Bugs & Bunny

This is my daughter's lil pets, Bugs and Bunny. Not too sure which one is Bugs and which one is Bunny, but I guess Bugs must be the dark grey bigger one and the other must be Bunny. They eat all day long and is getting bigger and bigger by the day. Funnily enough, my daughter does not dare hold them, so its my driver that does the cleaning up most of the time. Soon, this cage will not fit the two bunnies. Wonder if it will run away if we let it play in the lawn around the house...maybe not.
