RSPB Approved CATWatch Ultrasonic Cat Repeller

Good but with limitations Review by Steve
Requires a clear field of vision to work correctly, ie will not work if planters/ large plant pots are within view. Was surprised at the limited field covered
but once moved closer to where cats were frequenting it appears to be working. Being used on back garden but may have to purchase another to
cover the front garden as that is also used as cat toilet. (Posted on 26/02/2021)

Does the job required Review by Mark
While these are an excellent cat deterrent and work really well they don't seem to last more than 2 or 3 years before they stop functioning and need replacing. I beleive it could be due to lack of protection from the weather, they don't seem to like the damp. However, cats certainly don't like them and while they are working they will keep cats out of your garden but the larger the garden the more units you need (Posted on 17/07/2018)

Further to my comments Review by Norma Parks
Further to my comments about the early ineffectiveness of the Catwatch deterrent, I need to retract my negative opinion! The deterrent was replaced by Concept Research without any difficulty and has been in constant use for five months now. Eventually my garden has become cat-free. Concept Research give a lot of information about using the deterrent on:

CATwatch - the RSPB approved ultrasonic cat deterrent to keep cats away from the garden.
As described by the manufacturers, it does take time for cats to react and move elsewhere. For anyone thinking of buying a Catwatch deterrent read the information and have patience. (Posted on 21/10/2016)

Device not effective. Review by Norma
Range less than 3m and very narrow angle to trigger device. Cat fouling within two metres directly in front of device. Have discussed ineffectiveness with manufacturer and have returned it to them in Stevenage for their opinion. (Posted on 14/04/2016)
