Missy, there is a large breeder in our area and he puts a cat inside each coop/run every single night and he said his rodent problem was a thing of the past. His runs were covered and the cats went inside night willingly. I found it very interesting. My cats go inside the coop during the daytime and sit waiting for mice but they could get out anytime they wanted to. My set up isn't as secure as his is. I was fascinated by his set up.
