How exciting and nerve-wracking I’m sure. It’s been a pleasure seeing you and Rain bond together, and it’s great her spay is coming up. It’ll be very beneficial in the long run for both of you.
Wick is male, and neuters are more simple than spays, but I can provide some general information.
1) Do not fast your rabbit. If the vet tells you this or a vet tech does, be wary and point out that that’s not correct. If the vet tells you that specifically, I recommend going to another vet because that one is clearly not experienced with rabbit spays/neuters, therefore, is not appropriate. Sometimes vet techs and secretaries say it out of habit, so in those cases, clarify where they heard that from and figure out if it was a mistaken instruction or if the operating vet truly advised that instruction. Rabbits should definitely not fast before a spay/neuter. They need their gut moving constantly. It’s key for preparation and recovery!
2) Schedule a post-op check up a week out if possible. It’s good to have a checkpoint set so you can get a professional opinion that things are going well. Wick’s vet did not even give me an option and said “you’re coming in next week. When are you available?”. Also, if something happens before then, you can obviously push the appointment up. But having one is good.
3) Restrict climbing and excessive running/jumping. Even if she feels fine, Rain should be restricted to completely flat free-roam area, and one is not too tempting to dash around. Movement of her lower body can tear the incision site, causing bleeding and infection, so restrict her space and what’s in it for at least a week to ensure the site has time to heal properly. She has a pretty high-walled litter box. See if you can get a book or something to be a mid-way step between the floor and the litter box so she can more gently climb into the box, rather than jump in and out.
4) Encourage hay consumption. If this means replacing hay more times in a day than usual, do it! You can just recycled the hay for later when she’s better, but eating hay is really important, so if refreshing it from hay right from the bag helps, do it!
5) Pokies. Make sure her litter box is relatively smooth and the hay is pretty tame inside. You want to make sure she doesn’t irritate the surgical site with hay proding and such. Start pushing all the hay to one side of her litter box to help with this.
6) Get familiar with the site. Check the site every day to monitor how it’s doing. Take a look at it with the vet when you pick her up and I’d ask the vet what to expect to see occur if it heals smoohly versus not (will swelling occur, what are signs it’s not doing well?). If you can’t really see the incision, hold a treat high up and take a peek that way. Obviously this is an example of physical activity she shouldn’t be doing very often, but a once a day check is important to do.
… And then I’ve always heard people advise to keep female rabbits warm after a spay. I think you mention she’s in the coldest part of your house, so maybe line the tile with some clothes to help insulate and give her some blankets or some spare shirts of yours so she has that.
