Since our move, the cats have been sulking. They thought we were coming down for three months and were horrified to discover it was permanent. They miss their screened porch.
So now they have to watch tennis players through the windows or, if they really beg, I'll open the sliding doors so they can peer through the screen at the birds and squirrels in the tree next to the balcony.
They're miffed, but not miffed enough to sleep by themselves at night. Unfortunately.
