How can I stop cats from poohing in my garden?

Get your mother to suck its asshole dry.

Buy a cat alarm works after 3 weeks

Orange peel, vinegar or coffee grounds.

Plant a pot of Catnip or some Mint.

I have a system that works. I trap them and attach a note to their collar that says "Next time I catch your cat crapping in my yard, he's going along with me on a trip to Las Vegas, and WONT be coming back"

1. Get a dog.

2. Get a pellet gun.

hi scatter lots of lemon peel down around the garden.

Get some fresh Lion Dung or some "GET OFF" spray from the pet shop. It is usually FOXES that get into your yard. Most cats are INSIDE at night, rarely are cats left out all night by owners these days.

There are all sorts of cat repellents, all of which claim to have near miraculous properties in dissuading them. When we were catless I found that lurking in the garden with a high-powered water pistol did the trick. It doesn't harm them but they hate getting the fur wet so they stopped coming. You do have to be persistent but it's also fun in that it improves your marksmanship too.

Now we have cats again and they deal with trespassers very effectively. They seem to be able to detect a stranger even when indoors, and they'll go on the alert, one or other or both will rush outside and you can hear the kerfuffle before they stroll back in looking smugly triumphant.

My Dad used to put ginger on the ground as it supposedly warded them and it seemed to do the trick.
