We love catios because they provide your cat some safety while giving her outside time. Imagine having to stay inside all the time! Sun and fresh air improves her overall lifestyle.

The combination of the words cat and patio, (duh, you probably picked up on that by now) make up the cute word, catio.

Catios come in all different shapes, sizes, colors and and are fantastic for porches, windows, patios, yards, and even decks. Your feline bestie can gain access to his catio through a cat door that has been installed in the wall, window, or the door. Whether small or large, from basic to jaw-dropping luxurious, the appeal of catios for cats, is too hard to ignore.

Purrfectly Cozy Space: Introducing the Window Catio

Window catios are kind of like window boxes for cats! They are custom-built outdoor enclosures designed to fit over your window or patio door, allowing your cat to enjoy the outdoors from the safety of your home safely. They provide your feline friend with a safe and secure area to explore and enjoy the fresh air while protecting them from potential predators and other dangers. Window catios are a great way to give your cat the freedom to enjoy the outdoors in a safe and secure environment!

Are Window Catios Good For Cats?


Window catios can be very good for your cat! They are the perfect DIY small alternative to having a full catio. Cats in apartments now have a way to enjoy sunshine too. Cats have lots of fun watching from the comfort of a window sill, imagine how exciting it will be for them to do it outside, without a glass barrier.

Benefits of a window catio are:


It will protect your cat. The outdoors is full of danger. Vehicles and predators like coyotes, dogs, and raccoons can prove dangerous for your cat. There are other problems, like antifreeze from a car, pesticides from a local farm, exposure to parasites, your cat could get lost, and there’s also the possibility your precious kitty gets catnapped by the local shelter. A catio will allow your cat to enjoy the outdoors from a safe distance.

Reduced Vet Bills

Vet bills could be reduced. Vet bills are pricey. Outdoor cats can get into fights or suffer from other injuries that can dip into your pocketbook. There are also rabies and other diseases like FIV or Feline Immunodeficiency Virus to worry about. 

Protect Wildlife with a Window Catio

Outdoor cat enclosures reduce the population of free-roaming pets. These can give your cats their freedom and also reduce the chances of them wandering into unknown and possibly unfriendly territory. Neutering and spaying alongside catios can significantly reduce the number of cats roaming freely.

This can protect your cat, other pets and wildlife. Bird lovers will definitely appreciate your cat being safely enjoying fresh air and sunshine inside his enclosure. Birds and small wildlife like chipmunks will also be safer!

Multiple Cat Happy Home Life

Cat enclosures will reduce any issues you have with being an owner of multiple cats. Cats may be able to share their indoor space with other cats, but deep down, they are territorial by nature. They are also solitary hunters. A catio is a purrfect way to add new territory and reduce any feline conflict and bad behaviors in your household.

Outdoor Bonding Time

Enhance your human and feline bond with time spent outdoors. If your catio is large enough for a chair or bench, then having your cat enjoy the laziness and relaxing time outdoors next to their human is a fantastic way to build your bond with your cat. Plus, nature and fresh air make for some excellent quality time.

Window Catio Reduces Odors

You can reduce the number of indoor odors with an outdoor cat enclosure. A litter box inside the house can get a little funky. While its part of owning a cat, odor-producing waste rarely smells like roses. One way to cut down on this is by adding a litter box in the catio. It should never replace the indoor one because accidents can happen if you do get rid of it. Both will help alleviate a lot of the odor.

Friendlier Neighbor

Like a good neighbor, your cat will stay here. Some humans don’t like cats. This can include your neighbors. If your cat got out and used their new freshly planted flower bed as a litter box may cause some conflict. It can also cause problems if they have territorial cats of their own or strained the good neighbor relationship you have.

You will have peace of mind. A catio will significantly reduce the amount of worrying you do as your cat can be outdoors and stay safe. They will also get rid of any guilt you may have of keeping them indoors as it will help accommodate your feline friend’s desire to be out in nature. 

How much does a catio cost to build?

Depending on size and features, a custom-made catio can vary significantly in price. Prices can range from $2,000 to $20,000 or more. These catios are designed to fit your needs and include multiple levels, tunnels, shelves, and built-in cat trees. 

A catio kit is another less expensive option than a custom-made catio. These kits can still cost up to $5,000, but they come with all the necessary components for assembly, such as panels, doors, and hardware. A window catio can be an excellent option for those on a budget. These enclosures attach to a window and allow your cat to enjoy the outdoors while staying inside.

You can get pre-made corner pieces for your feline friend to take a cat nap or lounge gracefully in the sun. You can also use a sturdy ¾” exterior grade plywood.
