The cat theory of Egypt!

Seems I have heard of this one before?
It seems that in the consensual past, Egypt had a city in the Eastern Delta area, that was under the protection of "cats!", or at least the cat god! It also seems that mice were also reverred in the past, and at about the same time! I know that the Assyrians were reportedly beset by mice at night which then ate all of their bow strings! Later it seems the Cats and Mice did play!
Do you remember the times and places of the above actions?
I know you are somewhat bored so I thought I'd place this question before you!
