We don't have a cat because Boz, as gentle as he is, is intolerant of the feline set. But I love cats.
My experience photographing dogs is limited mainly to Boz and his pal Sprocket, both of whom are shy - Omega dogs, if you will. They're photogenic but not great at close-ups because they don't like to challenge the camera.
Cats are indifferent to the camera. Look at it, don't look at it, whatever. I have a nap to take, a bug to annoy, a glorious body to lick.
This photo was one fun result of an ill-fated tea outing with friends in August (other fun results were good company and Miss Havisham's post).
