when my cat passed away after being hit by a car. it was just after my hockey practice.
who knows. they could have been like my mom, and maybe they were different and were too ashamed to say anything. might not have noticed, either. or they were just bad people. hopefully you can focus on your pet and how much you loved them instead of those things you cannot get answers to.
it was so difficult, i do not even know if the person cares that they took away my favorite pet.
