Summer Cooling DIY Cat Bed for Hot Apartments

By Sebastian Frank, Founder of CozeCats · Last updated: October 28, 2026

Most cat bed tutorials are about warmth: fleece donuts, plush caves, heated pads. That's the opposite of what a cat needs in a top-floor apartment in July. This guide is about a DIY cat bed built to keep a cat cool, with three builds you can make in an afternoon, plus where to put them and how to tell when your cat is too hot.

A quick word on where this comes from: at CozeCats we design and manufacture furniture for cat homes, and how materials hold or release heat is part of choosing them. Fabric, wood, stone and mesh (see our guide to cat furniture materials and finishes) behave very differently when a warm cat lies on them for hours, and that difference is what these builds rely on.

How a cooling DIY cat bed works

Cats don't sweat much. They lose a little heat through their paw pads and by panting, but mostly they cool down by lying on something cooler than they are. That's why you find your cat stretched flat on bathroom tiles or the kitchen floor in summer. PetMD's article on whether to shave a cat for summer lists "spending more time in contact with the floor" as a sign of heat stress, along with panting and drinking more.

A cooling bed uses one of three tricks:

• Airflow: a raised mesh bed lets air move under the cat, so heat doesn't build up underneath.
• Thermal mass: ceramic tile or stone feels cool because it pulls heat away from the body and holds a lot of it before warming up.
• Active cooling: a frozen water bottle, wrapped well, gives a cool zone for a few hours.

The best setup offers two of these side by side, so your cat can choose. Cats regulate their own temperature well when they have options, and a bed they can't leave is a bed they won't use.

Materials and cost table

Pick matte or unglazed tile so paws don't slip, and choose untreated pine. Skip pressure-treated lumber and strong-smelling stains anywhere a cat sleeps.

Build 1: raised mesh cot (best for airflow)

This is a small version of the elevated dog cot, scaled for a cat. It's the best of the three for humid apartments, because nothing under the cat traps heat or moisture.

1. Cut the frame. Cut two 1x2 boards to 20 inches and two to 16 inches. Sand all edges smooth.
2. Join the corners. Glue and screw the boards into a rectangle with 1.25-inch screws, pre-drilling to avoid splitting. Check it sits flat.
3. Add legs. Screw a 3-inch block of 2x2 under each corner, then put a rubber foot on each so the cot doesn't slide on hard floors.
4. Stretch the mesh. Wrap breathable mesh or plain cotton canvas over the frame and staple it underneath every 2 inches. Pull it tight as you go, working from the center of each side out to the corners. It should sag about half an inch when you press the middle.
5. Cover the staples. Glue a strip of felt over the staple line underneath so no staple heads are exposed.

Test it by pressing hard on the middle with your hand. If the mesh pulls loose, add more staples. A 3-inch height is enough for air to move underneath while staying easy for older cats to step onto.

Build 2: ceramic tile bed (best for a quick cool spot)

A tile bed is a frame that holds a ceramic tile, so the cool surface stays put and is easy to clean.

1. Size the frame. Cut scrap wood strips (about 3/4 inch thick) to make a frame that fits around your tile with 1/8 inch of space. A 16x16 tile suits most adult cats.
2. Build the base. Glue the frame onto a piece of thin plywood the same size. Let it dry.
3. Add a cork layer. Lay a cork sheet inside the frame. It stops the tile from rocking and protects your floor.
4. Set the tile. Drop the tile in. Don't glue it, so you can take it out to wash.
5. Finish. Sand the frame edges round and stick felt pads underneath.

Tile works best in rooms that stay at least a little cool, because it slowly warms up to room temperature. In a very hot room, keep it out of direct sun, or swap in a second tile that's been in a cooler spot. Don't put tiles in the freezer, since a very cold surface can be uncomfortable and slippery from condensation.

Build 3: frozen-bottle cool pad (best for heat waves)

This is the fastest build and the most useful on the worst days.

1. Fill two 16 oz plastic bottles about 80% full with water and freeze them. Leave room for the ice to expand.
2. Wrap each frozen bottle in a thick cotton towel, rolled at least twice around.
3. Lay the wrapped bottles side by side inside a cotton pillowcase or tea towel folded into a pad.
4. Put the pad on one half of your cat's usual bed or the mesh cot, leaving the other half at room temperature.

Swap the bottles every three to four hours, and dry the towel between uses so it doesn't get damp. Never put ice or a bare frozen bottle against your cat. Avoid gel ice packs that a cat could chew open, because some contain chemicals that are harmful if swallowed.

Make a breathable cover for any DIY cat bed

Fabric choice matters as much as the build. Fleece, plush and memory foam all hold heat. Linen and cotton don't. Cut a sleeve from an old linen shirt or cotton sheet, sew it into a simple pillowcase shape, and slip it over the cot or a thin cushion. Wash it weekly, since summer means more shedding.

If your cat already has a favorite fleece bed, don't throw it out. Swap its cover for cotton for the summer, or move it to a cooler room and add a cooling option next to it.

Where to put a cooling bed in a hot apartment

A great cooling bed in the wrong spot won't help. In apartments, especially top floors and west-facing units, placement often matters more than materials.

• Go low. Warm air rises. The floor is the coolest level of the room, so keep summer beds on the ground, not on high shelves or cat trees.
• Avoid sun. Keep beds out of direct afternoon sun and away from south- or west-facing windows. Close blinds during the hottest hours.
• Use bathrooms and hallways. Interior spaces with tile floors and no windows are usually the coolest spots in an apartment.
• Use airflow carefully. A fan moving air across the room helps, but don't point it directly at the bed all day.
• Put water nearby. Place a full water bowl within a few steps of each cooling spot, plus at least one more somewhere else.

Which cats need a cooling bed most

Every cat can overheat, but some need more help. These include flat-faced breeds like Persians and Exotic Shorthairs, who can't pant as well; long-haired cats such as Maine Coons and Ragdolls; overweight cats; seniors; and cats with heart or breathing problems. If your cat is in one of these groups, set up two cooling options before the first heat wave, not during it.

Heat safety: signs your cat is too hot

A cooling bed helps on hot days, but it can't fix a dangerously hot room. Know the warning signs. PetMD's guide to heatstroke in cats lists panting, red gums, vomiting, disorientation and collapse as signs of an emergency. Open-mouth breathing in a cat is never normal and always worth taking seriously.

• Mild heat stress: more lying on hard floors, less energy, drinking more, grooming more. Move your cat to a cooler room and offer the cool pad.
• Emergency: panting, drooling, bright red gums, wobbly walking, vomiting. Move your cat somewhere cool, put cool (not ice-cold) damp towels on their paws and ears, and call your vet or emergency clinic right away.

The ASPCA's hot weather safety tips are worth reading before summer too. If your apartment has no air conditioning, plan where your cat will go during a power cut or heat wave.

Cleaning and upkeep

Summer beds get dirty faster. Wash cotton covers weekly. Wipe tiles with warm water and mild dish soap, rinse well, and dry. Avoid essential-oil or pine cleaners, which can be harmful to cats. Check the mesh cot monthly for loose staples or frayed mesh, and re-tighten as needed. When temperatures drop, store the cot and tile and bring back the warm beds. Your cat will tell you when it's time.

FAQ

What is the best material for a cooling DIY cat bed?

Breathable mesh, linen and cotton for airflow, or ceramic tile and stone for a cool surface. Avoid fleece, plush and memory foam in hot weather because they hold heat.

Is it safe to put ice in a cat bed?

Not directly. Freeze a water bottle, wrap it in a thick towel, and put it under a cotton pad on half the bed so your cat can move away. Avoid gel packs a cat could chew open.

Do cats actually use cooling mats and beds?

Many do, especially if the bed sits where they already lie on hot days. Offering a cool spot next to a room-temperature spot gives your cat a choice, which makes it more likely to be used.

Where should a cat sleep in a hot apartment?

Low down, out of direct sun, in an interior room like a bathroom or hallway with a hard floor, with water nearby and gentle airflow in the room.

When is a hot cat an emergency?

Panting, drooling, bright red gums, wobbling, vomiting or collapse are emergency signs. Cool your cat gently with damp towels and call your vet or emergency clinic right away.
