Cat watch Ultrasonic Deterrent

Definitely works, although the batteries need replacing quite frequently - we're going to invest in a battery charging station and rechargeable batteries because of this. Has drastically reduced the amount of cat faeces deposited in our garden by the neighbour's cats, who previously treated our garden as the neighbourhood toilet - pretty disgusting and annoying considering we do not own any cats ourselves, yet had to keep clearing up after them! God-knows what they were feeding them too, since what was left was truly revolting. However, thankfully these devices have made our lives much easier! They are expensive compared to similar products from other manufacturers, but we went with these because they are the only ones certified by the RSPB as not being harmful to any other species - we didn't want to harm birds or the resident hedgehog. They do work, but like I said make sure you replace the batteries when they fail, otherwise the cats will just continue being a nuisance. Also, be aware that you may need to wait a week or two before you see improvement, AND remember that they need a direct line of sight in order to be effective - shrubs/trees/structures will block them.

Worked for a while; and appeared good. Then despite all new Duracell batteries, and testing all new batteries, was unable to get it working. Was stored away for winter, as wondered if the cold was an issue, but on retrying this week with new batteries, and testing batteries yet again, did not work. Could not cover any radius at all. Really needed this too work, bought specifically for cats, as do not want to disturb wildlife. In saying that, other reviewers appear to have got good use from this deterrent over some time. And if working well, and positioned in a danger zone, is a positive move for the birds.

Great product haven't seen a cat in weeks still early days though but seems to be working well

FURTHER UPDATE 21/9/2020......I have taken this down to 1 Star........DO NOT WASTE YOUR MONEY ON THIS if you think it’s going to work on every cat that visits your property! It doesn’t! I decided to update my review after having this device a few months and seeing how it works. Yes, I’ll admit some Cats don’t like it but it’s expensive and in my humble opinion, should work to deter EVERY CAT! UPDATE 9/3/2020......I have started to hear the noise emitted by this device, very odd because I couldn’t in the beginning?! I’ve just put a NEW Duracell Battery in it, thinking it might be that. But no! I can still hear a noise! And unfortunately I’ve seen Cats visit who aren’t bothered by it whatsoever! So, I’ve taken 3 stars off my initial review, which was probably a bit too soon to post really. I might contact the supplier to tell them and perhaps ask for a refund on the 90 day refund policy. This wonderful product works really well! Cats have decided to come onto my drive and leave “presents” and I was getting totally fed up of trying different sprays/pellets etc. Until a friend told me about this Ultrasonic Deterrent. I’ve probably spent as much as this costs on the sprays/pellets!!! The FIRST evening I put this outside, within a couple of hours it successfully scared a Cat away! So very happy......it may be small but packs a punch as far as Cats are concerned 😊 It only makes a faint clicking noise when it detects movement.

Battery doesn't last long. Effective whilst it works. Randomly stop working.

I didn’t expect this to work, having tried several other cat deterrents without success. Most days we were plagued by local cats using our lawn as a toilet. But two months on from installing our first two of these there has still not been a single turd on the grass. Amazing! I bought two more and now have one at each corner of the lawn. I changed the first set of batteries early, as a precaution, after about six weeks. They seem expensive for what they are - presumably the cost includes a charitable contribution - and the set-up is a little fiddly (grease on the terminals and anti-fog coating inside the sensor screen. One needed immediate replacement (its range was too short) but that happened promptly without quibble. But overall these have been an excellent purchase - worth the cost. So far they have performed as promised and I am very pleased.

Had my garden re done in autumn, so lots of bare soil which local cats used as a toilet. We were picking up sometimes 10 or 15 poo’s at a time. Got one of these and after about a week there was only 1 or 2 poo’s. After a few more weeks they don’t come to poo at all anymore! The rain affects the sensor so I made it a bonnet with a plant pot which has solved the problem. I’ve had it since October ‘23 and haven’t had to change the battery yet, despite the sensor being triggered at least 2 or 3 times a day as we walk past it to our cars.
