As you may remember, Murphy became an indoor cat about 15 months ago because he kept getting seriously injured in fights. It amuses me because neighbourhood cats come by and check up on him. The most common visitor is from next door:

Not Murphy, Smokey
Yep, I know he looks very like Murphy. I have to double check sometimes and Lisa (from the comments) phoned me one time to tell me Murphy had escaped. Seen next to each other (as much as the glass doors allow), you can see there are some subtle differences:

Murphy and Smokey
This photo might show it better:

Murphy and Smokey
Murphy is about a third bigger and has a longer tail; but to be honest, I usually tell them apart by the fact Murphy wears a collar and Smokey does not.
Murphy does not always like having visitors and will run from window to window trying to get at the other cat. Smokey amuses me because he uses my sunny patio for his naps. There are lots of dogs where he lives so it is quiet here. Sometimes when he is napping Murphy doesn’t even notice him and I’ll have two gray napping cats, one on my lap and one just outside the door. No, before any one asks, they are not related. Murphy came with me from St Paul, MN and Smokey, as far as I know, is DE born.
BTW I’ve been waiting ages to get a picture of Smokey and Murphy together. On Saturday, I was taking some pictures of my knitting (patience, patience) when Ol’ Smokey wandered by, giving me a great chance to get these photos.
