No wonder Madeline is in such good shape 😅 She does this for hours every night! In the wild, mice run an average of 1-2 miles per night - although not in a straight line. Most of them have small territories and travel less than 500 feet from the nest where they were born. The longest lifespan for a deer mouse in captivity is 8 years, but average is about 4 years. They're fascinating creatures when you do a little research 🤓 #themoreyouknow #deermouse #petmouse #miceofinstagram #miceoffacebook

Madeline and Harriet 🥰 Madeline is about 2/3 the size of Harriet and still has her grayish baby-fur. She will gradually change to a Fawn color (which is where Deer Mice get their name) as she ages. The two seem to love being together, and while Madeline doesn't want me to hold her, she will come and climb on my hand to take some treats when I reach into the cage. #harrietmouse #madelinemouse #deermouse #petmouse #miceofinstagram #miceoffacebook #micearenice #miceofinsta #tinycreatures #cuteanim
