A neigbour of mine has a problem in that a cat(s) probably is own is going
to toilet in his flower beds in the front of house thus causing a smell.  He
has had to get rid of the soil, for those who live in America I must mention
that the area in question is in UK and where we are located there is not a
great deal of space.  He asked me how he could deter said cats from using
the soil, my suggestions were as follows, put something over soil, tree bark
etc., or fill small bottles with water in the hope that the reflection will
scare the cat.  My grandmother used to put small pieces of bamboo in the
soil so the cats could not squat on the soil, the only thing I ever did that
worked was cover the soil with clay, which is in abundance where I am (very
small area of soil though. My neighbor is not that fond of cats but the rest
of his family are, he is more into growing flowers, has anybody got any
suggestions that I can pass on to him.
