Query: No difference!

I purchased this product since we have a new kitten in the house. We placed three bags near her litter box, and to our dismay, there is no noticeable difference in the odor. I placed all three bags in the sun for one full day to recharge, however, there was no change in the result.I would like to know what product would really work to eliminate the odor. Baking soda has worked best so far with marginal results.
