Or you can use a neutralizing enzyme made specifically for cat odors (search online or ask your vet).

I have ripped out all of the laminate, as that was the worst treated it is enzymes, vinegar and water scrub, then sealed with BIN primer.

@Justin Jacques  It may be too deep to help, but there are several urine removing enzymes sold at pet stores by the gallon for about $25.

Chlorine constantly escapes through the plastic walls of its containers. (4) The ionic structure of bleach prevents Chlorine from penetrating into porous materials such as drywall and wood---it just stays on the outside surface, whereas mold has enzyme roots growing inside the porous construction materials---however, the water content penetrates and actually FEEDS the mold---this is why a few days later you will notice darker, more concentrated mold growing (faster) on the bleached area

I have had luck with technicians that use enzyme cleaners.

Ive looked into enzyme cleaners, and other chemicals, but havent found anything suitable for floors. 

Remove anything that you can throw away, destroy any urea crystals with a sprayed on pet enzyme cleaning product and encapsulate whatever is left with a strong primer.

I put killz all over the walls, will probably end up replacing the trim boards, and drowning the corner in some kind of enzyme eliminating solution.

Floors then got several coats of “Pet Urine Enzyme” that was picked up at lowes.

It has enzymes that break it down and neutralizes it.
