5. Find ways to prevent future accidents. The more urine your cat adds to your home, the harder it's going to keep the odor at bay. So the best way to fight this stench is to prevent it from occurring in the first place. This may include any number of methods:

Retraining your cat to use her litter box
Laying down disposable, absorbent pads (like puppy training pads) in an area she continues to mark
Having her spayed (or neutered, if a male cat)
Taking her to the vet for a check-up to see if she has any kidney or bladder problems
Treating her for anxiety, if that's determined to be the cause of her urinating outside of her litter box
Cleaning out her litter box more often
Adding extra litter boxes if there is more than one cat in the household

Companionship with a cat can be rewarding -- so can keeping a home. Don't let urine odor ruin either experience.
