Looking after it

Fence tops sit under whatever is growing over them, so this run fills with leaf litter faster than a wall ledge does. Clear it annually and trim back what is dropping onto it.

About this product

A fence top is a cat's road, not its destination.

Blunt moulded strips for the top of a fence, a wall or a gate. They make the route uncomfortable enough to be worth avoiding, and they cannot injure.

Cats use a fence line as a route between places, which is why a partly treated fence gets you a detour rather than a result.

The strip is one piece of injection moulded plastic, 500 mm long, with blunt points that make a surface unpleasant to stand on without being able to injure.

It fixes along a timber rail with screws, or to a block capping or a gate top with an exterior adhesive.

Work out where the cats get UP as well as where they walk. Two or three access points are often the whole job.

Measure the run, divide by 50 cm and round up, and remember the post tops.

The honest framing for this product is that it changes a cat's mind, not its physiology. A cat that has been walking your fence for a year has a habit and a reason, and the strip removes the comfortable surface it was using. Most cats simply take another route within a night or two.

It is also worth saying that a boundary fence usually belongs to two households. Fixing something to a shared fence is a conversation before it is a purchase, and blunt cat spikes are far easier to have that conversation about than anything that could injure an animal.

If the cats are coming into a garden rather than walking a fence, spikes are only part of it. They close the fence route; they do nothing about a gap under a gate or a low wall at the front. Look at the whole boundary before deciding how many strips to order.

The choice between this and the stainless strip is mostly about site rather than quality. Moulded plastic is a single piece with nothing to assemble, it costs less per metre and it sits lower, which matters when the run is at eye level. Stainless is the one to pick for coastal exposure, for anything a heavy animal will lean on, and for anything that has to be specified.

Fixing decides how long it stays put far more than the material does. On timber, screws. On a block capping or a painted surface, a UV stabilised exterior adhesive on a surface you have actually cleaned. Grit and old growth under an adhesive strip is why it lifts in a year.

None of these strips is a trap and none of them is sharp enough to injure. They work by making a surface unpleasant to stand on, which is also why placement beats quantity: a treated rail with an untreated post beside it is a step, not a barrier.

Still deciding?

Not sure yet? That is fine.

You can change your mind. We give you 14 days from delivery on any unused item. That is our own policy rather than a New Zealand statutory right, because there is no statutory cooling-off period for an online purchase here, and we would rather say so than imply a right you do not have. Send it back unused and in resaleable condition and we refund what you paid for it; on a change of mind you cover the return postage.

If it turns up faulty, damaged or not as described, that is on us. The Consumer Guarantees Act 1993 gives you a repair, a replacement or your money back, we pay the return postage, and nothing on this page limits that. Read the detail on our refunds and returns page, or ask us anything before you order.

Frequently Asked Questions

Will these hurt a cat?

No. The points are blunt. A cat finds the surface unpleasant to stand on and takes a different route.

Is it legal to fit them?

Yes. A blunt deterrent that makes a surface uncomfortable is lawful. Anything designed to injure an animal is not, and this is not that.

Do I need my neighbour's permission?

On a shared boundary fence it is the sensible first step, and your fence agreement may require it. It is visible from their side too.

How much of the fence do I need to do?

As much as the cats can walk, or the two or three points where they get up. One treated panel is a detour.

Where do cats usually get up?

A bin, a woodpile, a low shed roof, a compost bay, a branch, a wheelie bin left against the fence. Move those before you buy anything.

How long before they stop?

Usually a night or two. A cat with a strong habit may test it a few times.

Will they work on a wire fence?

No. There is nothing flat to fix to. They need a rail, a capping or a post top.

What about the posts?

Cut short pieces and do them. A bare post top is a standing spot and people always forget them.

Can I fix them to a gate?

On the top rail, yes. Keep them clear of where a hand goes when you open it.

What fixings on a timber rail?

Screws, and stainless ones if you would rather not have rust streaks down the fence.

What about a block wall capping?

An exterior adhesive is simpler than drilling. Clean and dry the capping first.

Will they stop possums too?

They discourage them. A possum is heavier and more determined, so screws rather than tape, and consider the stainless strip on a serious run.

Will they stop birds?

On the rail, yes, in the same way.

Are they obvious?

At fence top height they are at eye level, so more visible than on a roof. Black on a dark fence is the least obvious combination.

Can I paint them?

Yes, with an exterior paint suited to plastic, and people often colour match them to the fence.

Do they go brittle?

They are made for outdoor use and shrug off ordinary temperature swings.

Can I cut them?

Yes, with a hacksaw or sturdy snips.

How many per metre?

Two, and round up.

Will they deal with cats already in the garden?

No. They close the fence route. A cat coming under a gate needs the gate dealt with.

What if it is my own cat?

Then think about where you would rather it went, because it will find another way and you may prefer the one it was using.

Do they work in the rain?

They are a physical barrier, so weather makes no difference.

Are they safe if a child touches them?

They are blunt, so a hand on them is uncomfortable rather than harmful. On a low fence in a garden with children, that is worth thinking about anyway.

Can I use them on a deck rail?

You can, but a deck rail is somewhere people put their hands. We would think twice.

Do they need maintenance?

Pull the leaf litter out once a year, especially under trees.

Can I remove them later?

Screwed, easily. Adhesive will need cutting off.

Do you sell for a long boundary?

Yes. Send the metres through the wholesale page.

Do you install them?

No, we supply only. A fence line is a straightforward DIY job.

How much is delivery?

Free on orders over $75. Below that the only method offered is Express Delivery at $25, and there is no minimum order.

Can I return it if I ordered too many?

Yes. We give you 14 days from delivery to change your mind on any unused item. That is our own policy rather than a New Zealand statutory right, and your Consumer Guarantees Act rights are unaffected.

The complete guide

A humane fence topper, and the etiquette that comes with it

4 min read Bird Spikes Company

What this actually does

A cat walking a fence is following a route between two places it wants to be. The strip does not hurt it and is not designed to: the points are blunt, and what happens is that the surface becomes unpleasant to stand on and the cat picks a different way round.

Most cats change their route within a night or two.

Treat the route, not the fence

The mistake is to treat the panel where you see the cat. Look instead at where it gets up: a wheelie bin, a woodpile, a low shed roof, a compost bay, a branch. Move the bin and you may not need the spikes at all.

Then treat the pinch points on the route, including the post tops, which everyone forgets and which are a favourite standing spot.

The neighbour conversation

Boundary fences usually belong to two households, and your fence agreement may require agreement before anything is fixed to one. It is also visible from their side, at their eye level.

Blunt cat spikes are an easy conversation to have because there is nothing to argue about: they cannot injure an animal. That is worth leading with.

Fixing

Screws in timber, stainless ones if you would rather not have rust streaks. Exterior adhesive on block capping. On gates, keep the run clear of where a hand goes.

Where we would think twice

A deck rail is somewhere people put their hands. A low fence in a garden with small children is somewhere hands and faces end up. The strip is blunt and contact is uncomfortable rather than harmful, but placement is still worth thinking about.

What it will not fix

It closes the fence route. A cat coming under a gate, over a low front wall or through a hedge is unaffected, so walk the whole boundary before deciding how many strips to buy.

And if it is your own cat, it will find another way in. You may prefer the way it was using.
