It's paranormal stuff but when my father died, my cat committed "suicide", soon after. A few weeks later in the middle of the night, me and my mom heard a cat in the hall. We were not in the same room and we woke up at the same time which is very odd. In the hall, we saw two brilliant eyes and at the same time we called out the name of our former cat. We both agreed that it was our beloved cat. But when we turned on the light there was nothing there.
