As a small creature, the hamster is more fragile and needs to handle with more caution. There is a high chance that the hamster would bite you. 

To prevent such events, a guinea pig is more likely to have as a pet than a freaking hamster.

Because a long-lived creature means a long-life commitment. 

Basically, a guinea pig lives for 4 to 8 years. On the other hand, a hamster can expect a lifespan of around 1 to 3 years. 

The lifespan means a lot. A longer lifespan for a pet creates a great bonding between the owner and the pet. In this regard, a guinea is far ahead of the hamster.

But the hamster-like to live solitarily rather than being friendly like the guinea pig. 

Noise Creation

As a friendly creature, the guinea pig creates different and a lot of sounds. They are noisy and love to generate sounds. 

On the other hand, the hamsters are not that noisy. They just let you know their presence in the morning by creating soft sounds in their cages. 

Space Needed to Pet Them

Since the guinea pigs are comparatively bigger, they need a bigger space as well for living and playing. In the long run, they are suited to the outdoor. 

Opposingly, being small creatures, hamsters are suited to indoor living along with smaller cages comparatively. 

By the way, both animals must have cared for the proper spacing they need. 

Care They Need

Are hamsters or guinea pigs easier to take care of? As we have seen yet more legit reasons to pet the guinea pigs, both pets need special care to be taken. 

The owner must help the guinea pigs to synthesize Vitamin C externally for the guinea pigs as they cannot do it themselves. You also need to provide them with sufficient fibered food and feed them multiple times daily. 

You also need to frequently clean the bedding of the guinea pigs as they can spread allergies or asthma. 

Both are prone to cancer which must be treated with extreme care, also with expenses.
