Understand Why Cats Want to Go Outside
Cats have a natural instinct to want to go outside for various reasons. One key reason is their territorial nature. Cats are drawn to explore their surroundings and mark their territory, even if that territory extends beyond your home (source). Going outside allows them to patrol the area they consider their domain.
Cats also have a strong prey drive and desire to hunt. An indoor lifestyle lacks the stimulation of being able to chase birds, mice, and other prey. Given the opportunity, most cats will explore the great outdoors to satisfy their primal hunting instincts (source).
In addition, cats prone to separation anxiety may try to escape simply to reunite with their owner. Cats are social creatures that can become distressed when left alone for long periods.
Use Physical Barriers
One of the most effective ways to stop cats from going through windows is to install physical barriers like screens or mesh on the windows. According to https://www.rover.com/blog/cat-proof-window-screens/, cat-proof window screens made of steel or aluminum mesh with small holes can prevent cats from getting through. Look for screens with holes smaller than 1/4 inch so cats can’t get their claws caught in them. Products like the Fenestrelle Expandable Window Screen on Amazon are affordable and easy to install.
You can also block access to window sills by covering them with foil, double-sided tape, or plastic carpet protectors turned upside down. The slick surfaces deter cats from jumping up. Just make sure the window can still open and close properly.
For sliding glass doors, consider installing vertical blinds, high-tech electronic pet doors that only open for dogs, or plexiglass panels with a cat door installed at the bottom. These create a physical barrier while still allowing fresh air into the home.
Provide Inside Enrichment
One of the best ways to keep cats from climbing out windows is to enrich their indoor environment with activities and spaces that engage their natural behaviors. Place cat trees, perches, and beds near windows so they can look outside from a safe spot. Use puzzle feeders and interactive toys that challenge their problem solving skills and hunting instincts. Increase playtime and scheduled one-on-one interactions like brushing to burn off excess energy. According to resources from the Animal Humane Society and Atlantic Veterinary Hospital, environmental enrichment satisfies cats’ needs for adventure and leaves them more content to stay inside.
Specifically, set up tall cat trees and perches directly in front of or near windows so cats can look out safely from a high vantage point. Feed cats using puzzle toys that make them “hunt” for food. Try hiding treats around the house and switching up play routines to prevent boredom. Brush and play with cats daily to strengthen your bond. A stimulating home environment channels feline energy in positive ways and reduces motivation to escape.
Use Smells Cats Dislike
Cats have a strong sense of smell, and there are certain scents that they find unpleasant or alarming. You can use this to your advantage to discourage cats from jumping on windowsills or climbing through open windows.
Try placing strips of citrus peels, such as orange or lemon, along the windowsill. Cats dislike the strong citrusy smell. You can refresh the peels every few days as the scent fades. Alternatively, spray or wipe undiluted white vinegar directly onto the windowsill and window frames. The pungent odor of vinegar can repel cats.
As a temporary deterrent, use ammonia-based cleaners on surfaces around windows. Ammonia mimics the smell of cat urine, and the odor overwhelms a cat’s sensitive nose. However, never mix ammonia with bleach or other cleaners due to dangerous chemical reactions. Only use it occasionally and ensure proper ventilation.
Just be aware that cats can become accustomed to smells over time. Rotate different scent repellents and use them judiciously along with other training techniques. Check with your veterinarian before using any products on your cat.
Consider Pheromone Products
Pheromone products like Feliway diffusers or sprays contain synthetic cat pheromones that can help provide a sense of familiarity and comfort for cats. Feliway mimics the feline facial pheromone, which cats use to mark objects as safe and familiar. Diffusers steadily release pheromones into the air, while sprays can be applied directly to problem areas.
Studies on Feliway have shown mixed results. Some studies have found Feliway can help reduce stress and anxiety in cats, while others found no significant effects. It may work best alongside other methods. Place the diffuser near windows to encourage cats to stay inside.
Cat calming collars like Sentry or Comfort Zone also use pheromones. These can be worn on cats when they are in stressful situations. Some cats respond better to the collars than diffusers. Try them for at least a month to gauge effectiveness.
While not a cure-all solution, pheromone products are a gentle, drug-free option to try. They work best alongside environmental changes and rewards. Monitor your cat to see if these products seem to provide comfort and curb window climbing.
Use Remote Punishment
Motion detector compressed air spray devices can be an effective cat deterrent for windows. When the cat’s motion is detected, the device emits a quick blast of air to startle them. This remote punishment teaches the cat to avoid the area (source). Place the motion detector near windows, shelves, or other off-limit areas. Just be sure the cat has an alternative place to hang out.
You can also line windowsills with aluminum foil or upside down vinyl carpet runners. The foil creates an undesirable surface, while the carpet runners have uncomfortable nubs. Both make it unpleasant for cats to walk on. The foil crinkles loudly too when stepped on, startling cats away (source). This passive remote punishment helps deter cats without any effort on your part.
Try Double Paned Windows
Installing double paned windows can be an effective way to stop cats from climbing out windows. The airspace between the two panes of glass acts as an insulator, reducing outside noises and smells that may entice a cat to want to go outside (https://energy5.com/window-replacement-tips-for-pet-owners). Double paned windows have been shown to block 30% more outside noise compared to single pane windows.
With less ability to smell and hear the outside world, cats may be less motivated to try climbing out a double paned window. The two panes of glass also present more of a physical barrier compared to just a single pane. Research shows double paned windows are significantly more effective at reducing both noise and air transfer than single pane windows (https://glassdirectors.com/cat-flaps-in-double-glazing/).
If considering replacing current windows with double paned, make sure they are properly installed and sealed to maximize sound dampening. Also check that the window frames and any cat perches are securely installed. While more costly upfront, double paned windows can pay off long-term in energy savings and cat security.
Keep Litter Box Clean
Cats prefer a clean litter box and may start climbing out windows to relieve themselves if their litter box becomes too dirty. Here are some tips for keeping the litter box clean and enticing for your cat:
Scoop all waste out of the litter box daily. Allowing waste to accumulate will create odors that may deter your cat from using the box. Scoop morning and night to remove all solid waste.
Do a full litter change weekly. Once per week, dump out all of the litter and wash the box with soap and hot water to fully sanitize it. Let the box dry completely before refilling with fresh litter. This weekly deep clean will prevent bacteria growth.
Have enough litter boxes for your cat. The general recommendation is one more box than the number of cats in your home. Having multiple litter box options prevents crowding and gives your cat choices.
Use your cat’s preferred type of litter. Clumping clay litter is preferred by most cats. Avoid scented, crystalline, or lightweight litters if your cat does not take to them. Stick to the texture your cat likes best.[1]
Consider Catio Spaces
Enclosed outdoor areas for cats called “catios” allow cats to experience the outdoors safely. Catio spaces provide mental stimulation and exercise while preventing roaming, fighting with other cats, and other dangers of being outside freely. Catio enclosures attach to your home, protect your cat from cars, predators, and more while letting them enjoy fresh air and sunshine.
There are many options for catios. You can purchase pre-built catio kits or custom designed enclosures, or build your own using DIY plans. According to Catio Spaces, catio kits generally range from $350 – $600. Building your own can be more affordable but requires tools and construction skills. The size and features like ramps, scratching posts, and shelving impact the cost. Consider your budget and abilities when deciding between DIY or purchasing a catio.
Providing a catio space lets cats experience outdoor enrichment safely. It may satisfy their desire to be outside so they’re less inclined to dart out doors and windows.
When to Seek Professional Help
In most cases, persistent climbing behavior can be curbed with consistent training and providing proper enrichment. However, if your cat continues exhibiting excessive anxiety, damage, or ignoring deterrents, it may be time to seek professional advice.
According to ClassActCats, you may want to contact an animal behavior professional if your cat is putting himself or others in danger from the climbing and escape attempts. Persistent meowing and signs of separation anxiety are also good reasons to seek outside help.
The experts at The Wildest recommend considering a cat behaviorist if your feline friend isn’t responding to any of your solutions for the climbing and escape behavior. They can assess your cat’s unique personality and situation to develop an effective plan.
Seeking help sooner rather than later can prevent damage to your home as well as stress to you and your cat. Consult your vet for a referral or contact a certified applied animal behaviorist. With some extra guidance, you can get your cat’s climbing under control.
