FYI- ALL CATS ARE COLD BLOODED KILLING MACHINES!!!
Walking the dog today I saw noticed a cat about 20ft away, it was resting next to the curb under the shade of a tree looking cute as can be.
A bird quickly enters the scene and goes for a landing on the street without seeing the cat. As the bird is getting ready to land the cat leaps 2ft in the air, knocks the bird down with its paws then snaps it's neck all in about 1 second before casually walking off with the dead bird in its mouth.
