If you want to stop cats using your garden as a toilet then a cat sonic repeller might be your solution

So I was looking out my kitchen window a few weeks ago (overlooking the lawn at the back of our house) when I saw one of several neighbourhood cats settle down for a nice relaxing poo in one of my garden borders, right next to my emerging hostas. A sharp rap of the window was all it took to send this pesky feline running on this occasion. The next day this cat came to the same border and settled down to do his business. This time it took several hard raps of the window pane and some yelling and frantic arm waving to send the stubborn moggy on his way. Now the same cat doesn’t even look up once it’s settled down for some time out and I have to run into the garden wailing incoherently. The hostas aren’t doing so well this year and this could be why (any gardeners out there who can advise on this? Cat urine and faeces can’t be all that beneficial I would imagine).  Another rather scruffy looking black and white cat thinks it’s alright to do the toilet underneath my kids’ trampoline. Actually, it seems that at least four neighbourhood cats and probably several foxes are now using my back garden as a toilet. The other day I saw one of these cats snacking on a sparrow (also frequent, but more welcome visitors to my garden).  I wanted to know how to keep cats out of garden areas and so I started looking around for (harmless) ways to show these determined animals that enough is enough.

It seems that there is a range of methods and products available to keep cats, dogs and/or other unwanted visitors away from your garden from chemical means (sprays and pellets such as Keep Off Cat/Dog Repel by Secto) to physical methods (sprinkler systems such as the Jet Spray Water Repeller – to detect and repel cats, dogs, birds and squirrels (probably foxes as well – I’m not sure about people) (not so great for me because I would like to keep birds coming to my garden) and ultra-sonic cat repellent devices to detect and repel cats and other unwelcome visitors to your garden. These devices can be strategically positioned in your garden to protect particular areas. Several of these ultra-sonic cat repellers (and other animal deterrants) such as The Big Cheese Cat Repeller require no wiring and can run on batteries although performance is probably better if they are run from the mains. Others are mains powered but can protect areas as large as 200sq metres – Gardman Cat-Gard Green.

I finally chose the The Big Cheese Cat Repeller because I’m not great with DIY and outdoor wiring is not something I relish. It’s also the top selling device of it’s kind on Amazon.co.uk with more than 330 reviews scoring an average of 4 out of 5.
