My little girl wanted a new kitty for her birthday earlier this year so we now have two cats. Maybe I just didn't notice it before, or this new cat is better at producing that ammonia smell..... I mean like walking past an anhydrous tank bad. This got me thinking. I have a lot more used cat litter now. I have heard of people using it on their property to keep the gophers and moles away but does it have any other uses. Some fertilizers are made of ammonium nitrates, would cat litter fall into this catagory and make a decent fertilizer? Could I just dispose of all our old cat litter on our garden site and have a rockin garden next year?
