In the aftermath of the nuclear blast, footage of a cat supposedly "suffocating" outside in the extreme heat is shown. This is actually footage of a cat enjoying a hefty dose of catnip, then they just reversed the film to give the impression of the cat suffocating (the way the cat is rolling on the ground is the giveaway).

If anyone dies while you are kept in your fallout room, move the body to another room in the house. Label the body with name and address, and cover it as tightly as possible in polythene, paper, sheets or blankets. If, however, you've had a body in the house for more than five days *and* if it is safe to go outside, then you should bury the body for the time being in a trench or cover it with earth, and mark the spot of the burial.
