HELP NEEDED!!! Cat filled house - Cat urine removal ceramic tile

[Casey Hunt]

All, I bought a house that has had cats living in it for a while with no owner. I was told about 25 cats. so you can imagine what the house looks and smells like. the entire house has ceramic tile. I assume the tile is ok but the grout has probably absorbed a majority of the smell. Is there a way to clean this to the point of no smell? Will I have to remove all tile, if so, what's the best way to remove it. Any help would be greatly appreciated.

Spend a few days removing most of the grout between the ceramic tiles with a grout removal blade on an oscillating tool. Install new grout and seal. Pull all the floor trim. Cut out the bottom 12 inches of drywall throughout the property . Paint the 12 inches of studs behind the drywall with Kilz Original Oil-Based primer. Replace with new drywall using screws and drywall clips. Finish the drywall, paint the wall, install new floor trim, paint new floor trim.

If you do this and the cat stink is not completely gone forever, you might as well walk away, because you'll never get it out.

I have 3 cats and one of them has had recurring bladder infections throughout her life. I know whereof I speak.
