Cozy Cat Radiator Nook: A DIY Guide

DIY Radiator Cat Bed - Keep Your Feline Friend Cozy

As any cat lover knows, our feline companions have a penchant for two things: elevated perches and cozy warmth. If your cat is anything like mine, they are drawn to the radiator like a moth to a flame or perched atop the highest piece of furniture. This DIY radiator cat bed is the perfect solution to indulge your cat’s desires for both comfort and height.

This delightful project is excerpted from the upcoming book, DIY Projects for Cats & Dogs, a treasure trove of stylish and affordable DIY projects for pet owners.

DIY Projects for Cats & Dogs features 20 easy-to-build projects, ranging from a practical dog-friendly bike basket to an elegant rolling litter box cabinet. Each project is designed to be budget-friendly and simple to execute, making them accessible to DIYers of all skill levels. While the book is officially released on May 8th, you can secure your copy now by pre-ordering it from Amazon.

As a sneak peek of the chic creations featured in the book, let’s dive into my personal favorite: the DIY radiator cat bed.

Before we begin, please heed this important safety warning:

WARNING: This project is specifically designed for hot-water radiators found in homes heated by gas or oil, typically in older houses and apartment buildings. Electric radiators can pose a significant fire hazard if they come into contact with combustible materials. Therefore, this project is not suitable for use with electric radiators.

Materials You’ll Need for Your DIY Radiator Cat Bed

  • 1 sheet of OSB (oriented strand board), providing a sturdy base
  • 2 furring strips, approximately 2 feet (60 cm) each, to create the desired height
  • 2 shelf brackets, with a minimum of 8 inches (20 cm) on the shortest arm, for secure support
  • 4 corner braces, approximately 2-3 inches (5-7.5 cm), to reinforce joints
  • 2 nuts and bolts to fit the corner braces, ensuring secure attachment
  • Approximately 12 screws, for general assembly
  • Fabric, foam, and a staple gun, for creating a comfortable and aesthetically pleasing bed
  • Glue, for securing the foam to the board

Step-by-Step Guide: Building Your Cozy Cat Retreat

Step 1: Preparing the Furring Strips

Step 1: Cut Furring Strips for Radiator Cat Bed

Begin by cutting the furring strips to the appropriate length. The length you choose will determine the distance between the top of the radiator and the base of the cat bed. Refer to the image of the finished project for guidance.

Step 2: Attaching Corner Braces (Top)

Affix a corner brace to the top of each furring strip using screws. Ensure the braces are securely fastened for stability.

Step 3: Attaching Shelf Brackets (Bottom)

Step 3: Attach Shelf Brackets to Furring Strips

On the opposite side of the furring strip from the corner brace, attach a shelf bracket at the bottom of each strip. Use screws to secure the brackets firmly.

Step 4: Creating the Radiator Attachment

Step 4: Form U-Shape with Corner Braces

At the top of each furring strip, use a nut and bolt to connect a second corner brace to the first, creating a U-shape. This U-shape will fit snugly over the radiator, providing a secure connection.

Step 5: Securing the Board to the Brackets

Step 5: Attach Board to Shelf Brackets

Attach the OSB board to the shelf brackets using screws. Select screws that are short enough to avoid protruding through the top of the board. If any screws do slightly break through, cover the tips with adhesive putty for safety and aesthetics.

This step is significantly easier with a helping hand. Consider enlisting assistance to ensure proper alignment and stability.

Step 6: Adding the Foam Padding

Step 6: Glue Foam to the Board

Apply glue to the top of the OSB board and carefully position the foam padding. Trim the foam to size as needed, ensuring a smooth and even surface.

Step 7: Upholstering the Bed

Step 7: Staple Fabric to Underside of Board

Drape the fabric over the foam-padded board, ensuring it is taut and evenly distributed. Use a staple gun to secure the fabric to the underside of the board, pulling it gently to eliminate any wrinkles or slack. Trim away any excess fabric for a clean and professional finish.


The total cost of this project is approximately $12, excluding the cost of heating. However, the immeasurable joy and comfort provided to your feline companion is priceless. A warm and happy cat is well worth the effort!

Why Build a Radiator Cat Bed? Benefits and Considerations

Beyond the sheer joy of crafting something with your own hands, a DIY radiator cat bed offers several compelling benefits for both you and your feline friend. Let’s explore the advantages and some important considerations before embarking on this project.

Benefits for Your Cat:

  • Enhanced Comfort and Warmth: Cats are naturally drawn to warmth, and a radiator cat bed provides a cozy haven, especially during colder months. This can be particularly beneficial for older cats or those with arthritis.
  • Elevated Perch: Cats feel secure and stimulated when they have access to high vantage points. A radiator cat bed satisfies this instinct, allowing them to observe their surroundings from a comfortable perch.
  • Reduced Stress and Anxiety: A dedicated space that is warm, comfortable, and elevated can help reduce stress and anxiety in cats, promoting a sense of security and well-being.
  • Personalized Space: A DIY bed allows you to customize the size, shape, and materials to suit your cat’s preferences and your home’s decor.

Benefits for You:

  • Cost-Effective: Creating your own cat bed is significantly cheaper than purchasing a pre-made one, especially if you repurpose existing materials.
  • Creative Outlet: DIY projects offer a rewarding creative outlet and the satisfaction of making something functional and beautiful.
  • Customization: You have complete control over the design, materials, and size, ensuring that the bed perfectly complements your home and cat’s needs.
  • Bonding Experience: The process of building a cat bed can be a fun and engaging activity that strengthens your bond with your pet.

Important Considerations:

  • Radiator Type: As emphasized earlier, this project is specifically for hot-water radiators. Never use it with electric radiators due to the risk of fire.
  • Stability and Safety: Ensure that the bed is sturdy and securely attached to the radiator to prevent accidents. Use strong materials and secure fasteners.
  • Material Choice: Opt for non-toxic and pet-safe materials, especially for the fabric and foam. Avoid materials that could be easily ingested or pose a choking hazard.
  • Cat’s Size and Weight: Choose dimensions that are appropriate for your cat’s size and weight. The bed should be large enough for them to comfortably stretch out and move around.
  • Heat Exposure: Monitor the temperature of the radiator and ensure that the bed doesn’t become excessively hot, which could be uncomfortable or even harmful to your cat.
