Piper is a hamster, but I think some petstores drug the animals so they get along with the other animals in there cages or tanks. Because she was so calm in the petstore, but when I got her home it was a different story.
She is such a sweetie now though. The other night my boyfriend got a little upset with her. Because a couple of times he has tried picking her up and she tries to bite him or does bite him. I had to explain to him that he is putting his hand in her cage and she is just being protective in her home and she will bite when in this scenario. After I let her come out of her cage, and he tried to pick her up again and she was fine and did not try to bite him. So he is now willing to give her more of a chance. He is just sensitive, and is so loving and was kind of offended that she tried to bite him, when he is really trying with her.
She is also very awnery. You will be doing the dishes or cleaning something in the kitchen and she will try to trip you with her run about ball, or you will be sweeping something up and she will run through the area you are trying to sweep up. It is kind of funny, because it shows her intelligence, and that she knows she is messing with us and she has a funny sense of humor at the same time.
