Sadly, both kittens you are abut to see have just died due to breathing failure. They died a few months after they were born, at the end of October 2010. RIP, Charlie and Spike.
The two kittens had a rare decease called myotonia congenita, also known as ‘fainting goat’ syndrome, more common for goats. The decease had never been found in cats before. At the slightest sound or movement, the kittens responded by collapsing into a rigid paralysis which typically lasted for one minute until they returned to normal.
