As above, the extreme weather one, used 10 months of the year 24-7 on a cold floor under a thick cushion of pet bed. It has not been used outside.Cheaper than normal heated beds because of the longevity (has outlasted 3).It is also better at warming the whole bed not just one area of the cushion and a floor like concrete doesn’t steal the heat. I got this one specifically because it could be left on all the time unattended indoors, it’s over engineered for this purpose but I figured that was the safest. It’s a board of hard plastic so no worries about wires breaking inside foam or fabric and burning. It feels warm to touch all the time, like putting cold feet on a warm person. Was ordering one for a second pet and am amazed this one is from 8 yrs ago

This product is A-MAZING! Works exactly as described. I built an outdoor house for a feral cat that we've been feeding for the past 3 winters and it took only until the second evening before kitty had adopted his new condo! He now waits inside until the food is put out and quickly retreats to the comfort of the heated bed, to bathe and snooze after finishing. I may not (yet!) have been successful in coaxing this timid little character inside but I now know it can be warm and comfy when it's 20 below!! Beautifully constructed and the faux sheepskin removes easily and washes like a charm!

I used this outside at around -25c in an insulated shelter. The abandoned cat would go back in immediately after eating and stayed alive throughout the week so product worked as intended. Next couple of weeks dropped into -40c and lower so we brought the little bugger in and kenneled him till he passed vet inspection as we have 2 house cats we wish not to get any contact disease. We gave him a permanent home at that point. I did not have the heart to test the product at those lower temperatures. My indoor cat is cold often and demands lap time warmth. This set up on the couch cushion kept her quite content and she regularly naps on it so the temperature regulation feature works as advertised. I don't think there is a better product out there for cold Alberta winters

We're using this pad for barn cats who live in the unheated barn year round in Canada. It's our 2nd one and they both work reliably and the cats love it.

I've had one of these before but had to leave it behind when I moved house. It works very well and gives just enough warmth to keep an outdoor cat comfortable in a covered, sheltered area. The description of it on Amazon is poor (and incorrect) so I'll try and elaborate here.It is a hard plastic pad with a 5ft (not 500 ft, as will probably be obvious)cord which is covered with a spring like metal cover to prevent chewing.It is 18 1/2 inch x 12 1/2 inch and about 1/2 inch thick.Rated at 40 w you can leave it on 24/7 without breaking the bank or put it on a timer. It comes with a "free" fleece cover, which makes it a little more comfortable for the cat to lie on. They warn against covering it with anything else and maybe because the heat output is relatively low, it would not penetrate anything too thick anyway.The instructions warn against using it with an extension cord, but to be honest most people would use one due to where the pad will be located. I can't see a problem with this if you use a good heavy duty cord and plug it into a GFCI outlet.You will find the price on Amazon hard to beat. The last one I bought cost nearly twice this from a pet specialty outlet.

I use a lot of K&H products, both for my own cats and for the strays in my neighborhood that I take care of. I used heated cat beds inside. My cat Max passed away from cancer this Summer, and the K&H heated beds I got for her were a source of great comfort while she was going thru chemo. Outside, I use heated cat shelters for the strays. I placed the shelters in my shed where strays can go to rest, sleep and be safe, protected from dogs by my fenced yard. This pad I bought to put into a wooden cat shelter (made by another supplier) that I installed on my deck. Since this shelter is actually outside, I was looking for the best possible heated pad for our extreme Quebec winters. The description of this heated pad said "extremee weather" and upon opening the box, I knew I had purchased the right pad. It's rigid, instead of being pliable, and after testing it before installing it, I know it will help keep some strays warm this Fall and Winter. The duvet cover is really soft and comfy. All in all, a great product, and I am grateful that K&H sells heating pad separately that can fit many different cat shelters.

This is an amazing product that actually works. We were trying to save a feral cat that would not come indoors and was living in very cold conditions. A structure was built for him and the outdoor heated mat was put in. It saved his life. We have experienced -50 degree weather and he is as snug as a bug.

My outdoor cat loves it

My K & H Cat House is 2 1/2 years old. Many months ago, a very timid, stray cat became "a regular" visitor to my farmer's porch. I feed and water him (her?) daily and provide bedding and blankets for it to sleep upon. When the forecast called for the first severe Arctic blast to hit, I ordered the K & H Extreme Weather electric Heated Bed w/ free Fleece Cover. I paid for super fast delivery, and even in M.L King'sBirthday, it arrived in less than 48 hours. I tested it out as the instructions say, and it felt warm....not dangerously hot, but soothing. Fine! So I took it out to the porch to put in the car house, but it was about 2" longer than the cat house. I had to improvise in order to keep it lying flat on bottom of the car house. I folded the back walk, extending the length of the floor. I sealed the (now shorter) rear wall with duct tape to keep draftiness to a minimum. It worked out very well, with my porch being covered, but not fully enclosed. Because this cat is a total scaredy cat who scurried under the porch, even when I approach to feed him.... I keep the front AND rear openings open, with the plastic flaps taped up and open so he won't feel trapped - ever! I put his canned food inside alobg the corner. Both to keep food from freezing, and to lur him in the house to discover the fact that it is now heated. My fears that he wouldn't figure it out were unfounded, as the 1st overnight temps were in the mid teens, F , with a biting west wind howling between 20 - 30 m.p.h. giving the wind chill values of 4 above to 5 below zero, F. And when it started to get light out the next morning I was thrilled to find him in his heated sanctuary, where he came out and scurried under the porch so I could remove the empty feed bowl and replace it with breakfast. I leave the dry food out of his house so that there is as much room as possible. The suggestion I have us measure heated flooring / pad or buy the K & H Heated Outdoor House, to avoid my minor mismeasuring mishap. But I already had an unheated version of the house. I live 20 miles north of Boston, as I write this it's 19 degrees with wind chill value of 5 degrees. The elect. chord is housed inside sturdy metal, so it's nearly impossible for a critter to chew at it. The free Fleece Cover that comes w/ unit is nice, but attaches with elasticized bands on each corner. I opted to purchase K & H Extreme Weather cover for the unit. It slips on, and zips closed, completely enveloping the unit, which is made from a sturdy plastic. The zipping cover was only 8 or 9 bucks, with no worries that it will come off. The material is soft and breathable and made for this item, as well. I recommend this product, as the little stray has truly been a constant resident during this extremely brutal Arctic cold snap! So happens, a big N'orEaster is in the forecast, and could dump a foot + in my area in the next 48 - 72 hours. Since my porch is exposed, I will get some heavy guage, clear plastic sheeting to protect a large portion of the porch; using a few small nails along the inner area from the roof to below the floor, covering the lattice. This will keep the cat's sanctuary free from snow, and prevent water from saturating the car house or the electrical aspect of the heated flooring and fleecy covering. Monetarily, these products are reasonably priced. The stray cat isn't as well off as my 2 house cats, or my 1 indoor / outdoor cat but is FAR BETTER OFF than the countless, helpless animals who are exposed to howling frigid winds and zero degrees Fahrenheit temps. The picture I included was during the first full day, proving how I shouldn't have worried about whether the stray would figure out what to do!! The light blue sliver of color inside on left is the feed bowl I tucked inside. Like I said, even on this severely cold, cloudy day, the canned wet food stayed moist but totally unfrozen. Even though the unit is completely encased in a very sturdy plastic, I do not put water in there, just to be 100% safe! I am very very happy with the K & H products!

Works great and without electricity

In July 2011, a feral mom brought her three babies to our porch. (How did she know we'd take care of them?) We did TNR on the babies and mom, then turned them loose. We bought a small doghouse at the Farmers Co-op, closed off the big door, and made two small doors -- one at either end. (The cats wouldn't go in unless there were two options for escape, I guess.) We lined the walls with heat-reflecting mylar. We put it on the screen porch and the kittens would go in and cuddle as the days got colder. Then, as temps got lower, we started to worry that they might not survive, and we wondered if they'd be OK the next morning, so we tossed and turned every night. Then we saw this pad on Amazon and ordered it in Sept. 2011. DH cut a small hole in one of the floor slats of the doghouse for the cord, and we plugged it in. The babies loved it. By this time, their mom had cut them loose and she only came by to eat and then leave. Knowing the babies were warm, we were able to sleep through the night, pretty confident they'd be OK as far as weather was concerned.In Nov. 2011, with the threat of coyotes and evil raccoons in the area, we brought the babies indoors to join our existing four (too many cats!) We put the doghouse and kitty pad in the garage for storage. This summer, Mom Darth started to stick around the screen porch and visit with her kids through the French door window. (Abandon three babies, and then return to get all friendly a year later -- sounds like a "Lifetime" movie!) We set up the doghouse with the kitty pad a couple weeks ago, and Darth is loving her warm place. She's truly feral with no chance of taming, so we're happy she has a place where she knows she can be warm and safe. We don't worry and there's a lot to be said for peace of mind.We also bought one of the thermostat cubes (on at 35 degrees) to use in conjunction with the pad, but the cube doesn't work. We just plug in the pad when it gets down to about 40 degrees, and generally don't use it 24/7 -- just when it's sure to be cold. And we've looked at outlets that can be activated via remote control; that might be a better option than do the plug and un-plug on cold days/nights.Will be ordering another pad for backup in case this stops working. But so far it's been excellent.

I bought the Millard Indoor/Outdoor Heated Pet Pad and the K&H Manufacturing Extreme Weather Heated Kitty Pad at the same time and put them both in my outside kitty house to compare them side by side, as I expect that I will have to buy more at some point in the future and wanted to know which would work best for my needs. So far both have been performing well outside after several weeks in constantly freezing weather with occasional dips to sub-zero temperatures. (I did go out in the sub-zero temperatures to see if both were still warm to the touch, and they were.) They are in a small, insulated shelter made from an old corner kitchen cabinet, with an old felted wool sweater repurposed as door flaps. The Millard pad is warmer to the immediate touch while the K&H pad is not quite as warm immediately, but heats up in a minute or so. The other surfaces inside the shelter are noticeably warmer than the outdoor surfaces, but when I put food and water bowls in the shelter too, the water and dry food froze, so the ambient temperature is still not enough to prevent freezing. I already had the K&H Heated Kitty Cafe (two heated, stainless steel bowls) even before I had the shelter, and it works perfectly and keeps food and water from freezing even when set on a covered porch but still exposed to the outdoor, sub-zero air temperatures. So I put the Kitty Cafe inside the shelter too.As both have been performing well, the biggest difference I see so far is that the Millard plug is grounded (three prong) whereas the K&H pad is a standard (two prong) indoor plug, and the Millard cord is wrapped in PVC whereas the K&H pad is wrapped in a steel spring. The K&H box did have helpful instructions on how to modify a dog or cat house so as to have the cord exit through a rear or side wall instead of out the front door (drill with a 1 1/4" spade bit).Bottom line: So far I am happy with both pads and they seem comparable in performance and price, but the minor difference in cords and plugs may help others decide between them.

Several years ago, a cat came out of the cornfield into my yard while I was mowing the grass. I thought it was the neighbors, but turns out it was truly a feral cat, i.e. fearful of contact with humans, other animals, etc.I started feeding the darn thing and once you do that, you have a cat, like it or not. Later, I contacted a local feral cat program and had this cat neutered. Trapping and transporting him to the vet was a challenge, but for the small fee, I did not want this cat wandering the neighborhood (semi-rural area) and creating litters of kittens. Lastly, while I couldn't take him to the vet (he is a true feral cat), I took pictures a very swollen paw on my Ipad and showed them to the vet who prescribed antibiotics to minimize the possibility of infection.Then winter came and I purchased the kitty camper (through Amazon) which is a small dome like tent for cats with a built-in heating pad to get him through the winter.Then the neighbor cat caught on about the food and the heated kitty camper so I purchased this item as a second heating pad and placed it in a old dog house I had for my Shih Tzu. Now the 2 cats don't have to argue over who gets the heating pad and this pad was more economical the buying another kitty camper. I like both, but the neighbor's cat is just an occasional visitor and if he does visit he has a warm place to stay.I purchased this heating pad because it was manufactured by the same company that makes the kitty camper and I already knew that was a good product.I am not a cat person so I will never have a cat inside my house. But feral cats help keep the mice, moles, voles, etc. under control so having a few neighborhood cats is a good idea.P.S. I also bought a heated water dish to provide water for the cats. Also purchased through Amazon.
