For a permanent fix, apply a puddle of straight bleach to remove any discoloration. It should kill the odor too. But before sanding and resealing you might want to apply one of the proprietary odor-removers sold in pet stores.Jul 7, 2006
Why is my hardwood floor discolored?
Discoloration of wood flooring is often caused by rugs on the floor. If the oily residue is gone from the surface and the floor is still discolored, then oil has seeped into the finish and the floor will need refinishing to correct the problem. Discoloration can also be caused by the finish darkening with time.
Why do my hardwood floors look blotchy?
If your stain looks blotchy or uneven on your floors, it was probably caused by poor application technique or poor wood preparation. If your floors have not yet been coated with lacquer or varnish, or have already been stripped of any topcoat, you can even out the stain by sanding and then applying more stain.

How do you fix a sun stain on wood?
If you're only sanding the sun-faded sections of flooring, use a 120-grit sanding block. Sand the area until the finish and stain are removed. If you're having trouble getting it off, try medium-grit sandpaper and then use fine sandpaper to smooth it out. When you're done sanding, it's vital to vacuum up all the dust.
