Had a dead mouse once. It can get bad. But it passes after a few days. Not saying that it's not. But it's a different smell then body waste.
Last spring i had a dead mouse odouring from somewhere in my bedroom. I taped off some holes in the wall, behind the light switch. I tried to look everywhere, but no mouse.
Untill i couldnt sleep anymore from the mouse stink irritating my throat. Then i turned the whole bedroom upside down. When i lifted a two seat couch off the floor to inspect thoroughly, did a step back to watch over the couch in my arms to the floor where it sat, i felt something under my foot....
I put the couch back, KNOWING on what i just stepped...
I found the mouse lying close to a leg of the table besides my bed, halfway hidden under the table cloth that hangs allmost to the floor...
I removed the mouse, and sprayed half a bottle of ADIDAS sports deodorant on the spot where the mouse has been rotting for a week or more...
Everytime i smell this ADIDAS deodorant, i my eyeballs pop into surveillance mode, thinking where the dead mouse might be...
Because both odours were overwhelmingly present at the same time, in my subconsciousness, this smell is connected to the smell of dead mice. I had no other option than to throw away this deodorant, because the smell just remembers me of dead mice anytime during the day...
