I've made six mice of varying sizes from a small to a rather large, but all can be accurately called life sized, depending on the species.
Some kinds of fancy mouse I've read can reach a foot long (with tail).
My longest one here is 8" with the tail.
Interested potential buyers of mice in the state of New Mexico should contact Manitou Galleries of Santa Fe.
Any New Mexico inquiries will be directed there.
