Roof rats are what we have around here. There's three subspecies of the Black Rat; black, grey and brown and we have the grey subspecies. The subspecies name of the grey subspecies is
"frugivorous" and they really do show up in numbers if you have orange trees.
They go through boom and bust cycles on my side of town and true to the name, really do go up high in buildings and houses, you hear 'em up in the roof.
One time, years ago I was teaching class and I saw a roof rat in the back corner, against the wall, the kids hadn't seen it yet. I kept on teaching.
Then the rat walks up to the front corner of the classroom against the wall, kids still ain't noticed, I kept on teaching.
There was a meter stick leaning up against the chalk ledge at the bottom of the board (ha! chalk! Thats how long ago this was.) As I stopped and watched the rat walks up to the meter stick, climbs it,and proceeds to walk across the chalk ledge in front of the blackboard.
I look at the kids and they are all tense and wild-eyed, like nervous horses about to panic. One trigger from me and it'd have been chaos. I look down at the rat as it passes and said
"Henry, I told you never to come here when I'm teaching.".
At the other side of the board was the electric chord that went up to the TV mounted at the ceiling. The rat went up the chord, climbed the TV and the mount, and disappeared through a small opening they had chewed in the ceiling tile next to the TV mount.
Then I went on teaching, and the kids went back to work. Might be my finest moment ever as a teacher. I set snap traps that night and caught two.
Teaching the classroom next door was a cranky, heavyset lady who caused me no end of problems. A few weeks later I hear pandemonium from her classroom, and a high keening like from a predator call....
"EEEEEEEEEE!!!....... EEEEEEEEEEE!!!!!!!"
I go over and there's that teacher lady screaming and standing on a chair....
To indicate just how long that was ago, I'm currently teaching a kid of a couple of the kids who were in that classroom that day, they still remember the rat too.
