I have a quite big garden, and cats from my area like to come to my garden and my neighbours as my neighbour just got a cat and they always play together. Basically now they come and play around my area, these two cats keep pooping in my garden, they always poop in one particular area and it stinks and i have flies surrounding it all the time. i like the cats here so i can play with them, but how can i stop cats from poopin in my garden without scarring them for good?
