it's not as if the only symptom was fainting. Anyhow, I figured you'd be interested to know this. Perhaps you already knew?
