Found this baby (a mouse?) on the road when I was biking.
The mother was crossing the road in front of me and accidentally left her baby in the middle of the street. I picked up the baby and put him/her on the side. I was there for about 10 mins but the mother never came (though I heard her squeaking when I got close to this little one), so I left the site and returned 1/2 hour later, the baby was gone and joint his/her family again.
