Dont want to harm them but im feed up now of this. Weve tried everything...lemon juice, expensive low level noises machines (one got stolen by teenagers as a dare) to name a few. The poo strinks (and the wee) (cats do not bury) and ive a toddler who enjoys this mall match of green. It looks amazing now after our hard work. Please wise mntters give me more advice on what else we can do about this pest. Weve rented for years and finally escapped the rent trap so this tiny garden (think terrace house) is vvvv important to us and its being ruined. Its not foxes etc its cats. I need to know plants cats hate the smell of.
