Decades ago, I had friends who had a gray hurricane tabby. They named him Stormy. He was a nice cat.
Out cats, Kedi and Maia, were born on the street, but after their rescue, they have spent all their time indoors. They come and sit at the French and sliding glass doors, but they do not charge outside when the doors are opened so that we can enter or leave. They know that the house is their safe place.
Last night, we had a storm. It was just heavy rain – no hail or high winds or lightning. I went outside to sit under the covered back porch to listen to the storm. Susan joined me, and we left the patio door open for the cats. Presently, they joined us and spent perhaps five or ten minutes exploring the vegetated areas under the house eaves and the porch itself. Turn on the sound so that you can hear what they experienced.
