Glenn, The SPCA in Montgomery county has a list of Vets that you can take your cat to for the price of the voucher you get at there. (thats how I got Aishya spayed) Baltimore county should also. The SPCA might also be able to tell you a Vet or Vet school that will do it for free. (wondering if UofM has a Vet school) You said the cat has a collar. (I think) It might have its shots and be spayed all ready. Most feral cats don't act like the one you are describing except when Mama Kitty was a house cat.
