Odd to see, The Mouse was used as both an Arms Charge and a Branding Logo (in The Middle Ages). They symbolized “Greed” and “Lasciviousness”. They are often confused with a Rat (which actually was seldom used). Coloring of The Mouse was always natural. They are also linked to another similar Charge known as The Dormouse. They are seen around the 14th and 15th Century.
