Pups are born blind and hairless, and they rely entirely on their mother for warmth, food, and care. They start to develop fur and open their eyes after about two weeks.
Here are some additional facts about baby rats:
* Litter size: Rat litters can range from 4 to 22 pups.
* Weaning: Pups are usually weaned from their mother around 3-4 weeks old.
* Growth: Baby rats grow quickly, reaching adulthood at around 3 months old.
It's important to remember that rats are intelligent and social animals, and baby rats are especially vulnerable. If you find a baby rat, it's best to contact a local animal rescue or wildlife rehabilitation center for help.
