My rental condo has terrible cat urine smell from upstairs

Our neighborhood officer told us that a strong cat urine smell could possibly be a meth lab. YMMV. It is something everyone should know. Meth is a horribly destructive illegal drug.

Even Nature's Miracle will not get rid of all the smell, because cat pee seeps into the subfloor, as a previous poster said. As well as baseboards and potentially drywall. So that pee is in that neighbor's home deep down. Nature's Miracle has something in it that "dissuades" the cat (or dog) from peeing there again. But the cat's owner has to USE it, and it doesn't appear that the owner even recognizes there's a pee odor problem at this point -- many pet owners become immune to the smell.

I wonder if your local Animal Control would come out to verify the cat smell and write something up for you? Do you think there are several cats on the premises? Any suspicion that there's a "cat hoarder" living there? Cuz that's certainly something that would bring Animal Control out.

If I were in your situation, I would find a housing lawyer and pay for a consultation on your options. I could certainly see a lawsuit based on the other owner's failure to take suitable action, which has infringed on your "right to enjoyment" of your property -- ie, the rental income.

It's not going to be enough just for that owner to have the tenant evicted. There will be costly remediation action -- ripping up subfloors, etc., for example, or hiring one of the cleanup companies that come in after fires and help clear out the smoke odor (whatever technique they use could work on cat pee odor).
