Pets are no more just a pet but a part of members of family. They can communicate with face or body sometimes shaking tails or making voice of their own languages.
But they grow old and get sick as well…, and come to the end. They get old 4 times faster than humans’ one. We can’t but accept their happy ending. It’s sad but it’s also knowing how to live and how to die from them. Especially for the young children they should learn how precious life is and taking care of tiny life.
