Every single pet store is out of every enzyme cleaner?
I used to use Nature's Miracle til I found Get Serious which is a stain, odor and pheromone extractor and is awesome! You can get it at PetSmart.
If no stores carry anything, perhaps you can call a carpet place and they may have something to get you by for now but it will be expensive. I believe Target and Walmart carry things that would work.
You could also order online and have it shipped priority.
There is a home-made tip! Vinegar is good in washing catpee from fabrics. take a big spoonfull of vinegar and 3 spoonfulls of water and add what ever you are using to wash dishies manually. It should do the trick. I also use vinegar if I have to wash something with catpee on it.
Vinegar doesn´t smell roses, but while it evaporates it takes other nasty smells with it.
