11 Ways On How To Keep Cats Out Of Window Sills

I’m often asked how to keep cats out of window sills. Cat owners want their furry friends to stay safe and not get injured or cause damage by jumping in the windowsill.

In this article, I’ll share 11 practical ways for keeping cats away from your precious window sills! Whether it’s blocking access with furniture, setting up deterrents like double-sided tape or citric juice, or providing alternative activities such as scratching posts and toys, there are plenty of strategies you can use to stop cats from using your window sills as play equipment.

Keep reading to learn more about all the options available so that you can help protect your fur babies while still allowing them to feel secure indoors!

Block Access To The Window Sill

It’s important to keep cats out of window sills for their safety, as well as the integrity of your home. Fortunately there are some steps you can take in order to block off access to the sill without harming or scaring your cat.

First, start by measuring the area around the windowsill and buy a plastic shield that is slightly larger than what was measured – this will ensure that it covers all potential points of entry.

Add A Cat Tree Near The Window

One way is by adding a cat tree near the window. This will give your furry friend something to climb and play with that’s closer than the windowsill itself. Plus, they’ll have an elevated view of their favorite parts of the house – which can be just as satisfying for them.

When placing the tree, make sure it’s not within arm’s reach of the window sill since this could encourage jumping onto it instead. Instead, opt for somewhere in the middle: close enough so your kitty can see outside but far enough away where they won’t consider hopping up on the actual sill.

To add more interest and incentive to stay off the sill, try including toys or treats at different levels of their new climbing spot so they become distracted from reaching for those hard-to-get places like high ledges or narrow counters.

Apply Citrus Scents To Deter Cats

It can be a real headache when cats decide to hang out on your window sill. But luckily, you don’t have to put up with it any longer! Citrus scents are an effective way of deterring curious cats from perching themselves in inconvenient places.

Here’s how:

  • Spray citrus essential oil around the window sill area – this will create a scent that is not pleasing for cats and they should learn to stay away after smelling it multiple times.
  • Place lemon peels or slices near the window sill, so long as you remember to replace them every few days since their smell won’t last very long.
  • Hang orange and lemon sachets filled with dried citrus peel or herbs like catnip – these fragrances will help keep cats at bay without being too overpowering for humans.

Overall, using citrus scents is an easy, simple and affordable way to prevent unwanted visitors from occupying your window sills. It takes time for cats to associate unpleasant smells with certain areas but once they do, they’ll soon recognize it as off limits!

Cover The Window Sill With Aluminum Foil

Having explored the use of citrus scents to deter cats from window sills, I now recommend another strategy for keeping cats away: covering the window sill with aluminum foil.

This reflective surface has been shown to be highly effective in discouraging cats from approaching surfaces they would normally climb onto or scratch. To achieve maximum success, create an uninterrupted layer of foil without leaving any gaps as cats may find these and attempt to slip through them.

What’s more, this is a very cost-effective solution that can easily be removed if desired. If you are looking for a long-term defense against cats accessing your window sills then aluminum foil could be the answer.

Not only will it prevent cats from climbing up but also discourage scratching on the glass which may otherwise cause damage over time. As such, by taking measures to cover your window sill with aluminium foil, you should be able to protect it effectively while still allowing light into your home.

Use Fragrant Herbs And Spices

I know how frustrating it can be to have cats frequenting window sills. It’s important to take immediate steps in order to keep cats away from these areas and protect both your home and kitty from any potential harm.

One effective way of doing this is by using fragrant herbs and spices. Scattering the scent of certain herbs and spices around the window sill will help deter cats from wanting to approach that area. Ideas for natural deterrents include lavender, rosemary, peppermint, citronella oil, or cayenne pepper mixed with water – just make sure that you’re not putting anything toxic near your furry friends!

A combination of these methods should help keep cats away from your window sills while also keeping them safe at the same time.

Use An Ultrasonic Pest Repeller

I understand how frustrating it can be to have cats trying to get into window sills. Here are some tips on how to keep cats away:

  1. Invest in an ultrasonic pest repeller. This device emits high-frequency sound waves that irritate animals, including cats, without humans being able to hear them.
  2. Make sure your window sill is not inviting for the cat by keeping plants or other items off of it since these may attract the curious feline.

The key here is prevention rather than punishment – after all, cats don’t understand scolding! With these tips you can effectively reduce the chances of finding yourself dealing with unwanted furry visitors in your window sills again.

Plant Cat-Repelling Plants

Having discussed using an ultrasonic pest repeller to keep cats out of window sills, let’s now explore another option: planting cat-repelling plants.

This is a great way to prevent cats from entering certain areas in your home without having to resort to any kind of physical or electronic barriers. There are several types of plants that have proven effective at deterring cats, such as lavender and rue. These fragrant flowers can be placed near the window sill where you want to discourage feline visitors.

It’s important to note that while these plants do work well for some cats, they may not be enough on their own if you’re dealing with particularly persistent felines.

I recommend trying this method before investing in expensive deterrent devices like motion sensors or sound alarms – chances are it will take care of your problem quickly and easily! Ultimately, whatever solution you choose should depend on how determined your cats are and what other options are available to you. With the right combination of strategies, keeping cats away from window sills doesn’t have to be a challenge anymore!

Place Double-Sided Tape On The Window Sill

One way to keep cats off window sills is by placing double-sided tape on the surface. This can create an unpleasant experience for them, as it will stick to their fur and feet. It’s important, however, not to use any type of adhesive that could cause harm or discomfort to your cat if ingested.

I suggest using a wide strip of tape that spans the entire length of the sill so that it creates a physical barrier between the window and your pet.

Set Up A Motion Sensor

Setting up a motion sensor is an effective way to keep cats out of window sills. It’s important to place the device in such a way that its range covers the entire sill, as well as any areas where cats may be able to access it from nearby surfaces.

I recommend using one with adjustable range and sensitivity settings so you can customize it for your cat’s individual behavior. These devices will usually emit sound and/or light whenever triggered by movement, which should act as enough of a deterrent to keep your cat away – but make sure the noise isn’t too loud or disruptive, especially if there are other pets in the home.

Be mindful of how close they’re placed to windows; while these sensors offer protection against curious cats, they also need adequate ventilation and shouldn’t be installed directly on glass or metal frames due to potential overheating issues. With proper placement and testing, this simple technique is an easy way to protect both your feline friends and your window sills!

Spread Pet Deterrent Sprays

One great way to keep cats off window sills is by using pet deterrent sprays. These products are designed to help discourage cats from exhibiting unwanted behaviors like scratching or climbing on furniture and window sills. They contain a harmless yet unpleasant scent that cats will recognize as an indicator they should stay away.

To use, simply spray the product directly onto surfaces where you don’t want your cat to go, such as the edges of your window sill. Re-apply every few days to ensure effectiveness.

Make sure to read the instructions carefully before applying any pet deterrent spray in order to get the best results possible. Additionally, it’s important not to rely solely on these products; instead, take time out of each day to engage with your cat and provide plenty of toys and activities for them so they won’t feel the need to climb up window sills in search of stimulation and entertainment.

Install Scat Mat

Moving on from pet deterrent sprays, another effective way to keep cats out of window sills is to install scat mats. These are specially designed rubber strips that provide a mild electrical shock when stepped on.

It’s important to understand the behaviour of the cat before deciding whether this option should be used – scat mats can cause anxiety in some cats which could actually make them more likely to go back onto the same spot they were shocked off of! However, when carefully introduced and monitored in an appropriate manner, these devices can be quite effective at teaching cats not to jump up onto surfaces they aren’t supposed to.

When installing a mat, it’s crucial that you place it somewhere where there isn’t much traffic or noise as this will only startle your pet further

Ultimately, if done correctly, scat mats can be an excellent way for keeping curious cats away from window sills and other restricted areas!


In conclusion, cats are naturally curious and love to explore their environment. Keeping them away from window sills can be a challenge, but with the right approach, it’s possible!

There are several methods you can use to deter your cat from climbing on window sills such as blocking access, adding a cat tree nearby, applying citrus scents or fragrant herbs and spices, placing double-sided tape, setting up motion sensors or spreading pet deterrent sprays.

You may also want to consider installing a Scat Mat for an extra layer of protection. With patience and proactive steps, I’m confident that you’ll soon have success in keeping your feline friends off of your window sills!
