Can you tell me if urine, particularly dog and cat urine, is high or low PH? I'm assuming it is fairly acid, thus I've not discouraged the cats and dogs from peeing on some of my acid loving beds although I do dilute it fairly quickly. It's hard to grow acid loving plants here as the soil and the water are very alkaline, I live on a limestone shelf. I also put coffee grounds and such on the plants but I'm hoping the animals are helping too.
