I've always just walked in to the Mansell location and was helped in a timely manner
As Tim said; the Mansell campus is pretty much just walk-ins. You're free to go inside the open cat area, the dog kennels, and the enclosed cat room. There are people there to help, just be patient as they help others. It can get very hectic on busy days and a visit that should only take 30 minutes can easily take up to 2 hours, so don't go when you have a tight schedule. I hope all that helps!
