Catfree uses powerful ultrasonic sound to deter cats from your garden.

Catfree is a compact device manufactured in the UK and has a full 2 year warranty.

The device is triggered by a PIR on the front, which picks up movement and body heat up to 10 metres away through an angle of 100 degrees and will protect up to 88 square metres.

When activated, the 5-10 second burst of constantly varying sound teaches cats to keep away from the area.

Harmless to cats and other pets and cannot be heard by humans.

Powered by 9 volt battery which should last 3-4 months or optional mains adapter.

20% louder sound is emitted when using a mains adapter.

Mount in the ground using the supplied spike or fix to wall, fence or shed.

Operates in all weather conditions.

It works! I have an older poorly cat who started to mess at the back of the car port so I lined this up across top of carport and problem solved thanks

I bought three. They are
I bought three. They are compact and discreet and appear to work, the cats are no longer digging my bedding plants up. I like the fact that they flash a red light when they go off, telling you the battery is live, but I am waiting to see how long the battery lasts, as that they go off every time I walk by and are adjacent to a path in the back garden.

Very good for a little thing.
I was dubious if this was going to work but it does. I was swamped with cat mess in certain areas of the garden and resorted to laying mash so they couldn't dig but they just moved to another area. Installed this and can honestly say after a short while the two cats stopped visiting. I am very pleased, I would recommend this product due to the success I have had, I am thinking of buying another for my front garden. Thank you catfree.

The catfree was easy to set up and I have it attached to the mains via the catwatch adapter. Has kept the cats out from our our feeding area as cats were up the feeding tree and often around the feeding post waiting. The cats are NOT there now which is really good.
