What gives dead cats that distinct smell?

What gives dead cats that distinct smell, is it a certain thing in cats that lets off that smell as they decompose, or a mix of everything?

Is there any way to harness and store that smell, perhaps in a liquid or powder form?

What would be the best way to totally hide that smell while the powder or liquid is in storage?

asked in the social section as i did not think the smell of dead cats would be a proper thing to ask in the general section, even though i am seeking a real answer
