She will most likely be a little lethargic and depressed afterwards, however one of my females was right back to normal immediately. I would ask the vet for some Metacam to bring home to continue for the next few days after the spay to help reduce pain. Have a variety of fragrant vegetables on hand to help entice her to eat as soon as possible after the spay. Don’t let her jump up on things or move much for the few three to four days. She will need to be confined to a small area to limit movement. Too much activity (jumping and such) can tear the incision open. Watch for her to gnaw or yank on the stitches. Our vet supplied up with a cloth e-collar to use just in case. However, I would only use this if you don’t have a choice as it can be very stressful for them. However, in some instances you have no choice (one of my girls was eating the skin around her incision so we had to put one on her for a few days).
BE SURE your vet does not tell you to fast your bun. Rabbits can eat up until their surgery. I would bring some hay along to put in her area so they can give it to her directly after to help encourage her to eat ASAP as well. Rabbits heal relatively fast so if she’s eating something within 24 hours and her incision looks clean and healthy then you’ll know you’re *most likely* out of the clear!
Good luck to you and your girl!
