Was having a discussion with my friend about small animals. Can they actually be litter trained? After more research i discovered that some actually can be trained and especially if you put the litter box to the side or corner where they mostly relieve themselves. http://www.petstreetmall.com/small-animal-supplies/ The litter box obviously has to be cleaned but the fact that they can actually be trained, i found amazing.
I've seen rabbits that are litter trained.
