Hummmmmmm and here I have been trying to discourage cats from using my vegetable and flower gardens as a cat box. If that is the system why not just cut of the middle man, dispense with the litter box, and let nature takes course? Unless of course the cats don't go outdoors which I guess might be an issue some places.
I much prefer my organic fertiliizer not quite so ripe. I do not enjoy finding clumps of stuff clinging to my feet whether with or with out shoes.
The cats here are sort of odd.
The ones who are mostly "indoor" cats like outdoor plumbing.
The ones who are mostly "outdoor" cats like inside plumbing.
But it works; this is a pretty big property, with several gardens first planted during the 1880s.
Myself being no gardener, every spring I just let what wants to spring up, spring up.
Broccoli and cucumbers is about all that I swipe out of it, though; the rest, I let sprout, grow, ripen, and then rot back into the soil.
