the Cactus Cat Intruder Deterrent Repellent Wall Fence Spikes: Pack of 10 (4.5M to 13.5M) - BROWN

Put these up to stop my Cat from jumping up on the fence then straight over on to the roof of the car on the driveway. It’s been like a superhighway for mine and my neighbours cats. You will never stop a cat 100% cos we all know how agile and resourceful they are but these have cut down that activity by probably 85% and you can see how uncomfortable and not worth the effort they’ve found it when they do bother. Super easy to install but don’t skimp out on using a screw in all the holes because they will rise up and bend in the heat. With the correct amount of screws used it’s all as it should be. (2 packs used in the picture and that’s also covered 1 fence length additionally you can’t see in the picture).

Brilliant stopped the cats straight away

These spikes are much tougher and sharper than they look, so in that respect they are excellent. They are also easy to install - just find a few screws and screw them in. But if you are installing these on a hot sunny day, I have a tip for you. Make sure you leave them out in the sun for half an hour or so, BEFORE you install them, to allow them to expand first. If you don't, they will warp somewhat in the sunshine. I have attached two photos for you to see 1) Installed without warming up first 2) Installed AFTER allowing for expansion. They also work best on fences that have a flat top surface. Fences that are shaped into a peak (a triangular point) are more difficult, as the middle screws cannot easily find a middle point. Overall though, I like the look of them - they are well packaged and well made. They also came with a small warning laminate, which I'm told you are advised to put up - if you don't, then a burglar has the right to take you to court if they injure themselves, because they were not 'warned' about the spikes. Ridiculous, and indeed a thick blanket would probably be enough for a burglar to make these somewhat redundant, but they would have to come prepared, and may still slow them up a bit, and any deterrent is good in my book, so overall, a decent addition to your security measures when it come to deterring the more opportunist house-breaker. Probably worth mentioning to your neighbour though before you install them - if your neighbour got injured somehow, they could also sue you. And if your fence faces a public highway, that could also be a legal mind-field. That all said, I like them!

Very good product. Easy to install. The points are sharp and the strips are easy to cut to the right size.

Brilliant item

Doesn’t really do the job

Some reviewers seem to be having problems with birds and cats still using their boundary walls and fences. I can only assume that these are wide-ish walls or fences with broad rails along the tops. In our case the fences are narrow at the top and these do a fabulous job of keeping pigeons and cats away. I can tell cats don't like them because they began looking for other places to get in. The trick then is to shoo them away and watch where they go over the fence - put down some more and eventually they don't come back.It's often better not to allow cats to get up the fence easily. If they have to jump up and grab the rail to haul themselves up, they will not like those spikes having their weight on them. If they can sidle over onto the fence it will hurt a lot less and they can pick their footing. It's always a good idea to compel them to have to put their weight on the spikes. They'll quickly realise that the gain isn't worth the pain.I don't dislike cats, but I like being able to walk on our new gravelled areas without fear of nasty little surprises.They're not as nice-looking as a clean fence top rail, but they are about as unobtrusive as any of these solutions can be.Addendum: We've had these up while now and I have a couple more observations to make. The first is that most of the smaller birds take a while to get used to these but eventually figure out how to use the fence top as a perch by standing between the spikes. It keeps larger birds away, but sparrow-sized birds get along with the spike strips.The other observation is that I installed these in coldish weather (autumn and spring), and I've noticed that in hot weather they will tend to buckle upward against the screws as they expand quite a bit in the heat. If I'd known this I would have installed them on hotter days so that they'd look okay in the heat but be even tighter against the top rail when the weather got colder and they would shrink and tighten against the screws instead. Of course they can be refixed on a hotter day. They still do a good job of keeping unwelcome pests at bay.

Pleased with purchase, would recommend.
