Mary Cummins of Animal Advocates and Leslie Rink of the Opossum Society present an important educational show about springtime wildlife babies including a baby and a juvenile opossum. About the end of January to March and then again around July, tree squirrels will have from 2 to 5 babies. Opossums will have a litter of about 8 to 11 babies. Around April and May skunks will have up to six babies in a litter.
