I have been reading about cob building and now that I have an outdoor cat I decided to see if I could build it a shelter for free. For the bottom I used a greenhouse tray that I obtained the last time I bought a flat of plants. For the upper portion I found a scrap of old Formica in the garage. For insulation I lined it inside and out with 1/2″ thick fiber fill that was used as packing around some furniture we bought.
The hubby kept telling me the cat wouldn’t get in it but you can see it did before I could even start putting the cob on it. The cat is inside it in the featured photo but he is so far back he doesn’t show up very well.
I am by no means a cob building expert. If you want to do any cob building I highly recommend you find better instructions than mine. I just used what I had available. I mixed equal portions of sand and clay. Since I didn’t have any straw I used pine needles that I cut into 2″ lengths. I mixed it all together then added enough water to make a moldable clay. Then I applied it to the mold in blobs and used my hands to smooth it all together.
Once it was build I pressed pebbles into the top to make it more durable. So far it is holding up well. It sits under an overhang so it doesn’t get very wet. I don’t know if it would survive if it got thoroughly wet.
We jokingly call it the Cat Cave. It even has a front porch. The cat loves it. I got him out of it one morning when it was 15 degrees outside and he felt toasty warm. It was free so I love it. I did learn however that I do not want to try a large-scale project like this. It was hard work.
