You may need to train your cat to use the house by feeding them inside. They will see how warm and cozy it is in there and before you know it they will be using it on their own.

We keep our cat houses out all year long but we only feed them inside on very cold days. They are plugged in all winter, day and night. In the spring we unplug them during the day when the weather is warm and plug them in for the cold nights. During the summer our cats dont use the inside, so we put foam pads on top and they love to lay up there. When we turn the houses on in the fall as the days and nights start to get cold again, we find our cats sleeping inside, they really love their houses!

Having fun checking out their new house.

I've made a similar house for my cat. I am having a problem with the the lid leaking at the hinges when it rains too hard outside. I would caulk it, but I want to be able to lift the lid for cleaning purposes. Any ideas how to keep it from getting wet inside?

I feed an outdoor, homeless cat. I got him a shelter made of large plastic storing crate. It is insulated, and has straw for a bed. Unfortunately, Ginger refuses to enter it. Another cat, who has a home uses it instead. I am very upset. Shall I make the entrance larger? You said place food inside. I am rally desparate. Toronto is known for very cold winters.

is there additional air vents? I know that air does come in the door area but wouldn't the air get stale and contain more carbon monoxide? This would work for our ferel and stray male cats.

I have two heated cat houses in an outdoor enclosed shelter. These houses are made with plywood panels and 1-1/2 inch styrofoam cores. Circular hole as door is covered by cloth flap. Heating system consists of 100 watt long life light bulb (covered by steel can) and Honeywell $10.00 thermostat connected in line. Keeps stray cat/cats warm and comfortable at constant 70 degrees with outdoor temperatures of minus 30. Insulated top panel is removeable to allow for easy changing of light bulb if required. House is equipped with cctv camera which allows for monitoring of food, water, and temperature. Food is removed at night to keep raccoons away.

This is a GREAT idea! We will be making one of these this weekend for our two outdoor kitties! I love my animals, but I DO NOT love having them inside my house. My kids and I like to spend lots of time outdoors with our pets.

pdjinc.com-
you made my mom soooooooooo happy, thank you. She trapped and spayed 14 or 15 ferals in NJ about 4 years ago, 5 are left and she worries about them all of the time. My bf built them a house to match her office 2 winters ago off the ground complete with matching roofline and siding. Winters are tough there however and she wasn't sure it was warm enough inside despite the foam insulation and non contact with the ground.
This winter we put a remote thermometer inside to gauge the inside vs. outside and found the inside temp to be the same and outside minus the wind factor and snow / rain. Searching for a quick fix bc we were only there for a week over the holiday I found your similar story and wonderful instructable.
Thank you soooooooo much for the idea. Although I wasn't able to do the professional job you did mounting the lights bc of the blizzard that had just started, I stuffed the rope lights under the bedding on both interior levels and ran the electric off the same cord as their heated water bowl. Also did a double rope length to give them a heated path to the house from the waterbowl doubling over the lights so some of the snow would melt.
Immediately there was only about 5 degrees difference - overnight that went to 20 degrees and now despite the awful low temps it has normalized and stayed at 60 degrees in their house. My mother keeps the remote temp sensor ($10 at Rite Aid) inside their house and the base inside her office which is on the same property as her home.
Honestly the only thing she has talked to me about since we did the rope light is the rope light and how happy she is that her kitties are warm. She will never talk those cats into being indoor cats but now they have their own indoors and reported to me yesterday that she sees them popping in and out of it.
Thank you, thank you, thank you and God Bless.

Could some sort of a "window" be incorporated in this design? There is a lot of bird watching to be done between naps.

Great project !  Thanks for thinking "inside" the box and sharing.
Two things I would suggest:
1.  After the cat(s) gets used to hanging out in the shelter, put the food somewhere else.  Raccoons, possums, other cats, even rats, will be attracted to the food and the cat could find itself trapped inside or unable to go inside.  Kitty friend could get hurt pretty bad in such case.  If there's any possibility of dogs getting into the yard, I'd put it up where a dog can't get to, as well.
2.  Use a second-hand cooler (thrift shop, garage sale or Craig's List) to reduce use of natural resources, keep something out of the landfill and save money.
RE:  HAY/STRAW   This would be fine, if it's something you have laying around, but most people don't.  How about a cat hammock (as seen in some other "Instructables" with a removable pad for washing?  It would get the kitties a up off the floor, where it's warmer anyway, and provide circulation underneath to dry out the towel when they come in with wet feets. 
RE:  HEATING PAD  I think a heating pad would probably be too hot, besides using more electricity and possibly being a fire risk. Our long-haired cat loves to be outdoors.  Even when inside, he'll hang out in the cold bedroom instead of the cozy living room.  Not all cats like to cozy up by the fire--especially cats who are used to being outdoors.  In a small, well-insulated space like this, the cat's body heat only needs a little supplement to make it toasty.

I really like this build. I am going to make one, but with a couple changes. First off, Hay or Straw is the way to go, so it will dry, as cloth may not. A waterproof heated pad sold at pet stores for heat that could be attached to a thermostat to automatically turn on when it got below "x" temp, I'll have to look that up, to see what a good temp would be. Good stuff, thank you.

i like the idea, but my cats stay inside. all the time. they are afraid of the outdoors. Our youngest, we rescued as a kitten on the side of the road, about 2 days old. She was a feral cat. Her mother abandoned her because(we assume) she suffers from Cerebellar Hypoplasia. omg that cat, even though she cannot walk right, will attack anything, moving or not >_<
Oct 26, 2008. 2:05 PMjgodsey says:
commendable that you rescued them. But why not just take them inside all the time, or at least when it is cold out. It is not like they are true ferals. and why the rope light? they don't need it.
Oct 26, 2008. 6:19 PMjgodsey says:
Thats too bad, our rescue group has found that fighting is very very rare with anything other than Tom cats who would rather be outside. Cats are communal and usually reach a form of detente.

My poor cats have to put up with snakes, dogs, mini komodo dragons and hedgehogs!

This is a great idea. I tried and using the house for some puppies I have. This is great because the dog igloo I have is very damp. With a blanket in the dogloo, the blanket will wick water inside being close to the ground. The cooler is above ground with the lip at the bottom. The only thing that gets wet is when pups go inside. I can quickly clean and replace the blankets inside. I can build mere as I have a few more unused coolers around.

I've been making outdoor stray-cat houses for a while now--much to the displeasure of my neighbors. This looks great--only a couple of suggestions. First, cut the hole up a couple of inches from the bottom, not right at the bottom. The cats can see directly in without crouching down (less scary) and the elevated opening keeps splashing rain and kicked-up snow out better. Second, I get cheap plastic outdoor tables--little ones about 15 inches high and a foot square. I then shove it up against the "house" over the door and tape it to the house with duct tape. This shelters the door opening from blowing rain and snow. They seem to really like having a "front porch" to sit under too. ... Really like the insulated ice box!

good to put hay or staw in the bottom - cause if they track in snow it will melt from the heat. Great cat house!

Once a hierarchy of dominance is established, the cats will not fight anymore. Except to challenge the leader, but these fights are short and few injuries usually occur. The "new" cats have an unfamiliar scent and since they are a "forced" intruder, the current residents will defend the territory. Get the cat's scent on your pant legs, shoes, etc. by rubbing them under the chin and cheeks, and introduce the scent to the other cats. They will get used to the "new" cats scent before even seeing them. I have done this successfully several times. If this doesn't work, bathe them all at once. Group humiliation is a bonding experience. ( this may take several people to accomplish, but it works) The house needs more ventilation, I think, but other than that, good instructable.

If you need more holes for ventilation, why not just cut a few more power cord holes along the top edge of the cooler? That way you get more airflow through the box, but not so much that all the hot air wicks out in winter.

What a cute idea! I have also been adopted by an street cat, but I think I might take him inside for the winter. He already tries to come in quite often. :P
Oct 27, 2008. 10:20 AMjgodsey says:
if he wants to come in, let him in. that type of cat will either never want out again and become a perfectly nice pet, or he will only want to come in from time to time to nap and eat. I have both sorts. i have 22 cats inside today, only 5 are permanent residents the rest are rescues that come and go depending on adoptions, and no one fights ever. sometimes abandoned cats are so happy to be off the street they become your best cat ever.
Oct 27, 2008. 1:07 PMjessyratfink says:
I want to, but I would like to take him to the vet first if possible. I have three kitties inside right now, and I don't want them to catch any bugs! I've had my fair share of awful cat ailments in the past couple of years.
Oct 27, 2008. 2:17 PMjgodsey says:
contact your local no-kill rescue group (call your ACO they will also tell you whom to call), they will help you with the medical expenses, perhaps even direct you to a clinic. We do that all the time, it's finding someone to take them in that's the hard part. If it gets cold, bring him in and shove him in the bathroom, he can winter in there and you can put him back out in the spring. I did that for many years with the 'ferals' who lived in my yard, they wintered in side and once spring came out they went. but they were feral not friendly....well after 5 years of that, they became much more friendly and are now indoor onlies. good luck
