In 1983 the archaeologist Alain Le Brun found a cat skeleton in a grave dating to 9,500 BCE. The thing is - he wasn't in Egypt. He was on the island of Cyprus, which had no indigenous cat population. That cat was brought on purpose, and therefore predates the knowledge of domesticated cats in Egypt by quite a margin.
This and more fascinating facts are to be found in this article from the Ancient History Encyclopedia. Enjoy!
