Avoid direct contact, use thick gloves and blankets to contain. Wash hands throughly and all materials used to contain the animal should be washed and bleached or disposed of.
Young raccoons can be quite vocal even when being cared for, though if they are heard crying constantly this may mean the mother is not returning. Babies can be left from the time they are found, overnight until the next morning to give mom time to collect them. Secure them in a container that mom can tip or gain access to. If they are still there in the morning they will need rehabilitative care. Contact an Authorized Wildlife Custodian equipped to accept raccoons.
