Well I made a cat shelter out of a big Styrofoam container you can get at petsmart. Cut a hole in it then clued some mylar to the cover and bottom then put some straw in. Looks real cozy
I would love to see a picture of your shelters. Sounds awesome!I have seen first-hand eartipped cats still spraying. My approach to that is letting it be. It id refreshing to not try to control matters of this nature. Like bird poop...in the end it is no big deal. The smell itself is an awesome rodent repellent! On another note, I have been. Making shelters that offer escape routes without compromising warmth. I make two tote shelters connected with rubber plumbing and venting pipes from lowes. This way the cats can move easily out of danger into other shelter and out. They love it! My colony site has coyote and racoons....also when deciding on insulation make sure to understand R factor labeling.
