I will answer the cat question first.
I have two lamps with candles in them suspended on either side of the shrine from braces on the wall. You can get them from any Byzantine or Orthodox religious goods store.
I am afraid I don't have a picture. Ever since my wife and I bought our first house, we have been lucky enough to have a room devoted to prayer. The room in my home now is fairly small, as I live by myself. There is a high rectangular table covered with a cloth, and with my mother's large family DRV Bible and two candles I can light when I am actually in the room on top of it. There is also a hand thurible on the table (This is a small thurible with a handle rather than a chain.)
There is a large wooden Latin style crucifix on the wall, with icons of the Sacred and Immaculate Hearts on either side. To the right of the table there is a large statue of St. Joseph, out family patron. On the left there is a statue of St. Michael (my patron) on a shelf, and icons of the patrons of my wife, all our children and their spouses and in-laws, and all the grand children. I am currently searching for an icon of the patriarch Adam for my newly adopted grandson, but I have not found one yet. Fortunately his is taking the name Philip when he is baptized and chrismated tomorrow, after St. Philip Neri. He read a very old children's book about him that for some reason was in our local public library and fell in love with him. I won't have any problem finding an image of St Philip Neri.
There are other icons and statues of the patron saints of other relatives of family friends in the room as well.
