Mice are amazing pets. They're cute, fluffy, intelligent, inexpensive, and pretty easy to care for. They're great pets for people with limited space/time, or who don't want a decade-long commitment, but still want to have a fluffy companion. 

In spite of these positives, it is important to remember that EVERY living creature takes time, effort, money and work to care for. Mice require cage cleaning, fresh water, food, social interaction, toys, and medical care like any other pet. Below, I will go over all of the care you can expect to give your pet mouse, and what I as a breeder expect of pet owners who adopt from me. Please remember that every breeder and owner does it different, and these below are general guidelines that should work well, But that doesn't mean it's the only way to do it right!

There are many different types of enclosures that will work for mice, including glass tanks, bin cages or other DIY options. I do not recommend a wire cage for mice, as they are difficult to clean, drafty, and make escaping easier for your mouse. 

instead, opt for a closed tank that isn't too tall (around a foot-18 inches is good), with good ventilation, and holes no bigger than 1/4 inch.  Your cage does not need to be massive, but it also shouldn't be so small you can't fit anything in it, either. i generally recommend a 20 gallon (long) glass tank, or a 64qt bin cage as the minimum size for pet owners. This size will allow you to fit all the necessities and a few extra fun things, without being sooo big that you struggle to decorate it all and make it properly cluttered. Mice LOVE clutter. The more cluttered your cage, the better.
