Introduction
There is a widely touted anecdotal claim that Irish Spring soap has the ability to repel cats. The idea is that cats dislike the strong fragrance of Irish Spring and will avoid areas where it is present. This claim has led many cat owners to use bars or shavings of Irish Spring soap as a deterrent to keep cats away from certain locations, especially gardens, yards, and indoor furniture.
The origin of this claim appears to come from cat owners experimenting with natural repellents and noticing that some cats seem to dislike and avoid the scent of Irish Spring. The idea spread by word of mouth and internet forums as many people reported success using it to keep unwanted cats away. However, the evidence is still mostly anecdotal, and it’s unclear if the effect is universal among all cats.
History of the Claim
The claim that Irish Spring soap can repel cats first originated in the 1980s in the United States. It’s not clear who exactly started the claim, but it began spreading among cat owners as a home remedy to keep cats out of certain areas like gardens and furniture.
The idea gained popularity in the late 1980s and 1990s, likely due to the strong and distinctive scent of Irish Spring. As more people tried using the soap as a cat repellent and shared their experiences, the claim spread by word of mouth and eventually made its way onto the early internet on forums and blogs.
By the 2000s, the notion that Irish Spring repels cats became widespread and well-known, referenced in pop culture like cartoons and movies. Though not scientifically proven, many cat owners firmly believe in the power of Irish Spring soap to deter cats due to decades of anecdotal evidence.
Reasons for the Claim
There are a few main reasons why people claim that Irish Spring soap repels cats:
The most common reason is the strong scent of Irish Spring. As cited from https://www.catster.com/guides/does-irish-spring-soap-keep-cats-away/, cats have a much stronger sense of smell than humans, so the potent fragrance from the Irish Spring can be overpowering for cats. Cats generally do not like strong smells, so the scent is very off-putting for them.
Additionally, there is a lot of anecdotal evidence from cat owners who claim that placing bars of Irish Spring soap around their house or garden area keeps cats away. As explained in https://www.newlifeonahomestead.com/irish-spring-soap-repel-cats/, many people report that cats avoid any area where Irish Spring soap has been placed.
While not scientifically proven, these reports of Irish Spring effectively repelling cats has led to the widespread belief that it works as a cat deterrent.
Scientific Explanation
Cats have a far more powerful sense of smell than humans. A cat’s sense of smell is 14 times stronger due to having more olfactory cells than humans. This allows cats to detect odors at very low concentrations that humans cannot perceive. [1]
Experts state that while the strong scent of Irish Spring may deter cats initially, they can become used to the smell over time. The deterrent effect tends to diminish as cats acclimate. There is little scientific evidence that strong smells reliably repel cats in the long run.
Veterinarians advise using other humane methods to keep cats away from certain areas, like blocking access, distraction, remote deterrents, etc. Relying solely on strong scents is not considered an effective or ethical strategy.

Evidence For and Against
There are plenty of anecdotal experiences shared online of Irish Spring soap repelling cats. Many cat owners report placing bars of the soap around their property and seeing fewer cats enter those areas afterwards. For example, one cat owner said “I placed several bars of Irish Spring soap around the perimeter of my yard. It seems to be working great at keeping the neighborhood cats away” (source).
However, some cat owners find that Irish Spring does not deter their cats at all. As one owner reported, “I put Irish Spring soap around my flower beds to try to keep the neighbor’s cats from using them as a litter box. It didn’t phase my cat or the neighbor’s cats one bit” (source). So the effectiveness seems to vary from cat to cat.
There are currently no scientific studies investigating whether Irish Spring soap is an effective cat repellent. The evidence is limited to anecdotal reports, with mixed results. More research would need to be done to conclusively determine the effectiveness of Irish Spring as a cat deterrent.
Other Potential Cat Repellents
In addition to Irish Spring soap, there are some other commercial and household products that have been reported to help repel cats:
Commercial cat repellents often contain ingredients like pepper, citronella, eugenol, lemongrass oil, and garlic. According to WikiHow, these ingredients can trigger a cat’s sensitive sense of smell and urge them to avoid the area.1 Some popular commercial cat repellent brands include Sentry Stop That!, Nature’s Mace, and Coleus Canina.
For homemade options, some household items commonly recommended as cat repellents include:
- Citrus fruits – Cats dislike the smell of lemons, oranges, citrus peels, etc. A spray made of citrus juice or peels could deter cats.
- Vinegar – The strong scent of vinegar is unpleasant to cats. A vinegar and water solution can be sprayed.
- Cayenne pepper – Ground cayenne pepper sprinkled around plants, fences or other areas cats frequent may cause them to avoid the smell.
- Rosemary – This aromatic herb is said to be disliked by cats. Hanging bundles of dried rosemary could act as a repellent.
However, it’s important to note that homemade repellents are not guaranteed solutions, and results may vary depending on the individual cat.2 Proper use and reapplication over time may increase effectiveness.
Ethical Considerations
Before taking steps to repel cats, it’s important to consider the ethical implications. While cats can cause damage to yards and gardens, deterrent methods should be humane and not cause undue harm.
Certain repellents like ammonia, vinegar, coffee grounds, and tobacco carry risks if ingested by cats or other animals. Strong odors could also cause respiratory irritation. Rue and other scent-based repellents are generally considered safe, but should still be used judiciously.
Another ethical consideration is whether repelling stray cats simply relocates the problem instead of resolving it. Catch and release programs involving TNVR (trap-neuter-vaccinate-return) are a more humane long-term solution for stray cat populations. However, TNVR requires significant time and resources.
For homeowners needing a short-term cat deterrent, natural scents like citrus peels, garlic, and eucalyptus oil are likely the best balance between effectiveness and ethics. However, even natural repellents should be used sparingly and reapplied only as needed.
With any repellent, proper application instructions must be followed to avoid harmful side effects. Used responsibly, scent-based deterrents offer a moderate and ethical way to dissuade cats from yards or gardens.
Recommendations
When looking to keep cats out of your yard, it’s important to do so in a humane way that does not harm the animals. Here are some expert recommendations for repelling cats humanely:
The Humane Society recommends using motion-activated sprinklers or devices that emit high-frequency sounds, which can startle cats without harming them. Products like the CatStop use ultrasonic frequencies to deter cats.
As an alternative to cat repellents, the LawnLove experts suggest making your yard less appealing to cats by removing any outdoor food sources and ensuring fences are tall with smooth material so cats cannot climb them. You can also place chicken wire or lattice along the base of fences to prevent cats from entering.
Planting rue, lavender or pennyroyal may help repel cats with their strong scent. Citrus peels, coffee grounds or pipe tobacco can also be used as natural repellents. Be sure to reapply natural repellents frequently.
Whenever using any deterrents, check frequently to ensure they are not harming any animals. It’s best to combine multiple deterrents to effectively keep cats away humanely.
Conclusions
In summary, the evidence suggests that Irish Spring soap is not an effective cat repellent. While some anecdotal reports indicate it may deter cats, scientific testing has not confirmed this. The strong fragrance of Irish Spring likely puts off some cats initially, but there is no proof it repels cats over the long-term or prevents them from entering areas or gardens.
Cats have a much stronger sense of smell than humans, so strong fragrances can irritate them. However, cats can become accustomed to smells, so any effects of Irish Spring soap would likely wear off over time. Additionally, cats are intelligent creatures of habit that may continue accessing areas they are used to, despite unpleasant smells.
There are more effective commercial cat repellents available that use scents unpleasant to cats, like citrus or menthol smells. However, even these are not fully guaranteed to repel all cats in all situations. The best approach is to block access to any areas you want to keep cats out of with fencing or other physical barriers.
Overall, while Irish Spring soap may deter some cats temporarily in certain circumstances, it should not be relied upon as an effective, long-term cat repellent based on current evidence.
