A baby rat is called a kitten or a pup. You can use whichever name you prefer, or both interchangeably if you’re as indecisive as me! As a general rule of thumb, a rat is a pup (or kitten) until they have finished weaning. Then their babyhood ends and they’re ready for adult life in a new home! We’ll find out what age they usually reach that point ...
The average rat litter size for wild baby rats is four to eight pups. Healthy, well cared-for pet rats usually have litter sizes at the top end of this range, or even higher. Mother rats have 12 nipples (more than dogs, cats or mice), so they’re well equipped to juggle lots of newborn baby rats! At least you don’t have to worry what to feed pups.
Rats’ ability to procreate and proliferate is legendary. Female rats produce up to 12 litters per year! Plus, these females can begin to bear children as early as when they’re 5 weeks old. Amazingly, rats only need to gestate for 21-23 daysbefore they’re ready to birth 6-12 newborn baby rats. As they get older, breeding does slow down.
On the day they’re born, rat pups are small enough to fit on a teaspoon. Their eyes are tightly sealed, and their ears are stuck flat against the side of their head. Their tail is much shorter relative to their overall body length than that of a full-grown rat. They have baby teeth and whiskers, but no fur or pigment in their skin, so they appear b...
As you can tell, newborn baby rats have a lot of catching up to do before they’re ready to leave their Mom. Unsurprisingly then, the first weeks of life are packed full of big changes. They experience rapid physical development and break-neck learning curves. It’s a fascinating journey from helpless newborn to self-sufficient grown up, so let’s tak...
Pigment starts to accumulate in their skin almost immediately after birth. But it won’t be until day five that they begin to get their first peachy fuzz of hair. And until they’re four or five days old, a rat pup is pretty much immobile. They’re limited to lifting their head and wriggling back back onto their tummy if they find themselves the wrong...
Peek inside a nest of baby rats, and you’re unlikely to be able to tell where one pup ends, and the next begins. This huddling is adorable sight, and it serves an important purpose too. Without fur, baby rats quickly lose heat from their skin when it’s exposed to the air. So by clumping together in a rat pile with their brothers and sisters, they c...
Let’s rejoin our typical rat litter in their second week after being born. Their baby coat of fur is coming along nicely, and they can just about push themselves up to standing. By the end of the week they might even be taking their first steps. But another big change is afoot for them. Around day ten, the outer ear stops being flattened against th...
When they’re born, baby rats’ ear canals are sealed shut. That doesn’t mean they’re completely deaf, but things are definitely muffled. So, once the ear canal opens on day twelve, things start to sound much clearer. Rat pups can make out low frequency sounds first, and then gradually higher frequencies, until eventually they can hear everything bet...
So we know what they can hear, but what sounds are they making themselves? Rat pups use ultrasonic vocalizations from an early age to tell their Mom when they’re cold, hungry, or lonely. These noises — which sound like baby rat squeaking — are way outside of our hearing range. However, they’re easily audible to an adult rat. This is quite an import...
