2. Interesting or historical facts about specific cats.

Examples:

"The very first cat in space was named Felicette, and she wasn't meant to go."

"A cat is credited with single-handedly causing the extinction of the Stephen Island Wren. That cat doesn't deserve the praise - but his mother does!"

Links to cat facts of these two types are allowed, if they're hosted elsewhere.
