This is also true of rats. Our eldest is just beginning to come out of a major depression brought on by the death of her sister. She's been in mourning since January and she'll most likely never be the same again - she even cries in her sleep. One of our old girls passed away just after Christmas and her twin sister went into a state of shock and passed away the same evening. She couldn't cope with the loss.

Awww, poor little broken hearts.

And crying in her sleep?! She sheds tears, or is it a mournful sound she's making that makes you think that? Because that's truly a sad little picture.
Rats are some of the most amazing care givers, in a communal family atmosphere. I use to visit a pet store , when a friend was considering a exotic bird purchase. While she shopped, I watched the rat collections in the back. Feeder rats, sadly enough.

When they had their pups, (hope that's the word for baby ratling.) , the mother would be attended by every other rat in the pen. And when a customer would come to purchase one, for a snake dinner, the others would cluster around mom and babies, so the hand reaching in wouldn't come near them. I remember thinking of that line in the Star Trek movie, where Spock dies. The needs of the many outweigh the need of the one.
I think humanity could learn a lot from watching the social chemistry in rats and all the animal kingdom. Dumb animals, as a term, is an insult to those that use it to describe a single one. I dare say I couldn't build a house from scratch with what I know now. But watch a bird build a nest, and it's truly humbling how little we know, left to our own nature, without the education as to how to survive. While wasps can weave a paper nest that reminds me of what a 10 story condo complex would look like, as it's suspended from the boughs of a tree. I found one of those once. Long abandoned, I cut it open and looked inside. Then I realized how lucky I was to afford to buy a house, someone already put together.

I hope your rats feel better after such tragic losses.
