Another example of an unusual pet is the Madagascar hissing cockroach. It's pretty big. It's clean and doesn't bite, and it sometimes make a loud noise. Madagascar hissing cockroaches make good pets for children. In Australia and Indonesia, some people have sugar gliders. They are marupials. These animals have a pocket or pouch for their babies. (A kangaroo is another marsupial.) Sugar gliders "fly" from tree to tree.
