Hi everybody

Probably been asked a thousands times before, sorry, but what is the
most effective thing I can do about stopping cats crapping in the
wife's pot plants which are outside on the balcony?

Best regards

Short, sharpened bamboos, say 6" long, inserted blunt end into the soil
with pointed end upwards. if they can't lower their arses to the
ground, then you've sorted the problem. Always worked for us in the
wife's begonia pots.
