The K&H Thermo-Kitty Bed is the heated pet bed I would buy for an indoor cat. It draws 4 watts and costs $59.98 for the 16-inch size on K&H’s own store. For a dog, or for any pet sleeping in a cold garage or shed, pick the K&H Lectro-Soft Outdoor Heated Bed. The 19 x 24 inch size is $74.99 at PetSmart. If you want no cord at all, the K&H Self-Warming Nuzzle Nest is $36.98 at PetSmart.

I have lived with cats for years, and I have had dogs and a pony too. Every cat I have shared a house with sooner or later found the one warm spot and claimed it. A heated bed gives that habit a permanent address. If you are setting up for a new cat, my new cat starter kit covers the rest of the shopping list.

Which Heated Pet Bed Matches Your Pet?

Four beds cover the decisions most owners face: indoor or outdoor, cat or dog, electric or not, and how much cord you can live with. The table lines them up. The sections below then walk through each choice in order.

Bed	Made for	Power	Where it can go	Price read October 18
K&H Thermo-Kitty Bed, 16 in	Cats, small dogs	4 W, thermostat	Indoors	$59.98 at the K&H store (20 in: $70.98)
K&H Lectro-Soft Outdoor Heated Bed, 19 x 24 in	Dogs and cats	40 W, thermostat	Indoors or outdoors	$74.99 at PetSmart
K&H Lectro-Soft Outdoor Heated Bed, 25 x 36 in	Dogs and cats	60 W, thermostat	Indoors or outdoors	$102.99 at PetSmart
K&H Self-Warming Nuzzle Nest, 19 x 24 in	Cats, small dogs	None	Indoors	$36.98 at PetSmart
K&H Pet Bed Warmer, small	Goes inside a bed you own	4 W, thermostat	Indoors	$18.59 at PetSmart

Where each figure comes from: the Thermo-Kitty price is from K&H’s own store. The other prices are from PetSmart’s product pages, and every wattage is from K&H’s product pages. The retailer matters. K&H’s store lists the Lectro-Soft at $69.98 for the medium and $99.98 for the large. It lists the small Bed Warmer at $29.98. The same product can sit $2 to $11.39 apart depending on where you click.

Should a Heated Pet Bed Be Indoors or Outdoors?

Decide this first, because it removes half the options. K&H’s Thermo-Kitty page describes an indoor cat bed. The Pet Bed Warmer page lists “Outdoor Use: No.” The Nuzzle Nest page says the bed is not built to return enough body heat for the cold outdoor temperatures of winter.

Only the Lectro-Soft Outdoor Heated Bed is sold for both. K&H’s page says it suits sheds, garages, barns and sheltered areas. But outdoors still means power. The bed runs on 110/120 V current only, and its 5.5-foot cord is steel-wrapped. K&H’s FAQ calls the bed water-resistant and says not to immerse it. It also says not to put the bed where standing water can form. A dry, covered spot within cord range of an outlet is the realistic site. A shed with no outlet rules this bed out.

How Big Should a Heated Pet Bed Be for a Cat or Dog?

Size is the second decision. K&H publishes dimensions and wattage by size, but no pet-weight limits for these four beds. The Thermo-Kitty comes in 16 and 20 inch rounds with 6-inch walls, and K&H says both suit small dogs too. The Lectro-Soft comes in three sizes. They are 14 x 18 inches at 20 W, 19 x 24 inches at 40 W and 25 x 36 inches at 60 W. The Nuzzle Nest is 19 x 24 x 6 inches and aimed at cats and small dogs.

Without a weight chart, measure the pet. Lay a tape along your dog or cat in its usual sleeping curl, then again stretched out. Compare both numbers with the bed’s footprint. A bigger bed also means more watts, so the 60 W large Lectro-Soft costs more to run than the 40 W medium. The cost table below shows by how much. Big dogs often need joint support more than heat, and my guide to orthopedic dog beds for large and giant breeds covers that side. For an older dog, the senior dog comfort guide lists what else helps.

Thermostat or Self-Warming: Which Heated Pet Bed Do You Need?

A thermostat bed uses electricity to make heat. According to K&H, the Thermo-Kitty and Lectro-Soft warm to about 102°F when a pet lies on them. K&H calls that the approximate body temperature of dogs and cats. Unoccupied, they sit about 10 to 15°F above the surrounding air. K&H also says the beds are not pressure sensitive. The heat depends on the pet’s body insulating the surface, not on how much the pet weighs.

A self-warming bed has no cord. The K&H Nuzzle Nest uses metalized plastic, the same kind of material as space blankets. It reflects the pet’s own heat back at the pet. An empty Nuzzle Nest is only a bed, and K&H points it at areas near room temperature. Choose self-warming for a cat that already sleeps in a heated room and chews cords. Choose a thermostat bed when the spot itself is cold.

What Cord and Safety Rules Come With a Heated Pet Bed?

Follow the maker’s page first and your vet second. K&H’s pages for these beds repeat the same core warnings. Read them before you plug anything in.

• No extension cord. The Thermo-Kitty page says MET requires the statement “Do not use with extension cord” on the product. The cord is 5.5 feet, so the bed has to sit near a wall outlet.
• No on/off switch. The Thermo-Kitty, Lectro-Soft and Pet Bed Warmer stay on while plugged in. The Warmer’s page calls it designed for 24/7 operation. All three pages also say MET Safety Laboratories suggests unplugging the bed if you leave home on an extended vacation.
• Let the pet leave. K&H says not to place a bed in a confined area where the pet cannot step off it.
• Ask a vet for the vulnerable. K&H says to consult a veterinarian before using a heated bed with young puppies or kittens. The same goes for convalescent pets, pets recovering from surgery, and any animal that cannot move off the pad on its own.
• Chewers. The Lectro-Soft page says it is not recommended for destructive pets.
• Nothing on top. For the Lectro-Soft, K&H says to place nothing on the bed except the provided cover, because blankets or towels can trap heat. The Pet Bed Warmer goes inside a bed with at least half an inch of padding between it and the pet.

Have Any Heated Pet Beds Been Recalled?

K&H’s pages state that the beds are MET Labs certified. I also searched the Consumer Product Safety Commission’s recall database on October 18, 2026 for K&H, Thermo-Kitty, Lectro-Soft, Nuzzle Nest, bed warmer and heated pet beds. It showed no recall for any of the four beds here. The heated pet products it does list are older, and both involved fire risk. One was a 2010 recall of power adapters sold with PetSafe Heated Wellness Sleepers. The other was a 2012 recall of World Class indoor pet heating mats. Check the recall database again before you buy. A clean search today does not cover tomorrow.

What Does a Heated Pet Bed Cost to Run Each Winter?

A winter of electricity costs less than the bed itself, in every case here. The math is rated watts times 24 hours times 30 days, divided by 1,000 to get kilowatt-hours. Then multiply by your electricity rate. For the rate, I used the U.S. Energy Information Administration’s July 2026 average residential price of 18.31 cents per kilowatt-hour. It comes from Table 5.3 of its Electric Power Monthly, released September 24, 2026. Swap in the rate on your own bill, because states differ a lot.

Bed	Rated watts	kWh per 30 days	Cost per 30 days	Cost for 150 days (Nov to Mar)	Bed price	Bed plus one winter
K&H Thermo-Kitty Bed, 16 in	4	2.88	$0.53	$2.64	$59.98	$62.62
K&H Pet Bed Warmer, small	4	2.88	$0.53	$2.64	$18.59	$21.23
K&H Lectro-Soft, 19 x 24 in	40	28.80	$5.27	$26.37	$74.99	$101.36
K&H Lectro-Soft, 25 x 36 in	60	43.20	$7.91	$39.55	$102.99	$142.54
K&H Self-Warming Nuzzle Nest	0	0	$0.00	$0.00	$36.98	$36.98

How Is the Running Cost Worked Out?

Here is one row worked out. The medium Lectro-Soft is 40 W, so 40 × 24 × 30 ÷ 1,000 = 28.8 kWh, and 28.8 × $0.1831 = $5.27 per 30 days. Five such months is 144 kWh and $26.37. These are ceilings. The table assumes the heater runs at full rating every hour. K&H describes the beds as thermostatically controlled but publishes no duty-cycle figure, so I did not guess one.

Other Pet Bed Warmer sizes draw more, per K&H’s page. The medium is 6 W, the large 13 W and the extra large 22 W. At the same rate the extra large works out to $2.90 per 30 days. The Lectro-Soft’s small size is 20 W, or $2.64 per 30 days.

Replacement covers are the other recurring cost. K&H lists Lectro-Soft replacement covers at $14.95, $16.95 and $18.95 by size, and every size showed as sold out on October 18. Add the $16.95 medium cover and the medium Lectro-Soft’s first winter reaches $118.31 ($101.36 + $16.95). K&H’s Thermo-Kitty page lists no replacement cover price. Instead, K&H says to wash the cover and cushion on a gentle cold cycle and line dry. I ran the same watts-times-hours arithmetic for human bedding in my electric blankets guide, if you want a comparison.

What Is Each Bed Like to Own?

K&H Thermo-Kitty Bed: A 4-Watt Heated Bed for Indoor Cats

The Thermo-Kitty is a round foam cup with 6-inch walls, which suits a cat that likes to curl up and feel the sides. Its 4-watt heater is removable and thermostatically controlled, and the cover comes off for washing. K&H sells it in Mocha or Sage at $59.98 for the 16-inch size and $70.98 for the 20-inch. The cord is 5.5 feet, and the bed carries a one-year limited warranty.

Skip it if your cat chews cords, or if you want a switch. There is none, so the bed is on whenever it is plugged in.

K&H Lectro-Soft Outdoor Heated Bed: Heat for Dogs and Cold Rooms

This is the only bed here for a dog with a cold sleeping spot. PetSmart’s page lists a soft orthopedic foam base, a removable fleece cover and a thermostat that holds about 102°F when a pet is on the pad. At PetSmart the 19 x 24 inch size is $74.99 and the 25 x 36 inch size is $102.99. Only the cover washes, on a gentle cycle in cold water. K&H says the bed itself should not go in a washing machine, so wipe it with a damp towel and mild dish soap.

Skip it if your dog chews, since K&H says it is not recommended for destructive pets. Skip it too if you cannot keep the cord out of reach.

K&H Self-Warming Nuzzle Nest: A Cordless Bed for Cats and Small Dogs

The Nuzzle Nest is a 19 x 24 x 6 inch bolster bed at $36.98 on PetSmart. K&H says no electricity is required, and the bed is machine washable on a gentle cold cycle. Its limit is the one K&H states itself: keep it indoors, in a space near room temperature.

Skip it if the room itself runs cold, because a reflective layer can only return the heat your pet makes.

K&H Pet Bed Warmer: A Heated Insert for a Bed You Already Own

If your pet already loves a bed, the Pet Bed Warmer slides inside it. The small is $18.59 at PetSmart and 4 W. The larger sizes go up to 22 W. K&H says it is indoor only, thermostat controlled and MET Labs certified. The warmer should never come into direct contact with the pet. K&H calls for at least half an inch of padding above it, and warns that a human heating pad would be much too warm for a pet.

Skip it if your pet’s bed is thin. A flat mat may not give you the half inch of padding K&H calls for.

What Do Owners Ask Before Buying a Heated Pet Bed?

Can a Heated Pet Bed Use an Extension Cord?

No, according to K&H. The Thermo-Kitty page says MET requires the statement “Do not use with extension cord” on the product, and the Lectro-Soft FAQ says the same. Plug the 5.5-foot cord straight into a wall outlet, which means placing the bed within that distance of one.

Should I Unplug a Heated Pet Bed When I Leave the House?

K&H’s beds have no on/off switch. The Pet Bed Warmer page calls that bed designed for 24/7 operation, yet all three pages say MET Safety Laboratories suggests unplugging the bed if you leave home on an extended vacation. Ask your vet how that applies to your pet, and follow the maker’s page for any bed you buy.

Can Kittens or Puppies Use a Heated Bed?

Check with a veterinarian first. K&H’s pages say to consult one before using a heated bed with young puppies or kittens, convalescent pets, pets recovering from surgery, or any animal that cannot move off the pad on its own. K&H also says not to place a bed where the pet cannot leave it.

How Warm Does a Heated Pet Bed Get?

K&H says its thermostat beds warm to about 102°F when a pet is lying on them, roughly a dog’s or cat’s body temperature. Unoccupied, the surface runs about 10 to 15°F above room air. K&H adds that the beds are not pressure sensitive, so heat depends on the pet’s body insulation, not its weight.

Does a Self-Warming Pet Bed Work Without Electricity?

Yes, but it depends entirely on the pet’s own heat. K&H says the Nuzzle Nest’s metalized plastic reflects the pet’s body heat back, with no electricity required. It is meant for rooms near normal indoor temperature, not for cold outdoor spaces.

Which Heated Pet Bed Would I Buy for Cold Weather?

I would buy the K&H Thermo-Kitty Bed for an indoor cat, because at 4 watts it costs about 53 cents per 30 days even at full rating around the clock. For a dog, or a spot that is cold in earnest, I would buy the K&H Lectro-Soft Outdoor Heated Bed in the 19 x 24 inch size at $74.99. I would keep it in a dry, covered place within cord range of an outlet. If your pet chews cords, the K&H Self-Warming Nuzzle Nest at $36.98 is the one I would pick, in a room that stays warm.

Every pick here is a K&H product, because the in-stock heated beds I found at PetSmart on October 18 were all K&H, and K&H publishes the wattage and safety rules for each one. For a cordless bed from another maker, PetSmart lists the FurHaven Convertible Self-Warming Cuddle Pet Bed at $24.99 in the large Rainbow version, built on the same reflected-heat idea. Whichever you choose, read the maker’s page for it. Ask your vet about anything the page flags. More ideas live in Pet Care & Supplies.
