What is universe 25?

It was an experiment with too many mice, too well cared for. The mice became withdrawn and… “Though physically able to reproduce, the mice had lost the social skills required to mate.”
That guy’s experiments were the inspiration for the Rats of NIMH books, which led to The Secret of NIMH movie!
Now I want to see human population density compared to birthrate 25 years later for regions with a current sub-replacement birthrate.
“Losing the social skills required to mate” sounds like many people I know.
It’s an experiment that was conducted to see what would happen when mice were given what people supposed would be a mice utopia. Things did not go well.
Here’s some videos, pick your poison lol
That’s not Utopia, that’s rats in a bag: overcrowding.
Animals need more than food, water, a clean environment, nesting material, stable temperature and freedom from predators.
All life forms need space to live.
My brain really wants to see loss in this…
Universe 25?
I’m just gonna paste from a different comment:

Oh my bad I totally thought it was rats, I’ll edit my comments accordingly
Despite all my rage, I’m still just a rat in a cage
