Several days ago, while cleaning out my shed, I found one baby mouse, eyes still closed, but some fur. No signs of mother or other littermates. After waiting hours, I returned to find it still there. I brought it in due to damp, cool weather, placed in a container over a heating pad (low setting) and proceeded to go out to get some kitten formula (which saw recommended after searching for help). The baby was able to eat small amount, using a quality artists paintbrush, but remained lethargic. Later, I was able to administer some pedialyte. Based on pictures seen on-line, appears to be about 9-11 days old. Been feeding every 3-4 hours over last 3 days and been able to help it relieve itself by gently message abdomen/genital area. Eyes remain closed. I just notice that it appears to have a deformed front leg or possibly clubbed foot. Compared to good leg, looks like a small knot at knee (??) joint, and claws of foot turned slightly outward, and toes not as developed as other side. Still able to ambulate, but sometimes falls to that side, getting back up quickly. My hope was to rehabilitate it and once weaned, slowly introduce it back into the wild (starting in the shed where I found it), but now am wondering if that is at all possible? Do you think the leg will heal itself, while most likely a limp? If not, I have read where it is not possible/practical to keep a wild mouse as a pet. Not sure what to do, but certainly want to give the little thing a chance at life, but not risk unnecessary suffering. My vet does not deal with exotics, mice and rescues not interested in mice....implication is just destroy it...I can't do that! Any recommendation/advice is greatly appreciated. Trying to get a good picture of it, emphasizing the bad leg and will post once I can get one....It is so tiny and squirms so much. Thank you.
