Cat Deterrents

Dear Harrod

I wonder if you could advise me re cats fouling in my garden.  I have tried various products which claim to stop this but the problem still persists and is getting worse.

What products can I use to clean round the area/plants where the fouling is taking place and are these safe on other plants?  The problem is male cats are spraying onto the plants and are killing off some established shrubs which I will have to remove. 

Are there any plants I could put in the garden which the cats do not like so as to stop them from entering the garden?

Thank you

Beth Barrie

Dear Beth

What a horrible problem – you have my sympathies.  The first thing I would do it dig out some of the soil where the soiling has taken place.  Cats are creatures of habit and once they have fouled an area,  the smell entices them back for more.  If you can remove the trace it will  help to stop them returning.  With regards to preventing them from entering your garden, there is a plant called Scaredy Cat (Coleus Canina) which alleges to deter cats from the surrounding area.  I have friends who swear by it and others who have not noticed any difference.  It may well be worth a try.

In the Kitchen garden we have had some success with ultrasonic devices which emit a sound that pests dislike and stops them from entering the garden.  We have used the mouse version and it has cured our mouse problem completely.  There is a device specifically aimed at cats which  may well be the answer to your prayers.  You can find this at

I wish you the best of luck.  Please let me know if I can be of any further help.

Kindest Regards
