It is a fact universally acknowleged that one of the two main uses for the Internet, a technology which can communicate instantly across the globe, is the sharing of cat photos (the other being starting fights with random strangers). The reason is, I think, more than the fact that moggies tend to be very photogenic…it’s that generally their desicsive moments are less than, well, ‘moments’ and more like descisive hour or twos. Unless of course they are doing something very, very photogenic and you have to go and get a camera, in which case they’ll decide that they need to move just as you set the autofocus point; another reason I suspect for their popularity on Instagram as generally you can grab your phone and get the shot. Which is what I did here, black and white cat, white windowsill: monochrome conversion, who needs it?
