In Holland’s embassy in Moscow, Russia, the staff noticed that the two Siamese cats kept meowing and clawing at the walls of the building. Their owners finally investigated, thinking they would find mice. Instead, they discovered microphones hidden by Russian spies. The cats heard the microphones when they turned on.
Thanks for the comment @catfacts. Would you upvote this?
If your cat snores, or rolls over on his back to expose his belly, it means he trusts you.
Cats respond better to women than to men, probably due to the fact that women's voices have a higher pitch.
