Without being placed in cold storage, the pet's body will begin to decompose (this presents a health risk!) One stage of this process is known as rigor mortis. This is when the energy supply to the pet's muscles deplete.
The smell will be strongest near the carcass, but it can also spread throughout the entire home. Not only is the smell unpleasant, but it can also cause respiratory problems and nausea. If the rat has been dead for a while, the odor may become so strong that it's impossible to stay in the house.
