Sometimes you already know there is a critter in the classroom. Bobbi had a large brown rabbit in her second-grade room. Bunny had the run of the place, as long as the door was closed. I subbed in there one dark and gloomy winter day, thinking Bunny was resting in her little hutch, as the cage door was closed. The kids are falling on the floor laughing, I am leaning against the desk trying to figure out what happened, and poor Bunny is racing around and around the room like her tail's on fire.
Rats make good classroom pets.
They must, there are so many of them. Rosie was a nice rat, as rats go. She was in a fifth-grade room in Ames, Iowa several years ago. She was pure white except for her beady little red eyes and her icky pink tail. I was an aide in those days, and part of my job was to feed Rosie.
