Housebreaking
（重定向自Housebreak）
Housebreaking (US English) or House-training (British English) is the process of training a domesticated animal that lives with its human owners in a house or other residence to excrete (urinate and defecate) outdoors, or in a designated indoor area (e.g. an absorbent pad or a litter box), rather than randomly inside the house. The pet owner's desire is to break the habit of eliminating in the house, hence the term. House-training (a term more commonly used in British English) or sometimes even potty training are common synonyms for housebreaking.
