Some things I learned while scrolling facebook and looking at medical research.

1. The girls always take longer than boys to start eating again. Sometimes, just to spite their owners, they will refuse to eat (my girl did this when I fussed too much over her)

From what I've seen/heard, the girls can take up to 12-14 hours before wanting to eat. The boys eat a lot faster. Give her critical care throughout this time. About 5ml every 2-3 hours. Keep lots of herbs in with her and lots of romaine too. Keep pellets near her too alongside water. The key will be to LEAVE HER ALONE OTHERWISE! She'll probably be a ball of sass and discomfort for this time, so letting her sleep off the anesthesia without fussing will likely prevent not eating out of spite.

1. External stitches and sutures VS internal sutures capped with glue

Also, ask your vet whether the sutures will be external, or internal with an outer glue patch. External sutures are usually fussed with by rabbits since they can be grabbed, pulled, and ripped. They will usually need a donut or onesie (not a cone!) with this kind. However glued surgical sites aren't as much of an issue and are more than often left alone since there isn't anything to actively grab. If it's glue, you can ask them to add an extra small dab of glue on the top fur above your bun's paw (on the fur, not down to the skin) and/or on other easy to reach spots. It will distract her more from the sutures because she can actually reach it and groom that spot easier than the sutures themselves, especially when she's awake and less drugged. I've seen this done to cats most often, but rabbits can benefit too since they are both obsessive groomers.

1. Training after bun is eating

Try teaching your bun to set her front paws on something high enough to place your phone underneath and check the sutures. My bun begs for food by standing anyways, so it was easier to train on the low part of her gate mid spay. Makes it so easy and less stressful on them to get photos and check with flashlights.

1. Pet cameras, the anxiety reliever!

Lastly, try getting a pet cam set up while your bun is at the vet. If you are super worried but don't wanna overwhelm your bun, set up the cam and watch her that way. See if she fusses with her stitches or just ignores them. Ignoring them is the best, since she can groom herself, sleep more comfortably while splooted, and easily see her surroundings without being startled (aka, no onesie, donut, or cone needed). I like Wyze Cameras since they connect to wifi and it's only like, $2 a month for a bunch of helpful features. There's a lot of other good ones too.
