What Does A Baby Rat Look Like? Let’s Break It Down.


The first thing you will notice about a baby rats is that their heads are much larger than the rest of their bodies.

What does a baby rat look like when compared with a mouse:

This is a key difference between baby mice v baby rats. The baby rat will have an abnormally large head compared with the rest of the body. A baby mouse will have a normal size head when compared with its body.

When the baby rat is born, it doesn’t have any whiskers, but these grow within the first few days.


A baby rat’s tail is present at birth. It is pink and short.


When they are born, baby rats are bald. This changes around the 7-day stage, when the body has gone through a change in pigmentation from pink. Fuzz begins to develop.

From day 7 through day 14, the rat babies will go through a rapid change and look much more like rats!


The rat’s eyes remain shut until around day 14/15.

The eyelids are very thin, so they can pick up changes in light. This has been tested before by me. If baby rats and in a dark environment, they will turn to any light source (they always look up at my flashlight!), so they know I am there!


Baby rats will huddle together, and they do this for 2 good reasons:

  1. To keep body temperature high enough without moving too much
  2. Easier access for all to the food supply (mom rat)

It is normal to see baby rats huddling together unless they have started to play fight! Then they will huddle when sleeping or feeding.


I know this post answers the ‘what does a baby rat look like?’ question, but it is also essential to know what they sound like.

Firstly, baby rats make a sound, but this noise is usually too high-pitched for regular folks to hear! It is way beyond the ability of our ears.

Having said that you may notice a few squeaks from the baby rats. They use this squeaking to communicate with their mom.

It is worth noting that a baby rat is born with closed ear canals. These usually open at around the day 12 stage. They still react to loud noise, though, from experience!

Mother rat might hiss at you if you get too close, and she feels you are threatening her brood.

Can Baby Rats See?

Baby rats cannot see until around the 2-week stage, as this is when their eyes will open for the first time.

Before the eyes open, the baby rats can see changes in the light behind their thin eyelids. I know this because whenever I shine a flashlight on a nest of rats, they all look towards the flashlight!

When Do Baby Rats Open their Eyes?

Baby rats will open their eyes at around 14 days; before then, they are covered by a fragile layer of skin.

When their eyes open, they will begin to explore their surroundings more than they did before. This is when the baby rats become much more playful and spend many of their waking hours play-fighting with their siblings.

Frequently Asked Questions

Cows milk does not give baby rats what they need. Instead, you should be using specially formulated milk. I suggest using milk specifically designed to feed baby kittens. This is used regularly and successfully when raising orphaned baby rats.

Baby rats survive on their mother’s milk for at least 4 weeks; however, when they reach around 14 days, they will begin to eat other foods, similar to what adult rats eat.

It is worth remembering that rats carry several diseases they can transmit to humans. Just because you found a nest of cute rats doesn’t mean you should not be concerned.

If you have found a rat’s nest, you will want to get rid of them quickly. They will not be a young rats for long!

They will be old enough to reproduce before long, and you will have a house full of rats in no time! Rats have tons of babies, and they replicate at an alarming rate.

So, good luck!
