are the cats fixed?

All of the inside ones are fixed, but the outside ones aren't.
But since the outside cats have four feet, I think this
characteristic outweighs the fact that they are un-fixed;
so I employ four-footed fixed lines for them as well.
(Though there is one [her name's Bastet] who has only
three legs; her lines, of course, are trimetric ones.)

There is a difference, by the way, between the outside
cats' lines and the inside ones: The inside cats' lines
are, obviously, catalectic.
