The number one answer to this question is, “Leave it alone!” Many wild animals, especially rabbits and deer, leave their young for extended periods of time, so we should not interfere with them.
If you truly believe a wild animal is in need of assistance call the Missouri Department of Conservation (see link below) or the Lakeside Nature Center at 816-513-8960 for advice or visit their webpage at lakesidenaturecenter.org. Local Missouri Department of Conservation Contact»
