Well the site says it can be use as fertiliser but doesn't say after
the cat used it... I believe it means unused and it is just stated to
tell you how natural it is and blablabla.... Cat pee is very strong
and would not recommend that... although I am no gardener or pee
analyst, if the product really neutralise the amonia it might be
possible, try it on a small piece of your garden and see... I
personally use wood pellets
