One thing which may or may not have previously been mentioned. That is, the different sensing abilities of various animals. For example it has been said that sometimes pets such as dogs and cats may react with either affection or aversion towards something unseen, a bit like a related phenomenon of humans approaching their own death seeing or having conversations with unseen (to anyone else) visitors (and perhaps occasionally some less welcome and frightening visitation). I've long considered that even ordinary human-to-human communication, such as a face-to-face conversation, takes place in parallel with a telepathic sharing of thoughts or emotions. When people say of their dog or other animal, "he/she understands every word I say", perhaps that is true, not due to a grasp by the animal of English grammar and sentence construction, but due to an associated telepathic link.
In the case of animals, I'm thinking perhaps of elephants but not limited to just those, when they gather in groups, we cannot tell what sort of mind-to-mind contact is going on. And in the case of the death of one of the group, there may sometimes/often/rarely be communication with the deceased. What we do know is many animals grieve and suffer after the loss of a fellow.
Even humans do sometimes behave oddly, such as retaining the corpse of the deceased for decades, perhaps in order to continue to claim a pension on their behalf, or other unconventional reasons. But we don't see this as meaning humans don't recognise death.
