Any harmless housecat weighing over 15 lbs (7 kg). The worst thing a heavy attack cat will ever do to a human being is take a good flying leap and land on them, thus rendering the human temporarily stunned and possibly unable to breathe.
Bob, why are you clutching your groin and crying?

My heavy attack cat thought my package was some kind of vermin.

Get the your cat fat attack mug.
When a cat stares at your soul waiting to attack at the right moment.
The cat stares for 1 hour you stand still doing nothing. 5 hours later the cat brings out his claws. 5 more hours later the cat attack jumps at your face Scratching your eye,nose and mouth. the cat scratches your hand has you try to grab the cat. The cat leaps out of your face blood dripping on your face. You try to get the bandages but it still bleeding so you wrap your face in toilet paper and go to sleep. You wake up and you die. The screen shows game over. You punched the computer screen Then you said: fuck this I'm gonna play another game
