In 2019, my beloved cat, Momo, suddenly went missing. Momo was a very sweet and affectionate cat with pristine white fur and bright blue eyes. Every day, he would wait for me at the door when I came home from work, as if he knew how tired I was. However, one day in September, Momo was not in his usual spot. I searched around the house, asked neighbors, and even put up posters around the neighborhood, but there was no sign of him. Losing Momo left a huge void in my heart, as he was not just a pet, but a part of the family.
