My friend has a liquid feed problem; his is with cats.  He tells me that it kills his plants dead, and I'm sure he said you couldn't eat the plants either, though if they died before fruiting, ach.  So I've heard cats can be bad for yer veggies, or more specifically cat's pee.  Am I harbouring an unnecessary negative here, cat people?  Or do you have to train the cats to keep away from the veg. area?
