As they would have stayed with their mother in the wild, the cubs will stay in the rescue center until they are 12-14 months old. Before being released, they will be taught to feed and take care of themselves. Mr. Gray added, warning anyone who may come across an otter that they are "very agile and can have a nasty bite." Apparently, they see people as a threat, and out of fear, may react negatively if someone tries to approach them. The SSPCA, of course, has the means of approaching them safely, so if you come across an otter in need, the best thing to do is to call the professionals.
