Practice and habit: we called it (in medicine) – the usual order, the way of doing things, how things went in our household. And, of course there were always exceptions in the way our cats went about things. Ray liked to sleep in containers and on the rug in front of the TV. He did not sleep on the loom, until, he did. I find that a lot of the pictures I have of the twins were taken sequentially within moments with one twin here and the other in a different location. Telling which was which was still a trick, sometimes. Nutley? He loved to burrow under the rugs. Yeah, he would nestle right under them, sometimes a mere lump, bump, in the rug. These pics are in my catalog and will always make me smile.
