If you'd rather not plug anything in, the K&H Self-Warming Pad reflects your pet's own body heat. For a garage or porch, K&H's Lectro-Soft has a steel-wrapped cord. ## Key takeaways - K&H's heated beds use a pet-activated thermostat, so the bed may not feel warm to your hand when it's empty. - The Lectro-Soft outdoor bed has a steel-wrapped cord, but K&H still doesn't recommend it for pets that chew. - The ASPCA says pets need a warm place to sleep, off the floor and away from drafts. ## Products (chosen from listings, not tested) 1. **K&H Thermo-Kitty Heated Cat Bed, Small 16 in** (details: https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07HML9YLD) — The heated cup bed to buy for an indoor cat who sleeps curled up. - Pros: 4-watt heater that warms when your cat is in the bed, per K&H; 6-inch foam walls; removable heater and machine-washable cover; Small for pets under 15 lb, Large 20 in for over 15 lb - Cons: Feels barely warm to your hand when empty, which K&H says is by design 2. **K&H Thermo-Kitty Heated Mat, 6W** (details: https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B08ZBZ23QR) — The mat to put where your cat already naps. - Pros: Warms to about 102°F when your cat lies on it, per K&H; 25 x 12.5 inch reversible mat that goes on a bed, sofa or perch; Removable 6-watt heater; washable cover - Cons: Flat, so it suits cats that stretch out more than burrowers 3. **K&H Lectro-Soft Outdoor Heated Pet Bed, 18 x 14 in** (details: https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B000ICGJZK) — For outdoor and barn cats, or a dog that sleeps in the garage. - Pros: Waterproof outdoor bed with a 5.5 ft steel-wrapped cord; Thermostat warms to the pet's normal body temperature when in use; 20 watts; fleece cover included - Cons: K&H says it is not recommended for pets that chew; For sheltered areas only, not open ground 4. **K&H Self-Warming Cat Bed Pad, 21 x 17 in** (details: https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PF1KYYK) — The low-cost, no-plug option for a warm house or a cat that chews cords. - Pros: Reflects your pet's own body heat; no electricity; Reversible plush sides; machine washable; Fits on furniture or inside a bed or crate - Cons: Makes a slight crinkle that noise-sensitive cats may dislike, per K&H 5. **K&H Self-Warming Crate Pad, Large 25 x 37 in** (details: https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PKDNRZX) — The crate pad for a dog that sleeps in a crate in a cool room. - Pros: Self-warming material, no cord in the crate; Corner slits to fit a crate and a non-slip bottom; Machine washable microfleece - Cons: Thin; add an orthopedic bed for older dogs 6. **Petmate Aspen Pet Self-Warming Round Bed, 19.5 in** (details: https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B00DJRCQBW) — A self-warming round bed for a cat or small dog that likes to burrow. - Pros: Mylar layer reflects body heat, per Petmate; Plush sides for burrowing; non-skid bottom; 16 x 16 inch sleeping area for cats and small dogs - Cons: Small sleeping area; too small for medium dogs When the house cools down, the warmest spot you can give a cat or small dog is a bed that holds heat. There are two kinds: heated beds that plug in, and self-warming beds that reflect your pet's own body heat. For an indoor cat, the [K&H Thermo-Kitty Bed](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07HML9YLD) is the plug-in pick, because its 4-watt heater only warms up when your cat is in it. If you'd rather not have a cord, the [K&H Self-Warming Pad](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PF1KYYK) costs a fraction of the price. We haven't tested these beds. We compared them on their Amazon listings, checked through Amazon's product API on publication day; every one is sold by Amazon. ## How we chose We started with K&H, which makes most of the heated pet beds sold on Amazon and lists wattage, thermostat behaviour and cord details for each. We picked one heated bed, one heated mat and one outdoor bed, then two self-warming pads and a self-warming round bed for homes where a cord is a bad idea. We left out human heating pads, which aren't designed for pets to lie on unattended, and anything without a stated thermostat. ## Heated or self-warming? | | Heated (plug-in) | Self-warming | |---|---|---| | How it warms | Low-wattage heater with a thermostat | Reflects your pet's body heat | | Best for | Senior, thin-coated or outdoor pets; cold rooms | Most healthy pets in a heated house | | Cord | Yes | None | | Pets that chew | Not recommended | Fine | | Washing | Remove the heater first | Machine washable | Older pets and thin-coated breeds often benefit most from extra heat. If your pet has arthritis or is losing weight, mention it to your vet; a warm bed helps comfort but doesn't replace treatment. ## The six beds ### 1. K&H Thermo-Kitty Bed: best heated bed for indoor cats A cup-shaped bed with 6-inch foam walls and a 4-watt heater controlled by a thermostat. K&H says it warms only when your cat is inside and otherwise stays at or just above room temperature, so don't judge it by touching an empty bed. The heater comes out for summer, and the cover is machine washable. The small 16-inch size is for pets under 15 lb; the 20-inch is for heavier cats. **Buy it if** your cat sleeps curled up. **Skip it if** your cat chews cords. ### 2. K&H Thermo-Kitty Mat: best for an existing favourite spot The same pet-activated idea in a flat 25 x 12.5 inch reversible mat. K&H says it warms to about 102°F when your cat lies on it. Put it on the sofa, a window perch or inside a bed your cat already uses. The 6-watt heater is removable for washing. **Buy it if** your cat already has a spot and you want to warm it. **Skip it if** your cat likes walls around it. ### 3. K&H Lectro-Soft Outdoor Bed: best for a garage or porch Built for sheltered outdoor spaces like a garage, shed or barn: waterproof, with orthopedic foam, a fleece cover and a 5.5-foot steel-wrapped cord. The thermostat warms the surface to a pet's normal body temperature when it's in use. Even with the steel wrap, K&H says it is not recommended for pets that chew. **Buy it if** you have outdoor or barn cats, or a dog that sleeps in the garage. **Skip it if** your pet chews. The ASPCA's view is that if it's too cold for you, it's probably too cold for your pet: [keep pets inside](https://www.aspca.org/pet-care/general-pet-care/cold-weather-safety-tips) when you can, with a warm bed off the floor and away from drafts. ### 4. K&H Self-Warming Pad: best with no cord No electricity: the plush material captures your pet's body heat and reflects it back. It's reversible, machine washable and fits on furniture or inside a bed or crate. K&H notes a slight crinkle sound that most cats like and noise-sensitive cats may not. **Buy it if** you want warmth with no cord in reach. **Skip it if** your cat startles at crinkly sounds. ### 5. K&H Self-Warming Crate Pad: best for dog crates The same self-warming material in a 25 x 37 inch crate pad, with corner slits to fit and a non-slip bottom. It's thin, so an older dog may need it on top of an orthopedic bed. **Buy it if** your dog sleeps in a crate in a cool room. **Skip it if** your dog needs joint support; see our [orthopedic dog beds](https://petprooflab.com/home-beds/orthopedic-dog-beds). ### 6. Petmate Aspen Self-Warming Round Bed: best for burrowers A round faux-lambswool bed with plush sides and a Mylar layer inside that reflects body heat, per Petmate. The sleeping area is 16 x 16 inches, so it fits cats and small dogs. **Buy it if** your pet likes to burrow. **Skip it if** your dog is medium-sized or larger. ## All six compared | Bed | Type | Power | Size | Cord | Amazon price | |---|---|---|---|---|---| | [K&H Thermo-Kitty Bed](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07HML9YLD) | Heated cup | 4 W | 16 in (pets under 15 lb) | Yes | see the current Amazon price on the page | | [K&H Thermo-Kitty Mat](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B08ZBZ23QR) | Heated mat | 6 W | 25 x 12.5 in | Yes | see the current Amazon price on the page | | [K&H Lectro-Soft Outdoor](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B000ICGJZK) | Heated outdoor | 20 W | 18 x 14 in | Steel-wrapped | see the current Amazon price on the page | | [K&H Self-Warming Pad](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PF1KYYK) | Self-warming | None | 21 x 17 in | No | see the current Amazon price on the page | | [K&H Self-Warming Crate Pad](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PKDNRZX) | Self-warming | None | 25 x 37 in | No | see the current Amazon price on the page | | [Petmate Aspen Round Bed](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B00DJRCQBW) | Self-warming | None | 19.5 in round | No | see the current Amazon price on the page | ## Using a heated bed safely - **Run the cord where your pet can't chew it**, and use heated beds only with pets that leave cords alone. - **Indoor beds stay indoors.** The Thermo-Kitty products are for indoor household use only, per K&H. - **Give your pet a way off the heat.** Put the bed where your pet can move to a cooler spot. - **Take the heater out before washing,** and check the cord for damage when you put it back. - **Puppies, kittens and pets that can't move easily** should be supervised on any heated surface.

K&H designs its beds to stay plugged in: a low-wattage heater and a thermostat that warms only when a pet is using the bed. Follow the maker's instructions, keep cords away from pets that chew, and give your pet a cooler spot to move to. ### Why doesn't my heated cat bed feel warm? K&H's pet-activated beds stay at or just above room temperature when empty and warm up when your pet lies on them. K&H explains how to test this in the listing; touching the empty bed isn't a reliable check. ### Do self-warming beds really work? They don't make heat; they reflect your pet's own body heat back. In a heated house that's usually enough for a healthy pet. For a senior, thin-coated or outdoor pet in a cold space, a heated bed adds more warmth. ### Can I use a human heating pad for my pet? Pet beds are designed for pets lying on them unattended, with low wattage and a thermostat. Use a bed made for pets rather than a human heating pad, and follow its instructions. ### Do cats need a heated bed in winter? Not all cats. Indoor cats in a warm house often do fine with a self-warming pad. Senior cats, thin or hairless breeds, and cats in a cold room or garage are the ones most likely to use a heated bed. ## The Bottom Line Indoors, buy the [K&H Thermo-Kitty Bed](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07HML9YLD) for a cat that curls up, or the [Thermo-Kitty Mat](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B08ZBZ23QR) for a spot it already loves. For a garage or porch, the [Lectro-Soft](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B000ICGJZK). No cord wanted? The [K&H Self-Warming Pad](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PF1KYYK), or the [crate pad](https://petprooflab.com/home-beds/heated-pet-beds-and-self-warming-pads#product-B07PKDNRZX) for a dog. --- *PetProofLab is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
