The good news? You don’t need to spend a fortune!
With a few inexpensive materials and some creativity, you can build a cozy, weatherproof shelter to keep cats safe and comfortable.
In this article, we’ll explore 15 cheap and easy DIY outdoor cat shelter ideas that you can make with minimal effort.
What Makes a Good Outdoor Cat Shelters ?
Before diving into the DIY ideas, it’s important to know what makes a good outdoor cat shelter. According to Alley Cat Allies, an effective shelter should:
- Be insulated to keep cats warm in winter and cool in summer.
- Be waterproof to prevent rain or snow from soaking the inside.
- Have a small entrance to keep out predators.
- Be raised off the ground to avoid moisture and cold seeping in.
Now, let’s get started with some easy and budget-friendly ideas!
1. Storage Tote Shelter ($10-$20)
One of the simplest shelters you can make is from a plastic storage bin. This option is cheap, durable, and easy to assemble.
What You’ll Need:
- A large plastic storage bin with a lid
- A smaller Styrofoam cooler (optional, for extra insulation)
- Straw or fleece blankets for warmth
- A box cutter or utility knife
How to Make It:
- Cut a 6-inch round hole in one side of the tote (big enough for a cat but small enough to keep predators out).
- If using a Styrofoam cooler, place it inside the bin for added insulation.
- Fill the inside with straw (not hay!) or a fleece blanket. Avoid towels or regular fabric as they absorb moisture.
- Secure the lid and place the shelter in a quiet, hidden spot.
2. Insulated Styrofoam Box Shelter (Free or Under $10)
Some businesses, like grocery stores and pharmacies, throw away Styrofoam coolers that can be repurposed into cat shelters.
What You’ll Need:
- A Styrofoam cooler (ask your local pharmacy or grocery store)
- A box cutter
- Straw for insulation
- Duct tape
How to Make It:
- Cut an entrance hole in one side of the cooler.
- Line the inside with straw for warmth.
- Secure the lid using duct tape to keep it in place.
- Place the shelter in a covered area to extend its lifespan.
3. Wooden Crate Cat House ($15-$30)
If you have access to old wooden crates, you can easily turn them into sturdy outdoor shelters.
What You’ll Need:
- A wooden crate
- Plywood or a second crate for a roof
- Straw, blankets, or a heating pad
- Screws and a drill
How to Make It:
- Turn the crate on its side to create an enclosed space.

How to Make It:
- Cut an entrance hole in the box.

Pro tip: This shelter won’t last long in wet weather, so place it under a covered porch or inside a shed for extra protection.
5. Upcycled Cooler Shelter (Free or Cheap)
Got an old cooler lying around? It’s already insulated, making it a great shelter!
How to Make It:
- Remove the lid and cut a cat-sized entrance.
