I asked a while ago if people thought a mouse (as we thought we had) could get into an oven's surround. Opinion was divided.
Then we found we had a rat, not mice!
Rat was murdered by council RatBloke but the acrid smell whenever the oven was on continued.
We cleaned the oven, cleaned under the oven, smell still there.
So we took the oven out & took the back off.
Oh. My. God.
The back of an oven is full of lovely fluffy white insulation, like cotton wool. Except our oven was full of pissy brown cotton wool festooned liberally with rat shit.
The little fucker had got into the inside & built a nest.
BOAK!!!
The oven is now in the garden & a brand new one is coming on Monday.
That's £750 I'd rather not have spent but there was no choice.
I still feel sick.
