Apparently they hate pepper so you could dust a bit of that where they usually go. Similarly they also don't like citrus so could sprinkle some lemon juice etc on the path.
We have circa 8 cats who come into our garden and leave their calling card but our garden is big so no amount of pepper will deter them as they find a new spot but if your path is fairly small it's worth a try.
Hi out there, I'm just wondering if anyone has a good method of keeping cats out of your garden? They have a habit of pooping all over my garden path (it's an enclosed garden so it can't be a dog). I cleared it last week and they are back and it's worse than ever! I have a young child and worry she'll pick it up. I have bought one of those devices which emits a noise that they apparently don't like, but it appears they are immune round here. Short of getting a dog, what would you suggest?
