The General Characteristics of Guinea Pigs

Let’s figure out what makes guinea pigs amazing pets in the first place. There are quite a lot of various guinea pig breeds. But no matter which one you are going to choose, all of them share some basic traits.

Generally, guinea pigs are friendly animals that have a great attitude towards people. They are gentle and in most cases curious and playful. Keep in mind that guinea pigs have strong personalities and you will be able to vividly see the difference if you decide to adopt more than one guinea pig.

Which Guinea Pig Gender Is Better

Male guinea pigs are called ‘boars’ and the females are ‘sows.’ A guinea pig of any gender will surely make a great pet, but your choice should certainly depend on the aims that you’re pursuing.

In case you want to be able to breed guinea pigs in the future, it might be a great idea to get a male at first. You will then have as much time as you need to pick the perfect sow.

If you initially pick a female, you will only have a couple of months to organize the whole process. The breeding of guinea pigs should ideally take place when the female is between four and six months old.

If you are simply looking for a wonderful and docile pet for you or for your kids, then any guinea pig gender is good. Just make sure to handle the animal a little bit before adopting it. Moreover, the guinea pig should not bite and be overall aggressive. It might take you only a few minutes to assess the temperament of the guinea pig.

The Pros & Cons of Boars – Male Guinea Pig

Male Guinea Pig

Pros of Owning a Male Guinea Pig

1. Male Guinea Pigs Are Less Shy

Each guinea pig is different and guinea pigs are the type of animals that have strong personalities. In general, males are a bit more outgoing and they can show their natural curiosity from day one.

Essentially, it might be easier and quicker to establish a connection with a male guinea pig rather than a female one. Though, you should always remember that there are exceptions.

2. Male Guinea Pigs Live Longer Than Sows

If you take good care of your beloved pet, the guinea pig can usually live between 4 to 8 years, unlike the other rodents that rarely pass the line of three years. However, male guinea pigs tend to live a bit longer than females.

It is important to mention that the lifespan firstly depends on a healthy diet and the overall health of the animal.

3. With a Male Guinea Pig, You Don’t Need to Rush With Breeding

If at one point, you decide that you want to try and mate your guinea pig with another one, it might be better to choose a male guinea pig. Then, later adopt a female when you decide that you want to have more of them.

The age of the male guinea pig does not really matter when we talk about breeding. Female guinea pigs have a certain period where they can safely have babies.

After that period is over, any pregnancy can result in serious health problems.

Cons of Owning a Male Guinea Pig

1. The Males Are More Aggressive

This is the main difference between the genders. The males tend to be more aggressive, especially, when it comes to defending their territory. However, if you’re planning to keep one guinea pig, then there shouldn’t be any problems.

But if you are thinking of introducing a new guinea pig, then a little clash of opinions might occur.

2. Male Guinea Pigs Are a Little Messier Than Females

There is something that you may not even notice if you never had a guinea pig before. Boars tend to be a bit messier and do not care about their house a lot. This simply means that you would need to spend more time cleaning the cage.

The Pros & Cons of Sows – Female Guinea Pig

Female Guinea Pig

Pros of Owning a Female Guinea Pig

1. Highly Social

This one can simultaneously be both a pro and a con. Female guinea pigs adore being surrounded by other cavies. However, they might become very sad if left alone in their cage.

If you want to have at least a couple of guinea pigs, then it’s better to choose females as they won’t get into fights. Moreover, they will become real friends.

2. Generally, Female Guinea Pigs Are Neater

Sows are real girls that like to keep their houses nice and clean. There certainly can be exceptions, but overall, the cage will stay neater if you have female guinea pigs.

Cons of Owning a Female Guinea Pig

Sows Are Shy Around Humans

When it comes to interaction with humans, female guinea pigs are shy and can even get scared while the males are a bit more outgoing. It might take you a couple of months to establish a connection with your beloved sow.

Don’t worry if the female guinea pig won’t let you handle her for quite a while. The sow simply needs a lot of time to get used to you.

What Gender of Guinea Pig Is Better if You Want to Adopt More Than One?

Adopt More Than One guinea pig

If you are going to adopt only one guinea pig, then it’s better to adopt a male guinea pig. Now, if you want two or even more guinea pigs, then you have three different options to choose from:

1. Two or More Females

Female guinea pigs get along extremely well together. In fact, it is always better to get two sows from the very beginning as they don’t like to be left alone in the cage.

Moreover, it doesn’t matter whether the guinea pigs have been together from birth or not. The female guinea pigs are gentle and friendly.

But, remember to give an equal amount of attention and food to both of the sows.

2. Two or More Males

Even though male guinea pigs are more aggressive than females, it does not necessarily mean that they will be constantly fighting. In fact, if the boys were together since birth, there shouldn’t be any major problems.

However, some conflicts might arise when it comes to defending one’s territory.

3. One of Each Gender

A male and a female guinea pig will, most certainly, have a lovely relationship. Have in mind that if there are two males and a female, conflicts might arise.

One extremely important thing that you have to remember is that the two guinea pigs will, most definitely, have babies. It might get dangerous if the female is over one year old and has never given birth before.

Around this time, the bones of the female have already hardened. That means that the poor thing might end up being in a lot of pain when attempting to deliver babies.

If you end up getting a male and a female, you will certainly have a lot of fun observing their relationship.

Certainly, both genders have their pros and cons. Make sure you know the main reason why you need to adopt the guinea pig in the first place.

If you think that one pet will be more than enough, then a lot of guinea pig owners suggest getting a male guinea pig.

Always remember that the females are social animals that can literally die of solitude. So, it’s a great idea to buy female guinea pigs in pairs.

If you want to become a real guinea pig parent and see your beloved pets give birth to guinea pigs, then getting both a young female and a male is a perfect choice for you.

No matter what gender you decide to choose in the end, any guinea pig makes for an amazing pet. Each with a unique personality and taste. You will have a lot of fun getting to know your new family member! Best of luck!
