I found the direction on how to prepare the solution very clear and easy to follow, however, I did not find information on how to use the product.
Tarp is great, but would be better if it covered the front lip of the litterbox (under the clip). I have an old cat who loves to exploit that gap.
My cat has some of the smelliest poo. The smell would dance through the whole apartment, which is really gross when I am talking to a client about serious topics (I'm a therapist) and can't stop mid conversation to clean the box. The charcoal doesn't take away all the smell but now the smell just stays in the box. I like the cleaner for washing the liner of the box, and cleaning after my potting training dog.
