Hello,

There seems to have been an increase in the local cat population. At
first I tried to adopt a live and let live attitude but now cats are
sitting on my car, scratching at the fence panels, and going to the
toilet. Things have got so bad that I have dug up a couple of
flowerbeds and replaced them with gravel....

Cats like pea gravel even more than soil, so I hope you used at least
20mm grid chippings.

Ammonia seems to be another suggestion and Jeyes fluid. Again Idon't
know how volatile these are and the ingredients in Jeyes sound almost
as unfriendly as the cat litter!...

While wet, Jeyes fluid is highly toxic to cats, although it is safe once
dry, so must be used with care, unless you fancy a visit from the RSPCA.
I found it very useful as a dog repellent on an open fronted driveway,
but the cats didn't seem to notice it.
