Maybe you could clean it as good as possible and then seal it. Sealing it
might trap in the stink and prevent any other stinks from penetrating it.

I have an unfinished room in the basement level of my home, and one
of my cats (now deceased) made quite a mess on it deficating and I
can't find a product that will clean the stains. Any heavy-duty
cleaners I find for concrete are for garages, etc. What is a safe way
to clean deep stains indoors that won't hurt pets?
