Outdoor cats often wander onto neighboring properties to explore, hunt, or find mates. While this natural feline behavior can frustrate property owners trying to keep cats away, using dangerous deterrents like fence spikes is inhumane and ineffective. This article examines whether fence spikes actually stop cats from entering yards and gardens, the welfare risks they pose to cats and other animals, and more humane alternatives for discouraging trespassing.
What Are Fence Spikes?
Fence spikes, also known as security fence spikes or anti-climb fence spikes, are metal spikes installed along the top of fences, walls, or other barriers (Source). They are designed to prevent intruders from climbing over by making it difficult and dangerous to grip the top of the fence. The spikes are angled outwards, facing potential climbers.
The spikes are typically made of steel or wrought iron and can range from simple single point spikes to more elaborate scrolled or rotating spikes. They are available in various sizes and shapes to suit different fence types and security needs (Source).
Fence spikes can be built into a fence during manufacturing or retrofitted to an existing fence. They may be attached by welding, bolting, or clamping them to the fence frame or posts (Source). Proper installation is important to ensure the spikes are securely fixed and angled outwards at an effective deterrent angle.
Intended Purpose of Fence Spikes
Fence spikes are primarily intended to deter climbing and trespassing. They originated as a security measure to prevent intruders from scaling walls and fences around commercial and residential properties.
The sharp protruding spikes provide an immediate visual deterrent, warning potential trespassers of the dangers and difficulties involved with attempting to climb over a spiked surface. This approach aims to stop intruders before they even attempt to breach a secured perimeter.
While more benign barriers may physically obstruct climbing, fence spikes take an aggressive approach by threatening bodily harm. Their purpose is to intimidate and scare off human intruders seeking unauthorized entry.
Do Fence Spikes Stop Cats?
There is evidence both for and against the effectiveness of fence spikes in deterring cats:
Fence spikes can deter some cats by making it uncomfortable for them to climb or walk on top of a fence. The sharp metal spikes create an unpleasant surface that cats will avoid if possible. Some sources note fence spikes have proven effective against certain cats as a deterrent (https://oscillotamerica.com/blogs/news/all-your-questions-about-cat-proof-fencing-answered-part-2).
However, other sources argue that many cats are still capable of jumping over or carefully maneuvering around fence spikes. Cats have sharp claws that allow them to grip surfaces and avoid putting pressure on the spikes. Additionally, curious and determined cats may still attempt climbing a spiked fence, risking injury in the process (https://www.insight-security.com/fence-spikes).
So while fence spikes can deter some cats, they are not guaranteed to stop all cats. Cats that are highly motivated to access a yard may still find ways over or around spiked fencing.
Humaneness Concerns
There are some concerns among animal welfare groups and cat owners about the humaneness of using fence spikes to deter cats:
Fence spikes could potentially cause injuries to cats if they attempt to climb or walk on them.
While the spikes are often blunted for plastic or rubber versions, the discomfort and instability underfoot could still lead to falls or scrapes (https://www.purrfectfence.com/blogs/news/do-cat-spikes-work-what-alternatives-are-available).
Some animal welfare organizations like the RSPCA have spoken out against the use of cat spikes, deeming them an “unacceptable way of restricting cat’s access” as they cause distress and discomfort when cats come in contact with them (https://www.rspca.org.uk/adviceandwelfare/pets/cats/guide). Groups like the ASPCA also recommend alternatives that are less invasive to discourage cats.
There are concerns that cat spikes do little to actually teach cats to avoid an area, and may not provide a long-term humane solution. Cats may continue trying to access the area and risk injury.
Some cat owners feel the spikes are cruel and overly punitive, especially when a cat’s access to its own home garden is being restricted.
Therefore, many argue gentler deterrents or training methods should be attempted before resorting to solutions like cat spikes that risk causing harm.
Alternatives to Fence Spikes
Fortunately, there are a number of humane alternatives to using fence spikes to deter cats from entering an area. These more compassionate options protect both cats and other animals while still accomplishing the goal:
Physical barriers like fences, walls, and thick plantings can block cats without harming them. Short fences around planter boxes allow access for shorter wildlife while keeping cats out. Wrap tree trunks in flexible plastic or metal to prevent climbing. Cover areas with chicken wire, lattice, or special netting with openings too small for cats.
Motion activated sprinklers, ultrasonic devices, and scat mats use startling sounds, lights or harmless shocks to condition cats to avoid an area. Citrus or fragrance repellents use scents cats dislike to deter them. Applying mulches that are spiky but don’t penetrate skin can make areas uncomfortable for cats to dig without injuring them.
Preventative measures like keeping cats indoors, supervising time outdoors, spaying/neutering, and identification can reduce unwanted cat traffic more humanely as well. Enticing cats to “approved” areas with catios, scratching posts and catnip may also help redirect scratching or climbing away from off-limits areas.
With some creativity and patience, there are many effective and humane options to try before resorting to harmful anti-cat spikes.
Legality of Fence Spikes
The legality of using fence spikes is dependent on local regulations. Many municipalities prohibit or restrict the use of sharp spikes and barbed wire for safety and liability reasons. For example, according to Roller Barrier, “In the USA homeowners associations and municipal laws generally prohibit the use of sharp fence spikes” (source).
Before installing fence spikes, it’s important to check your local building codes and homeowner association rules. The Fencepedia recommends, “The best way to be completely sure if fence spikes are legal in your area is to speak to the local building department of your municipality or city. Decisions on the legality of anti-climb spikes on top of fences are made at this local level” (source). Installation without proper approval can result in fines or being forced to remove the spikes.
In summary, fence spike regulations can vary greatly depending on the local jurisdiction. Checking in advance and getting necessary approvals is crucial, as spikes are prohibited in many areas due to safety concerns and liability should injury occur.
Case Studies
There are a few examples where fence spikes have been used effectively to deter unwanted climbing and trespassing. According to a case study from Roller Barrier, fence spikes installed around a multi-use games area (MUGA) pitch successfully prevented unauthorized access and vandalism. The spikes acted as an effective physical deterrent without causing injury.
However, there have also been some controversies surrounding the use of fence spikes. As noted in a study published in the Journal of Forensic and Legal medicine, fence spikes have been associated with accidental deaths in some cases. The study described two incidents where individuals were impaled on the sharp ends of fence posts and died from their injuries (Heath, 2018). This highlights concerns around the potential risks of fence spikes to human health and safety if used improperly.
Overall, while fence spikes can physically deter climbing and trespassing if installed correctly, they also carry risks of injury or death if handled carelessly. Proper precautions, signage and mounting at safe heights is important for ethical and legal use.
Conclusions
When reviewing the effectiveness of fence spikes for deterring cats, the research indicates mixed results. Some studies have found that fence spikes can deter cats from 50-60% of the time when properly installed along the tops of fences and other surfaces [1]. However, other research suggests that motivated cats will still likely cross over spikes, especially if they are determined to reach something on the other side like food or other animals [2]. Much depends on the individual cat’s personality and motivation.
In summary, the evidence indicates fence spikes may deter some cats some of the time, but they are far from 100% effective. Spikes should be seen as one potential element in an integrated deterrent strategy rather than a standalone solution. They may work best when combined with other humane deterrents tailored to the specific cat.
