Pet carrier
Pet carriers are small portable boxes, crates, or cages used to transport small animals such as cats, lap dogs, miniature pigs, ferrets, chickens, guinea pigs, and so on, from one location to another. The two main types are the front openers (these are generally tough plastic boxes with a metal door, such as dog crates) and top openers (these are generally more like cages with a hinged roof), although there are other types.
