I think that feels very very true for me and probably for most people as well. I of course grieved mightily when my mom died. Even though it made nearly zero practical difference in my present life at that point. I was grieving the loss of things past, and of the future - I would not see her in the future, and I also greatly grieved that she would no longer be able to do the things that she loved so much in the future. Subtract all that past and all that future, and what's left? I think that's where most animals are at... there is much common ground, and they clearly feel emotions as strongly as we do, but they experience the world so differently.
