Though I don’t have any personal experience in this but I think the main pitfall in any project is delays in time. Especially this process of animal testing is time consuming. So in this scenario if the location is 1600km away you should firstly contact more different suppliers in advance s they might get out of stock sometimes. And also I think we should open our studies to more than one animal. We also have to take in account the cost of animal, transportation, maintenance and new location. But yes ofcourse outsourcing in different locations hurts the company as it gets difficult to maintain teamwork, and quality. And most important drawback is compromising on results, time and data.
