2. Guinea Pigs...

Guinea pigs are popular classroom pets and for good reason.

These small mammals are friendly, easily tamed and generally fairly low maintenance.

They require an appropriately sized cage and time spent out of their cage every day, but they are neither messy nor expensive.

They can also bond with their owners and provide much of the same affection that children receive from dogs and cats.
