Weird things that guinea pigs do!!!

Some guinea pigs do weird things like run around the cage nonstop or or just go crazy and poop on everything. But the weirdest thing that guinea pigs do is.... They eat their own poop. It is very common to see a guinea pig eat their own poop. They do that because their poop contains vitamin c and since guinea pigs cant produce vitamin c themselves they eat their poop to get extra vitamin c. When i first saw my guinea pig eat his poop i thought "What in the world; why is he eating his poop." Well I did my research and found out that they do that cause they know that their poop still contains vitamin c. There are more weird things that guinea pigs do so I am going to list a few more things. Guinea pigs love running around their cages nonstop. I honestly do not know why they do that but for some reason they do. Another thing is  that they popcorn a lot. Popcorn in guinea pig terms is basically, well; you know how popcorn kernels pop in the bag. Well when a guinea pig popcorns  that is basically what they do. They will jump around and make weird sounds.
