If you have pets then this is the stuff to have in your home! I came by it thanks to a friend. She knew of it from someone who owned a horse barn and used this to clean the stalls. It's a tiny bottle or spray, only $5.00. I have the pharmacy at Loblaws order it but have seen it at Jean Coutu pharmacy!! one small bottle is worth 200 drops and you need need a couple drops in a bucket of water. We had a male cat who sprayed everything. I was afraid i would not get my damage deposit back. Washed the walls, everything and all the odors were gone. This stuff doesn't cover the odors, it actually eliminates them. This is a must in our house, always have at least one bottle of each of the drops and room spray on hand. It has a lite pine scent! Awesome stuff!
