Harley's Angels Cat Rescue, Inc. uses volunteers who can house animals in their home that are in need of extra attention.  It may be a fearful shy animal, orphaned kittens or an animal that is pregnant or has just had a litter of kittens.  This assures that the animal will have its physical needs taken care of, and in some cases that requires round the clock care.  It also allows the animal the opportunity to be socialized or to work on behavior modification that might be necessary in order to give them a better chance of being adopted.
