Keep people and pets inside. Staggering, circling or acting unafraid can mean illness. Don't try to trap or touch it. animal control or your local health department.
Pets and wildlife.
Bring pets in at night. Keep pets' rabies shots up to date. your vet if your pet tangles with a wild animal.

Babies found alone.
Leave them be and watch from a distance for a day. Baby animals alone are often just waiting for a parent. Call a wildlife rehabilitator. Hurt or clearly orphaned?
