Anytime you have a conversation with someone about if they have any pets the usual response is that they have a cat or a dog or maybe a fish. Although guinea pigs aren't uncommon or exotic animals they are not usually the first pet type that will come to mind. Here's why guinea pigs are actually super awesome.
They make all sorts of noises
Now I know what you're thinking "geez why would I want a pet that make a bunch of different noises?" Guinea pigs make a variety of sounds three of which are...
Squeaking or Talking... This is their idle noise. They make it when they're content and exploring a familiar environment.
Wheeking
This is their super excited noise. You will mainly hear them make this around feeding time. Sometimes they make it just from hearing the fridge open.
Purring
The meaning of this sound is debatable. I personally believe that they make this when they are being pet just the right way, other people think that this noise is only made when they are annoyed.
They get themselves into funny situations
I mean c'mon don't try to tell me that this isn't cute.
They're super snuggly
There's nothing that your pig would rather do in the evening than lay on your lap wrapped in a blanket. It's seriously the cutest thing ever.
You can dress them up
Princess Piggy strikes again!
There are things that you need to consider before adopting a guinea pig. Firstly, they poop a ton. I'm not joking when I say that, you can clean their living area as much as you want and it'll be covered with poop within an hour. You can try potty training them but it really only works if they are in a large area. Secondly they eat a ton. The most money that you will spend on them is food. They require a healthy diet of veggies, hay, water and pellets every day to sustain them. Thirdly you should always get them in at least pairs. Guinea pigs prefer to be with other guinea pigs, just like humans if they are by themselves for too long they get lonely. Finally you need to really put in the time and effort to make sure that they're happy. For example keep them in the proper conditions and don't do anything purposely to stress them out.
If you're not ready to commit to a pet the size of a dog or even a cat I would say that a guinea pig is the way to go. Do your research to determine what type would be best for you and make sure you understand all of the things that need to be bought before bringing them home. Finally enjoy their cute little company! They are truly lovable creatures if you give them the right environment to be so.
