I had Abby done on a Friday so that I was home for the next couple of days with her. Most places keep them overnight but this place said I could get her at the end of the day. Check friendsofanimals.org. Not sure if it is only local to Connecticut, but you can purchase a spay certificate online for $90. Then you find a participating vet. The only things you get charged for are then things like pain meds. Our vet had said the normal fee was like $350. So this was a good savings.
Definitely bring home pain meds, specially if she is coming home the same day. Find out about dosages, etc. Ask about how to check the area, what to watch for, oozing, etc. Abby had a very small amount of fluid that evening that was discharged but it was clear and clean and no more came. I kept her on nice soft towels for the next couple days and gave her lots of loving and naptimes. She was a little groggy until half way through the next day. When I brought her home, she actually kept trying to go into the garage rather than the house. I think she was confused. She had only been with us for 2 weeks at that point also, so she was not entierly familiar with the area yet. Make sure she drinks, etc. Typically, they can be a little too sleepy to bother drinking much or eating. Don't worry about the eating so much, but do make sure she drinks. I believe we were told not to feed her until the next morning.
