Hi All
I have been a keen follower of your DIY tips as I fix up my old cottage, one thing that was causing me sleepless nights was my neighbors cats fighting in my back yard at night and keeping us awake with the noise, that whinning noise they make when they fight. Anyway I couldn't find anything in the local hardware and garden shops except liquids and sprays which I have tried before, so I went on the internet and found a great cat repellent that I bought online at
Sometimes I can still hear them fighting at my neighbors a couple of doors down but it doesn't keep me awake anymore. I hope some of you find this site useful.
Good luck with your projects
