Frankie's House

Frankie has been using his new house for three weeks (more, less). He is very attached to it, having no problems understanding at all that it is his shelter. During the middle of the day, when it is very hot, he takes shelter inside of it. It rained very hard yesterday (the last bits of another hurricane) and the shelter proves to keep him dry. My concern is this: is he spending too much time in it? There was sunshine part of the day today, as the clouds moved away, but Frankie did not come out. I am going to monitor his time inside his house closer.
