Distinguish Between Pregnant Guinea Pig and Fat

Distinguish Between Pregnant Guinea Pig and Fat

It can be hard to distinguish whether an adult female guinea pig is pregnant or getting fat. This is because a female guinea pig will start to gain weight just like a fat guinea pig.

Another thing is that a pregnant guinea pig will increase their food intake during the pregnancy period to nourish the baby inside her.

Some of the ways that you can use to determine if your guinea pig is pregnant are stated below.

A quick way to determine whether it is pregnant is its size. Pregnant guinea pig’s sides usually curve outward and will continue to stretch as the pregnancy continues.

If you cannot see this, you can compare a potentially pregnant female to a female that is not pregnant to see this.

The second thing is to be on the lookout for the way your guinea pig wall or run. You will notice that they walk or run awkwardly to accommodate their new weight. An active female guinea pig may also stop being active once pregnant.

You can also determine if a guinea pig is pregnant by hand feeling it. You are going to feel lumps under your fingers if you use your finger to examine her sides and stomach gently.

However, it is not all pregnant guinea pigs that love to be touched, and if that is the case, you can leave them alone.

Another way to get a definite answer to whether your guinea pig is pregnant or fat is to consult with the vet.
