The first thing to say about this CAT Watch ultrasonic deterrent review is that having now owned and tested the device for 2 years, I have updated much of what I originally wrote after the initial trial period.

 

The second thing to say is that it is the dearest of these type of cat scarers on the market which is probably why I put off buying it for so long in the first place.

 

Of all of the ultrasonic cat deterrents I tested, this was the only one that I was able to leave in its original position. The cats soon became accustomed to Defenders Mega Sonic and others I tested and several would just ignore the devices after a month or so unless I kept moving it around to keep them on their toes.

 

The CAT Watch though is in its original spot 2 years later and still keeps them out.

 

The photo below shows one of my problem areas. The garden sloped dramatically in this corner as you can tell by the fence on the left which followed the slope down and this was why I put in a raised deck. The fence on the right is at the bottom of the garden and is 1.8 metres high looking at it from the other side.

As you can also see, there are trees on the other side of both fences in this corner so it was an ideal spot for cats to gain access to our garden.

 

In the picture on the right you can see I placed the CATwatch ultrasonic deterrent on the deck post near the steps that lead up onto the main decking area and on to the rest of the garden.

 

In that picture you can also just about make out the lead for the mains adaptor which I highly recommend you get with the CATwatch if you have an external socket as not only does it mean you can just plug it in and forget, you also won’t have to worry about plants swaying in the wind constantly activating it and running down the batteries – a problem I had with other ultrasonic deterrents.

 

You can also see in the background that the deck has standard balustrading but I swapped it out in this corner for trellis so that any cat coming in at this point had to go up the two steps to get any further up the garden.

 

This means they have to go past the device when entering here. It also means that when it activates they would have to run towards the noise if they were determined to get into the rest of the garden.

 

Does It Work

 

It works extremely well – and is perfect for problem areas where a water spraying deterrent wouldn’t be practical, such as in a corner where I have mine permanently set up. I would estimate 9 out of 10 cats that drop down onto the deck and trigger the device will instantly jump back onto the fence and disappear on the other side.

 

Like most of us, cats can lose their hearing range as they get older so while CatWatch is never going to work on all cats, its success rate is higher than other ultrasonic deterrents I have tested and is only second to the Contech Scarecrow.

 

About the best thing I can say about the Cat Watch Ultrasonic Deterrent is that if mine were to stop working due to age, damage or whatever, I would instantly order a new one. It has lasted over 2 years already so has solved one of my problem areas for a cost of less than 50p a week!

    I made a device I named “scare a cat”, to keep cats away from my garage. It has a PIR sensor, which activates a 4MHz clocked picmicro by interrupt on high level on a pin, which in turn sends out a 20 to 30 kHz series of square wave signals (I think in 13 steps, if I remember correctly), amplified by a 12V BJT amplifier with gain of about 4, to a piezo horn tweeter. Cats have stopped visiting. The thing is powered by 12V lead acid battery. picmicro is at 5V by 78l05. Amplifier gets powered on and off a few microseconds in advance and aftwerwards, by a mpsa06 NPN bjt on ground, so that circuit only draws about 3 mA in standby. I guess anyone with some microcontroller programming skills can build one too. Or use an Arduino, which does not need any hardware programmers either.

    Sounds very intriguing. I have absolutely no experience in building something like this, but plan to research where to get the components and try! Thanks for the details.

    We have a bush type tree in the boundry line between us and our neighbour this is the home for many (20 – 30) small birds throughout the year. I put down fresh bread cut into small bits every morning and it is a pleasure to watch the birds swop down and feed. Just lately they have stopped feeding though still in the tree. We also have a small garden pool that is the home for frogs. There are two cats that always come into our garden over the year we will have dead birds and frogs left on our pathway / yard. One cat in particular sits beside the pool even goes down the stones around the pool to get nearer to the water. The cats watch our kitchen and patio windows and when ever we move to the window or open the kitchen door they / it run off but not out of the garden we have to physically run at them or threaten them by pretending to throw something. The cats do not belong to the seven properties that we share a boundry with.

    They access tha garden from the house front under the side gate, or over the 6 ft high wood panels on the left and rear fence or through the neighbours wire mesh fenc at the top right hand side of the garden. There is narrow path at the side of the house that gives access to the rear that a sonar device could cover but we have no outside electricity and does not get direct sunlight . Another dead bird this morning and not one of the small ones, obviously eating the bread left out opguring the night. I have considered chicken wire around the pool but would look unsightly. do you have any suggestions please

      Don’t feed the birds on the ground
      buy some feeders put seed inside use a feeder with a cage so that if a cat does appear the birds will be safe.
      Birds should not really eat bread its not good for them.
