Pestbye® Battery Operated Cat Repellent V2 - Easy To Use Ultrasonic Cat Scarer with HyperResonance Frequency - Set of 2

Was effective straight away. No cat mess since.

So here's why I "don't like it" (thats what the two star rating says, not me personally) just one day after excitedly setting it up. A perfectly piled pile of poo appeared in my flower bed overnight. I spent months creating a tidy space in the back garden of my new home. As soon as the flower beds were created, an invisible intruder starting making a nightly deposit which I faithfully picked up and disposed every morning. Then I researched cat repellents and after several failed sprays and other natural options I finally found success. I cluttered up the beds with cut branches of holly and rose stalks. In between this I laid out a few brooms, some long twigs and a solitary prickly potted plant. While the arrangement happily didn't suit the intruder, the flower beds looked like a garbage disposal site. Not quite the look I was going for. But the deposits were rare. Yesterday I was excited to set up the Pestbye equipment and it appeared to be sending the signals at the correct angles. I left one bed full of the cuttings and clutter and cleared the other beds, making them nice and beautiful. Just to help the Pestbye, I also sprayed some "Doff Cat and dog" repellant spay on the beds. Surely that would be enough. NO, it wasn't :-(( This morning the cluttered bed was clear, but there it was, on the clear bed, in the morning, proud and piled high. "Its" shape was one of an "unhurried" effort. Today the cuttings and clutter have gone back on the bed. I will leave the Pestbye there for a month as instructed, but if there are no further deposits, I'm not sure if I can give credit to Pestbye , or to my unsightly prickly collection.UPDATE(19/08/16) :I changed the angle and positioning of the two units and added more holly cuttings. No cat poo in sight :-) However the next day the familiar stink rose from the other side of the garden in another bed :-( I filled it up with holly cuttings and no Pestbye yet and no cat poo there either.UPDATE : 06/12/16: Huge poo in direct sight of Pestbye unit, where holly cuttings blew away in recent bad weather. Deeply dejected :-(UPDATE : 10/09/16. I figured the sound must irritate the culprits, but maybe the cat was eluding the motion sensor. So I "planted" 2 sets (4 units) in plant pots at opposite ends of the garden, with the plant leaves activating the device when the breeze moved the leaves in the plant pot. I also cleared away the rakes and spades and sticks from the beds (not the holly cuttings just yet) to see what would happen. 2 days -no "deposits"! I turn off the units in the morning, and on at dusk. Lets see how long the batteries last. Fingers crossed! Rating updated to 3 stars todayUPDATE: 27/09/2016: Not a deposit in sight!! I think we have a result..So the key is the outwit the cat, by keeping the unit sporadically active using the swaying motion of leaves of a potted plant or shrub-in 4 different locations. Yes it will mean more battery usage, but with nothing horrible and smelly in sight I think its worth it! ( I saw an almost lynx size wild cat go around my garden and across the road one early morning last week! Wonder if this was my worthy adversary!) rating updated to 4UPDATE: 26/11/16. Its cold, so I hardly go out, but when I do I don't seem to smell the cat deposits like before. This afternoon I peeked out and look who I saw sunning himself (picture of offender..(finally!) enclosed) Grrr..This after I have 4 units installed. One unit visible flush against the fence. Should I check the beds ..or keep calm till spring..hmm..

So I’m truly torn on how to review this product, you could say I’m on the fence…. ( get the joke!… if you don’t see the picks)On one hand the cat poop has stopped but on the other hand we have had some cats still in the garden and they appear to be having a “chat” when we came home the other day.I’m not sure if this is a strategical talk on how to disarm the devices or just a casual chat amongst feline friends , either way I’m on alert!They were by the garden ( on the fence ) but not in the garden so it must be working…right…. After one cat legged it I did a “test” to see if the other cat reacted at all to the device…. It didn’t. However the poop has still gone and I’m happy about that.What I can say is that this product is slightly different to the neighbours ones I have seen and heard. This one does a slight ticking noice and what I can assume is going up and down the ultrasonic wave lengths which unsettles the cat.Upon reading the product info this one is different to most as it only goes off when it detects body heat. Most go off with movement be it a living creature or a bush moving in the wind. This then shows the cat that it is their presence which is making it go off, thus deterring it from being near the machine. It also saves on the batteriesTop tip is to move it about a bit so the cats don’t know where it is all the time.It works as we have a lot less poop now in the garden , we were having to clear up everyday , now it is every week or two. Slow but surly it’s stopping the habit from the next door neighbours new cats.Would recommend

Stopped working after 2 months,

The device has rounded rather than sharp edged stakes and so are not easy to push into the ground. I decided to tape them using strong duct tape to two garden posts, set about 7 foot apart. When I moved in front of the devices in the dark, I could see the round detectors on them glow red and heard them making a rickety noise. So, they seem to be working? But did they repel the foxes? Well, a couple of days later I found that BOTH devices had been wrenched from the posts and were now a few feet away on the lawn covered in mud. Another deep hole had been dug in front of the pillars (perhaps in retaliation?). Clearly the fox had become maddened by the annoying noise in their ear drums and decided rather than run away that they would tackle the problem head-on by attacking the devices. It would have taken a bit of effort to remove them from the posts because the duct tape had gone round the whole of the posts. If I had inserted them into the ground then I am sure the fox would have pushed them over or dug them out much more easily than it was to tear them from the pillars where they were taped. So, these devices do seem to make the foxes uncomfortable ( or annoy them, even) but city foxes are now so bold and brazen that they will defend spaces that they have come to regard as their 'own' rather than just go somewhere else. Maybe these devices should come with screw holes so they can be securely screwed to garden fences, to stop foxes from taking them away?
