How many of you have a class pet and if so what is it? My kids LOVED the butterfly unit and I would love to have a more permanent pet in the room but I want it to be something easy and something that can stay for up to a 3 day weekend without needing to be taken home. I would love a turtle or a frog, but the center for disease control says not for kids under five. Thoughts? We have a really small room. We also tend to have pretty severely behavior/autistic special education students for different parts of the year as "misplacements."
