One time my guinea pig was crazy or as to say hyper. Ok. So when he was running in my room at night (cause they need good exctersize). he was really fast. I mean if I entered him in a race he would surely win.  So first I started putting on my clothes and brushed my teeth and he was still running. Dom't worry I was keeping an eye on him So anyway all of a sudden he burst into speed. He never stopped running. Also now since I finished brushing my teeth and dress up for my bedtime, I kinda started chasing him but I didnt walk. I kinda crawled. So he was running super fast and away from me so I tried him some grass. So when he heard the sound, he stopped running and he like froze. Then he slowly crept to his cage and then he went inside. FINALLY HE WAS INSIDE! So then everything was in controll and I could sleep untill it was time to wake up.
