I know dogs and cats mourn their dead children, and close companions. So do horses, if they know somebody they loved has died. In most cases, though, animals owned by humans are never allowed to see or smell the bodies of their dead loved ones - all they know is that someone isn`t around anymore.

We have no idea how much other species understand or what they feel about death, because we either don`t pay attention to them or control their circumstances to such an extent that all we can see is how they relate to us.
