We once had a mouse named Sleepy, who had a lot of babies. They didn’t want to be weaned. Instead, they would chase her around until they caught her, then all try to nurse at once: and wound up lifting her off the floor of the aquarium. Her only recourse was to climb up to the top of the water bottle, where they couldn’t get her, and chatter crossly at them.
The mommy critters in this video all had an easier time than that.
