Ours are outdoor 3/4 of the year. But with yesterday’s snow, and now us going into the Deep Freeze for a week, they’ve decided INSIDE is better.
I’ve never seen a mouse in this house in the 10 years I’ve lived here, so they’re doing a good job on that, too.
Not cold by your standards but cold enough and windy. Three in the heated shop, six in the barn in houses or up near the roof under the skylight enjoying the sun after it was so bleak and rainy yesterday. They do not appear unhappy or uncomfortable.
I saw a neat idea to build a sun tunnel with plastic cover and straw bedding like a bow cold frame. I may try that at the garden for them this winter. They love outside in the warm sun.
