Some Central Valley groups that provide care for injured or orphaned wildlife:
Sacramento County: Sacramento Wildlife Care Association, 916-965-9453
Note: Wildlife Care Assoc is open 7 days a week from 10 to 6 pm and injured/sick birds and wildlife (except bats) can be brought there for medical care. It is located at 5211 Patrol Rd on the old McClellan Airbase. From I80 go north on Raley Blvd. At Bell Ave, turn right. Go .7 miles on Bell and then turn left on Parker (difficult to see but at the start of a long chain link fence). At the stop sign go right on Dean. Turn left on Patrol Road. The facility looks like a giant golf ball and is easy to see.
For injured/sick animals after 6 pm and for orphaned birds and mammals, it is best to leave a message on the hot line number above. NO PICK UP SERVICE.
To catch animals, try throwing a towel over or use a pool net. Use heavy gloves when trying to handle a raptor or adult mammal. Keep animal in a dark, quiet and warm location. Birds caught by cats should always be brought in within 24 hours even if they seem uninjured. Cat bites can lead to fatal infection.
