heat bulb wattage for outdoor cat house

[bee]

I am planning on building an outdoor cat house here in Manitoba where temperatures get pretty frigid in the winter, as low as -48 degrees or so Celsius. I want our 2 outdoor cats to live in relative comfort, but I don't know how high the wattage should be on the heat bulb that I put inside the cat house, just so that it at least doesn't freeze. The house will be about 5x2 feet and insulated, but it won't be completely sealed since there will have to be a small (probably 6x6") swinging door or something for the cats to get in and out. So what wattage of heat lamp should I get, or would a regular light bulb work? (Still, what wattage?) What would be the most frugal as far as electricity costs in winter, but still keep the little cat house above freezing in -40s (Celsius) ?

There are heat lamps with thermostats and thermostats made for heat lamps if that might work better. Would a heating pad be a viable alternative? There are also ceramic heat emitters that don't put out visible light if that would matter.

I bought a K&H house and it came with a 20w heating pad:

It usually doesn't get much below 0 F here but it worked out well. In
the winter the cat is inside most nights but when I go to work he goes
out so it gives him someplace to hang out in a pinch but I think he's
found a crawl space he prefers.

K&H has a selection of heat pads. One good thing it did was motivate me
to put a weatherproof receptacle and ground fault outlet on the outside
box. I didn't want to fry the cat if he decided the pad was a chew toy.

See, even your K&H house serves to make you look cool, just like your cool
cat does, and your cool guns do, and your entire cool life does, bigmouth.

Get one of the small heaters with a thermostat and blower in it, available at Walmart.
It will actually keep the temp near a fixed point, which is what you want.
