From Azraele's link:
<<
Male mice smell a lot because of their natural scent - they produce a special scent-marking urine with a distinctive musk-like smell. People react differently to this smell - some hate it, whilst others grow to like it. >>
I'm having some trouble understanding that one!
"Oh, Marge, come and look at my new pet mouse!"
"Ewwww, Betty, it's a MOUSE! Ewwww! But...doesn't he have the nicest-smelling urine!"
To the original post, I think your wife should be sympathetic to how much you dislike the stench, and agree to part ways with the mouse. If the thing stinks so bad in one hour, it's hard to imagine a product that will keep it under control for a very long time.
