A smart pet-crate is disclosed. The smart pet-crate provides a den-like habitat for an animal and is configured with electronics that include sensors to detect aspects of the animal's environment and environmental conditioners to adjust the environment within the pet crate in response to the detected aspects. The conditioned environment within the pet crate will provide comfort to the animal, which may help to reduce the animal's fear/anxiety. The smart pet-crate may be communicatively coupled to a body sensor worn by the animal and a computing device used by a human to form a pet care system, allowing for remote control of the pet crate and interaction with the animal. For the particular embodiment of a smart music playing pet crate, a method for selecting songs from a playlist based on sensing and computing the animal's preferences is also disclosed.
