Here's one for the cleaning experts out there...

I got home from work and sat down on my leather couch to one of the
worst smells ever (and surprisingly it wasn't me). Something
instinctively told me it was a rotting corpse and something else told
me it was right under my ass. Well, I stood up and pulled aside the
blanket covering the couch and revealed a chewed up mouse corpse.
Woohoo!

So it looks like one of our 2 cats or 2 dogs has left us a present.
Well, I cleaned it up as best I could. I sprayed the leather with
Lysol cleaner. Then leather cleaner. Then leather polish. If I put my
nose up to it, it still smells. If I sit at the other end of the
couch, I swear I can smell it. Perhaps the smell is just "in the air"
(or in my NOSE!), and it will dissipate and go away on its own.

Any thoughts as to what other steps I should take?

Thanks all,
Dave.
