CATwatch - the RSPB approved ultrasonic cat deterrent to keep cats away from the garden.. COMPLETE with AC adapter Kit

Remember the song " Anyone who had a Heart" ? Well, anyone who has a cat crap problem has a big one, because the deterrents you come across on line DO NOT WORK!!! That includes most of the "Ultrasonic" deterrents and , in my experience, ALL of the sprays. Once those feline faeces makers latch on to your garden as the ideal loo the word spreads, and so does the poo. You name it, I've tried it and the cats ignored it and left me their blessings. In a final push I placed gravel over a 10 meter area they favoured, after removing the top soil and sanitising with disinfectant . The result ? The bigger cats managed to scoop the gravel over their offerings, the smaller ones just left them on top. Then the sun came out and sitting on the patio became a no no . Then I saw an article about CatWatch, recommended by the RSBP, and I have a lot of birds in my garden, so I thought this has to work, because no organisation is going to recommend something that doesn't work . The downside was the price, the upside was that for that much it HAS to work, AND IT DOES. The battery option will give less performance as the battery drains, so go for the DC option. Over time you will pay LESS as batteries are not cheap, and the recommended variety is the most expensive. You get what you pay for. Unlike my feline friends who got what what they never expected. PS. The cats are still there, but where? Maybe you've had an increase in feline footfall?

Not good. Cats still come into garden don’t seem deterred at all by it. Not worth £70. Money wasted.

It does take a while to get the hang of these. They are not the kind of thing that you can just set and leave. People might tell you that they didn't work for them, but they probably didn't persist with them and figure out how the cats relate to them. It takes a good few weeks for cats to realise that their motion is connected to the noise. Then cats will figure out ways to avoid setting off the alarm. But using them has completely changed my garden and gardening. I recommend the wired version rather than the battery version as it's possible to not realise the batteries have gone dead and wind etc can use up the battery. The RSPB give a long guarentee and I had a no quibble replacement after one went wrong after 18 months. I can't recommend these enough. I would add they the devices don't work for deaf cats.

OK, so I was sceptical about the probable success of this device, so I bought only one unit and a transformer unit (rather than forever needing to change the batteries) to test its results. After all, it's not a cheap unit.We have a 100ft garden and it's terraced so I knew it was only going to cover a section, so I picked a high catraffic zone and considered the angle of sensor coverage in its placement. A few days later I did witness one of the dozen+ visiting cats baulk as it approached the sensor, look puzzled, and then when it moved again (and the sensor had presumably reset itself) it bolted off to the side and through the hedge. I presume it had responded to the device's noise. Fortnight in: Cat poop = nil, Catraffic notably reduced.So I laid out on an extension cable and second unit to place further down the garden to cover the middle level and bird feeder area. Now catraffic is down to rare scoots across the garden to leave as quickly as possible. I believe, however, that power for the second one being supplied via a Y connection on the extension cable from the first, perhaps reduces the effective reach of the second sensor, but it seems to be working otherwise.This not-so-cheap product does work, especially if you consider the optimum positioning. For better success in a larger garden you may need to buy more units + extension cable or second transformer. Personally, I'd shy away from the possibility of regular battery changing in them.

Edit - the pesky moggy worked out how to get in the L shaped garden without setting the scarer off, so I've bought another one.We've got probably one of the best local gardens for cats - plenty of places to hide and birds to watch. Trouble is they're not welcome. I've tried a few things to get rid of them but one has been especially persistent. All the usual stuff - peeing on plants, pooing in borders and trying to catch birds. It's just not on!I had a mains powered cat scarer many years ago, and a few years back bought a solar one. Don't buy them unless you want to keep cleaning and recharging it and even they they're not much cop. I bit the bullet and bought this one, with the mains power supply. Fingers crossed, I've had one parcel and no other evidence since. That said, I've also blocked its main entrance into the garden and put hawthorn off-cuts on every patch of bare soil that there is. I don't doubt that it would have come back, twigs or no twigs, if we hadn't had the cat scarer. And the birds are coming back now. I'd call that a success, at last!

I was annoyed that when this product arrived it was not working properly so we had to return it - at our own expense - to the manufacturer. For this reason I would not use this vendor again.

It is not a perfect solution but it does seem to have reduced cat visits to the garden. In the winter it seemed to stop working under very wet or cold conditions, however most cats seem to hunt less at that time of year. Now that nesting season is on us I see less of the local petty cat. It stays to the back of the garden usually where the vegetation prevents the cat scarier from picking up its movements or body heat. I have seen the cat crossing the lawn once so I am a bit concerned that cats can become habituated to the sound but time will tell. The scarier is worth a try when you have tried everything else and nothing has worked
