Mice are part of a new kind of pet known as “pocket pets”. There are many types of mice available as pets. Make sure you do your homework and research the best for you. Coming in a range of color, from white to apricot to spotted, mice are nervous, fidgety animals. Due to this you must always pay attention when holding your mouse. Once they get out of your hands they're apt to run away and hide, making them difficult to find.
