Squirrel Fat or Pregnant: The Only Guide You Need!

Squirrels and other rodents don’t get big bellies like humans when they get pregnant. It is quite difficult to tell if a squirrel is pregnant.

A squirrel, maybe a couch potato, or have just taken a heavy meal from your lawn! How can you tell if a squirrel is fat or pregnant? In which season do squirrels get pregnant, and how long the pregnancy of squirrels takes?

The pregnancy of squirrels is short and lasts for only 45 days. At the end of pregnancy, squirrels have clear and large teats, indicating a pregnant squirrel. However, pregnancy can only be confirmed by an experienced veterinarian after palpating the squirrel’s tummy or by using an ultrasound.

How Can You Tell If A Squirrel Is Fat Or Pregnant?


It is difficult to confirm whether the squirrel on your wall is fat or pregnant. However, you can make good speculation by noticing a few details.

First of all, confirm that the squirrel you are looking at is female; otherwise, it’s an old fat male squirrel! Look at the ventral side of the squirrel’s body. Males have large reproductive organs. If the squirrel you notice is female and has large teats, it may be pregnant. 

It would be best if you also considered the breeding season. Squirrels reproduce twice a year, once between December and February and then again between June and August. 

There are pretty good chances that she is pregnant if you can notice the large teats in the breeding season.
