Will Jeyes Fluid Deter Cats?

The good news is that Jeyes fluid works. In the majority of cases, cats (like humans) hate the smell of Jeyes fluid so it instantly puts them off. The moment you open a tin or bottle of Jeyes fluid, you’re hit in the face with the pungent odour. It’s not hard to understand why it works so well as a deterrent.

But don’t stop reading this article just yet, now that you know it works. There are actually several reasons why you may want to avoid using Jeyes fluid to deter cats.

How to Use Jeyes Fluid to Deter Cats

One of the most important things you must do is dilute the Jeyes fluid according to the instructions on the bottle. Neat Jeyes fluid is harmful to just about everyone and everything and you won’t want a dead cat on your conscience.

Once you’ve diluted it, grab some tea bags and submerge them in a bowl with your Jeyes fluid. We would highly recommend doing so with a pair of disposable gloves on to avoid causing damage to your own skin.

Once you have your Jeyes fluid soaked tea bags at the ready, you simply need to scatter them in your flower beds. If you find a cat tends to visit the same area or likes to dig up a particular pot then focus your teabag spreading efforts to these areas.

Should You Use Jeyes Fluid to Deter Cats?

You don’t need to be told that Jeyes fluid is far from natural. It’s full of chemicals and no chemical is particularly good, especially when ingested.

We know that Jeyes fluid has a high concentration of tar acids derived from coal tar oil alkaline. These substances are toxic if swallowed, if they come into contact with your skin, cause skin burns, eye damage, is toxic if inhaled, is toxic to aquatic life, is suspected of causing genetic defects and cancers… Hardly pleasant.

But it doesn’t end there – that’s just one of the chemical elements that make up Jeyes fluid.

You have to question whether or not harming aquatic life, other plants and even potential humans is worth the risk?

Will Jeyes Fluid Harm Cats?

As mentioned above, Jeyes fluid contains a chemical derived from coal acid which is particularly poisonous to cats. Additionally, cats are unable to flush their system of phenol. If they ingest Jeyes fluid (which contains phenol) they will be subjected to phenol poisoning.

We would always recommend erring on the side of caution when looking for deterrents – the last thing you want to do is cause harm to your neighbour’s cats and break the law, even if it is getting on your nerves! That’s why considering completely natural cat deterrents is the way to go when trying to stop cats pooping in your garden.


There are two sides to use Jeyes fluid. There’s the effectiveness side and then there’s the ethical side. In terms of effectiveness, Jeyes fluid is right up there with some of the most effective ways to repel cats from your garden. There’s no denying it works.

On the flip side, Jeyes fluid is loaded with chemicals. There’s a reason it smells so awful. Chemicals are unlikely to be good for cats so were they to inadvertently ingest any of the Jeyes fluid you’ve sprinkled you may cause harm to a cat. Not only that, but these chemicals will eventually seep into the local water table doing further harm to the wider wildlife in your area.

Yes, having a cat poop all over your perfect garden is infuriating, but is it worth killing over? Probably not. Especially when there are alternatives you can try which won’t cause harm.
