"...well taken care of and healthy..."

When it comes to an animal that is entirely dependent on our actions for its well-being, it is critical for us to ensure that its needs are being met by any means available to us. As those needs change, we must be able to recognize this and respond accordingly. If we do not do so, it is a very real possibility that its quality of life will be negatively impacted. It doesn't get any more bottom line than that.
