Well the story ends well. I spent the morning on the phone searching for someplace that would take us on Friday (and not charge an arm and a leg). I ended up finding a wonderful vet in another county (about an hour away). So I went on a "road trip" to visit the vet and get Mommy spayed. The vet was great, she spayed her, gave her a rabies and distemper shot and treated her for fleas and ear mites. For anyone who lives out in Harford County in Maryland I would definitely recommend this woman. She told me to keep Mommy quite for a couple of hours and them let her go. I did just that and it seems that Mommy is doing just fine. She even ate some of the food I put out for her.
