I recently got 2 guinea pigs as a classroom pet. Unfortunately I was not aware that both were pregnant. I now have 4 guinea pig babies to find a home for. I do not intend to let my students take the guinea pigs home over the weekend or holidays, as I would be devestated if something happened to one of them. Other teachers may be interested in adopting one of the babies once they're old enough, but they plan to let their students take them home on weekends and holidays. Has anyone done this? Did the students take care of the pet? Did you ever experience problems? What age were the students you allowed to take the pets home? Thanks!
