This arrived yesterday. Although I've only used it once, it has nicely refreshed my dog's bed. Really I bought it for my son's football boots - boots notoriously smell of cat wee because of the sweat and bacteria. I've tried every hack going on the Internet and nothing touches the smell. I decided I might try a pet odour spray instead because of the enzymes. Gave them a light spray last night with this stuff and it's cleared the smell up!!! It won't prevent I shouldn't think but the fact that my porch no longer smells like a tom cat resides in there is massive - especially going into the winter months when the weather won't be good enough to air them outside!
