This month-old North American river otter pup is being hand-reared by animal care staff at the Brookfield Zoo in Illinois after they determined that his mom, Charlotte, was not able to provide him with the proper nourishment he needed.Sondra Katzen from the Brookfield Zoo told us the pup will most likely be re-introduced back with mom Charlotte and his dad, Benny, once he is weaned, in about a month's time.(Lynette Kleisner, Chicago Zoological Society/Clipzilla)
