This is so cool! (feral cats)Architects For Animals
From their 'about' page:
Some of the shelters can be seen on their page, and there is a link that shows you how to do your own. How cool is that?
Unfortunately for people, kitty shelters are far less expensive to construct. I've built several for local ferals for about five bucks a pop. It would be wonderful to have nobody homeless, but I do what I can.
The shelters pictured looked pretty involved, except for the one made from tubes. That one seemed really practical, easy to make, and would also be recycling.
Anyhow, on behalf of the feral cats, I thank you!
