I wouldn't worry about it at all, unless the poo-to-soil is much higher than I imagine. I get all kinds of creatures roaming about my property, none of which abide by the "no carnivore poop in the garden" rule.

If there is any risk, root crops, and 'low growers' are ones to avoid. Mulches help to avoid soil splattering up onto leaves.

I agree with RGreen, enough time has passed that the waste is breaking down and pathogens that live inside the animal have been exposed to the harsh outdoors for months. If you are worried, avoid root crops, but salad, peas, and cabbages should be fine.

3 months is enough to get rid of harmful bacteria like e coli. As for parasites, if your cat is healthy and up to date on shots, hopefully there are none. I would not worry about it too much though. If you 'cleaned it up and removed the soil' there is not much of anything there to worry about. Always wash your vegetables anyway. You might be surprised at the number of microbes in a teaspoon of soil, and some of their names.

If you want to read more about pet manure, search for that phrase in this forum.

Thanks guys for your helpful answers. You've really made my planting today stress free!
