While my wife and I have had many friendly felines (and canines too, we like both) in our family over the decades, I remember especially fondly the cat, Moby, I inherited as a bachelor in graduate school. This cat was a very big, black & white (tuxedo) cat with extra toes on each paw.
He was big, but he was very gentle and damn near as attentive as a dog as well. He would follow me around my apartment everywhere, and whenever I
sat he was immediately on my lap. If I laid down, he would instantly be sprawled out beside me.
Most of the time, when I would smoke my pipe, he did not take any particular notice. HOWEVER, one time, I blew a smoke ring….. and he was extremely intrigued and got up and started to paw at the “ring” trying to capture it as it floated in air.
When I saw that, I tried again, and he again tried to snag the “ring”. It soon became a bit of a common “parlor trick” I would show folks when they would visit. He always brought forth a bunch of smiles and laughs with his “trick”.
