I had a lot of common questions/concerns after my girls' spay (licking at the incision, not eating, how to check the incisions, etc.) that are discussed in the above thread.
first aid supplies I recommend stocking up on prior to a spay (I put all of them to use with my girls):
~ critical care food (can be bought online, at some feed stores or through vets)... get apple/banana as a lot of bunnies loathe the anise
~ pedialyte, preferably unflavored (in case she's not drinking much)
~ vet wrap (in case she's bothering the incision site)
~ bene-bac or another probiotic (probiotics should be given before and after any surgery; also any time an antibiotic is being given and any time an animal is under stress)
~ fruit flavored baby food
~ any favorite treats she has... banana is super popular with a lot of bunnies and helped entice mine into eating on their own again
