Pros and Cons of keeping Mice?

i am interested in one mouse, and one only. I would like to know the basics of keeping one and the pros and cons of having one has a pet.


I am purchasing it from a pet store but I'm unable to go in and ask these questions due to lack transportation until next weekPros and Cons of keeping Mice?
as for care it needs to be fed and watered every day. the cage needs to be cleaned about every other day or once every 2 days. you can buy bedding at the pet store. you should also get a toy for it..like a wheel. mice make nice pets (but i like rats myself) pros..they are cute and easy to train..cons..they only live 2-4 years ...and if you start with a male and a female you'll have a huge colony in no time!
