Koalas usually produce just a single offspring each pregnancy. Twins are very rare.
You should not disturb the mouse at all. Leave her with her babies and let them bond and get used to each other. After three days, you can then look and pick up the baby mice, but remove the mother mouse from her cage, or she'll start moving the babies around.
ranges from 6 to 10 It can depend. The first litter tends to be smaller, usually 5-8 babies. Each subsequent litter tends to be 6-10. But this does depend on your mouse - one of mine gave birth to her very first litter just today and there are 11 babies! That really is unusual!

A chimpanzee typically gives birth to one baby per pregnancy, although twins can occur on rare occasions. The gestation period for chimpanzees is about 230 to 240 days. After giving birth, a mother usually waits several years before having another baby to ensure proper care and bonding with her offspring.

Babies typically start to move in the womb around 7 to 8 weeks of gestation, but these movements are usually not felt by the mother until about 18 to 25 weeks into the pregnancy. This sensation, often referred to as "quickening," can feel like fluttering or bubbling. Each pregnancy is different, and some mothers may feel movements earlier or later than this range.
