Most mouse characters actually bug me and here are my reasons. I personally think that mice should be small. This would have two ranges... action figure size mice standing at about four to eight inches tall, or the most human size mice ought to be about four feet tall. Also breast size of the females shouldn't be overly huge. Ever heard of Itty bitty mousie titties? Male mice on the other paw can have a decent size penis for thier size, since ounce for ounce... yeah, they can get sizable. This doesn't mean though that a four feet tall mouse would beat a horse in a direct sizing contest, but he could easily reach seven or eight inches. Strength is debatable,

Exceptions to this rule: mice made in a lab can break all the rules. They can be tall and busty.. even uberbusty. Her unique situation is explained. Since there are so many tall mice running about I find it hard to turn them down, but I will make a comment about it.
