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

Fabulous! I didn’t write an immediate review because I wanted to wait the month to see if it worked. Then I forgot! But I have just recommended it to my daughter who is being plagued by squirrels in her garden. I have ordered two for her. It will be interesting to see whether they work as well with squirrels. As described, in our garden the cat scarers did not achieve the complete removal of all cats in the first month. Suddenly the huge numbers of cats in our garden became completely conspicuous by their absence! We bought our two units in July 2017 and after the initial period there has only been one cat seen in our garden and this was when we forgot to replace the batteries!!! No more of the copious amounts of cat poo! No more dead birds in my garden! No more fighting cats and accompanying vocals under my window! Great! Really works for me. This animal lover had become a cat hater. Now I can love them again, from a distance. As described previously I bought these for my daughter who is inundated with squirrels. Sad to say it did not work as well for her as it did for us. The cats couldn’t hack it and we have remained a cat free zone. The squirrels sadly are not too keen, but the spoils of bird food are so tempting that they have been able to ignore most of the sound emitted from the device. So in summary, an amazing cat deterrent but not so good with squirrels. I suppose the cats still have to catch the birds, for the squirrels, the bird food is there for the taking. They are clever enough to realise that.

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 today UPDATE: 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 4 UPDATE: 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..

These work better than I'd thought they would. Have kept cats off car and garden. Used rechargeable batteries which depending on much cat traffic tries to pass they last about a month before recharges.

Well these work great to deter cats the first time you put batteries in, but they DO NOT withstand weather, even in sheltered areas. I have put a 2nd lot of batteries in and they are making a funny sound and a cat stood there in front of the sensor the other day and just looked at me as if like 'well your silly sensor doesn't work anymore!' So to spend that much money for approx 3 months of use.... no thank you. I have gone through many of these sensors before from other retailers and they just do not cope well in rainy weather. The screws are also so tiny so difficult to remove back to replace batteries. I'm not going to pay the money anymore for these, the dog will just have to bark when the cats keep using the passage way to cut through and we will just have to watch out for cat poo if we use the passage way. I WOULDNT RECOMMEND THESE UNLESS YOU WANT TO PAY TO REPLACE THEM EVERY 3 MONTHS WHEN THEY STOP WORKING!

We live in a neighbourhood with many cats. We do not own a cat. Most of the neighbourhood cats like to use our vegetable garden as a litter tray, particularly at this time of year when few plants have established. We try everything, stakes at angles, cat repellent powder and several cat scarers. Our last one lasted 2x years which was reasonable as although they are "weatherproof" IP44 isn't enough to survive many winters. We've had solar ones but the solar panel always dies. Bought these as a pair to try to cover all entries. They state it can take a few weeks to be fully effective as cats poop in a routine. Initially the cats pooed again but they now appear put off. They disturb the earth but no droppings currently. Using in conjunction with repellent powder. Longevity will be the question. So far I'm reasonably happy.

It stopped the cats from pooping in our garden

I got these based on both reviews, and the technical information by the manufacturer (seemed to make some sense). The do work, but as others have mentioned, you do need to place them well. I found, by experimentation, that you have to take time to find just the right spot to place them. It does seem they they work better as a close pair (angled at roughly 90deg), rather than positioned apart from each other. For sure they don't completely eliminate cat movement, but they have certainly minimised it. I no longer get the regular visitor sitting under the hedge watching the bird table. I found the best position was pointing closely at the entry route in the corner of the garden, where it jumps down from the fence. One disappointment was the fact that they use normal batteries, rather than being solar rechargeable. Although I wonder if that is a factor in them working slightly better than those models - perhaps a little more power from the sounder. I bought GP branded Lithium AA batteries to try out at the same time, and they're still working fine since I bought these in March 2022. My intention is to have less bother replacing them, and to not have to dismantle the backs as often. Overall, these are OK, but I don't think they're a magic wand, I'm not sure any of these sonic scarers do much different between them all, you just need to be patient, and be prepared to experiment with placement.

Well I've left it a couple of weeks before writing a review. I'm impressed they seem to be working for us. Hence the five stars.

Didn’t help

Avevo già un prodotto simile in un punto del cortile adiacente alla mia abitazione e ne ripresi altri perchè li trovo funzionali all'obiettivo di allontanare i gatti randagi.

Beaucoup de chats dans les environs et toujours des toilettes dans notre jardin. Mais plus maintenant, ces ultrasons Chat Pulsbye de Répulsifs sont parfaits. Certainement les acheter.

Da die meisten Nachbarn Katzen haben, nur wir bedingt durch zu wenig Zeit keine Haustiere halten, wurde unser Grundstück von den Nachbarskatzen leider zum Katzenklo der Umgebung gewählt. Dieses lästige Übel hat sich durch den Einsatz dieses Katzenvertreibers nach ca. 1 Monat nun endlich tierschonend erledigt. Allerdings muß man Geduld bringen. Durch unsere Außenkameras konnten wir in den ersten Einsatztagen beochten, dass die Katzen nicht den Eindruck machten, sich wirklich an den Geräten zu stören. Es wurde weiterhin lustig durchs Grundstück gelaufen. Allerdings wurde schon nach kurzer Zeit kein Stop mehr für die Erledigung eines "Geschäftes" eingelegt. Die Katzen laufen dabei nicht wirklich schnell weg, aber sie verlassen halt den Garten auch wieder ohne sich irgendwo länger aufzuhalten. Mit der Zeit regestrierten die Außenkameras immer weniger Bewegungen von Katzen in unserem Garten. Nach ca. 1 Monat waren wir dann so ziemlich frei von Katzen - man sieht sie ums Grundstrück herumstreichen aber sie kommen nicht mehr aufs Grundstück. Also bevor man zu schnell die Flinte ins Korn schmeißt, die Teile ca. 1-2 Monate stehen lassen und beobachten was in der Zeit passiert. Hier noch einige Tipps zur Positionierung der Katzenvertreiber: - Position so wählen, daß die Tiere sich seitlich nähern, dann reagiert der Bewegungsmelder besser - Der Bewegungsmelder springt schon ab einer Entfernung von ca. 6-7 m an, man kann ihn also ruhig in einer entfernten Ecke positionieren Positiver Nebeneffekt dieser Katzenvertreiber nach ca. 2 Monaten: Unsere Population an Vögeln im Garten ist enorm gewachsen. Auch brüten jetzt Vögel bei uns im Garten, da sie nicht mehr von den Katzen gestört werden.

Lo compre hace un año, lo tuve todo el verano y no sirve para nada. Los gatos como si nada, emitía el ultrasonido perfectamente pero ni se inmutaban. Un dinero tirado.
