Unfortunately I developed an allergy to cats when I was about 14, I don't mind them as animals but I don't like most of the owners near me who kick them out before they go to work and they go everywhere but their owners garden. Next door has three and they sit on my patio furniture, not a problem in the winter but in the summer if I sit on it after they have been on it I come out in a crazy pox like rash so need to wash it all down every time I go to use it. I cover what I can but even sitting on my own back door step is a dangerous business, I have tried bigger fences, pepper power and just plain chasing them out to try to train them but to no avail.
Any ideas for not harming but deterring them?
And PC that canned foam was bang out of order, hang your head in shame, coconut or not that is like putting a turd in the collection plate.
