How long before baby gerbils start to crawl?

Baby gerbils, also called pups, typically start to crawl around around 2 weeks old.

Here's a general timeline of their development:

* 0-1 week: Pups are born blind and deaf, and rely entirely on their mother for warmth and nourishment.

* 1-2 weeks: Eyes open, and they begin to explore their nest.

* 2-3 weeks: Pups start crawling and playing, and their teeth begin to erupt.

* 3-4 weeks: Pups start eating solid food and become more independent.

* 4-5 weeks: Pups are fully weaned and ready to be separated from their mother.

It's important to note that these are general guidelines, and individual pups may develop at slightly different rates.
