(Portland, OR) -- A rescued otter pup is staying at the Oregon Zoo for the summer. Zoo officials say the pup was found abandoned by its mother near Deer Island last month. The pup was taken to Portland Audubon's wildlife center and then the Wildlife Center of the North Coast for rehabilitation. Oregon Department of Fish and Wildlife says the pup is not able to be released, because it's spent too much time with people. It'll stay at the Oregon Zoo with the other otters until a permanent home is found.
