There have been many tried and tested methods of preventing cats from entering your garden ranging from barbed wire to cat stick repellents which are inserted into the ground, yet the cat(s) will still keep on coming back!

A new technology has been introduced onto the market which uses a high frequency noise when any foreign object is detected. This noise cannot be heard by humans but distresses any cat that hears it.

There are many on the market but I would highly recommend The Big Cheese Cat Repeller which you can purchase from Amazon.co.uk. Its priced very well and it does the job!
