I wouldn't use Febreeze as it will only mask the smell and it leaves a very faint sticky residue which then attracks dirt and grime.
Buy Bio-Zet washing powder. It breaks down enzymes in urine. Mix it with some water and rinse the area with this, then rinse with clean water and rinse well. If it is on a rug or carpet, I'd then use bi carb on the area and when 100% dry, vacuum off.
