7 Cat Window Box Ideas for Indoor Outdoor Enrichment

Cat Window Boxes

As conscientious cat owners we are often worrying about our pets. If they’re indoor cats we worry that they’re not entertained or stimulated enough, and if they’re outdoor cats we worry about them getting lost, catching mice or having to cross busy roads. So, what’s the solution? 

A cat window box is a great way for cats to get the best of both worlds, and one of the easiest and most versatile cat enclosures to install.

What is a Cat Window Box?

A cat window box is an enclosure that is attached to the window frame, or the outside of your home. When you open the window, your cat can access this space for some outdoor time, sunshine, bird watching, etc. You can also put in a cat flap so the window can remain open and your pet can climb through at their leisure.

You can get different types of cat window boxes such as:

  • Plexiglass cat window boxes made from acrylic
  • Bubble cat window boxes, also a plexi acrylic material
  • Cat Solarium window boxes
  • Window mounted cat litter boxes
  • Glass cat window boxes
  • Screen window boxes
  • or build your own with timber, wire, pvc pipe, or recycled materials from around your home

Some cat window boxes are used as a way of letting your cat be outside with the wind in their fur, and others are designed to give your cat a bit of space where they can observe everything that’s going on around them.

Some are large and look like an extra kitty balcony and some are more the size of aircon units. Whichever you choose, the aim is the same – to get your cats interacting with their surroundings.

Why Should I Get a Cat Window Box?

Because they’re a great way of entertaining your cat in a fun and safe way. They can be surrounded by birds cheeping, watch the comings and goings on the street and have their own part of the house. 

A bit of outside exposure can also help keep any unwanted behavior at bay. If not stimulated enough, indoor cats can become destructive and frustrated. Having somewhere else to go, especially if it’s open with a few of their favorite toys, will keep them entertained so they’re less likely to scratch the furniture or pester you on a work call. 

How to Build a Cat Window Box

This video shows you how to build a cat window box using plywood, pre-made window screens, nails, screws, and some wood glue. It’s simple, and for those of you who aren’t super handy, it’s easy to construct.

This cat window box isn’t fixed to anything, making it ideal for renters, or those who want to move it to different windows around their home. It sits inside a double hung window frame, the bottom of the window resting on the top of the box. Take a look below:

This DIY window cat box is simple, made by Cat Toy Lady. She refers to it as a cat balcony. She uses a staple gun in ways I have not seen before, but it makes for a budget friendly item that also isn’t fixed to your home. Using dollar store items, some simple pine timber, plywood, and spray paint, it also includes a cat flap as a door.

It takes a more planning than the video above, as it is made to fit your exact window dimensions. If you watch to the end of the video, she shows you how she measures her window frame to fit the cat box, which also helps to secure it in place so it won’t fall out.

It is worth mentioning that both of these windows are hung windows that lift upwards. If you have a horizontal sliding window, you might want to consider something like the Patio Pacific cat door for horizontal windows. You can choose from four different window heights.

I also found this fence window when browsing Amazon. It would be perfect for a bubble window box. Made from acrylic, it measures 12.4 x 4.7 inches. You could easily mount this onto a piece of plywood cut to fit inside your window frame. Add a ledge for your kitty to perch on and stare out through the bubble at the world outside.

Also check out this video below by DIY Xplorer, where he builds a 12ft long outdoor cat window box that fits between two windows. He also installs it onto a brick wall, so for those of you with brick homes, this is a good video to watch. This pocket hole jig is on my must buy list after watching how easy it looks in the video!

One thing to note is the cost was around $300 and it took about 2 weeks to build, part time. They used pet safe mesh to screen in the cat enclosure, but it has been scratched already and damaged by the cats. Using a woven wire mesh will be more durable.

If you prefer to buy an outside cat window box, take a look at this one below from Habitat Haven:
