Bucky was putting weight on all of his legs, but he was moving with some difficulty. He had no visible or obvious wounds or external injuries that I could see, but a bite wound is hard to see unless you can get real close or they lose hair around the injured area.
We've been putting food and water in the storm drain where we first saw him and the food is gone each day. It could be raccoons or other cats eating the food, but Bucky could be eating it if he is still hiding the drain while he heals (hopefully he's healing). We haven't found him anywhere else yet and have looked just about everywhere he could be.
Hang in there, Bucky.
