Spaying a female rabbit is a lot more invasive than neutering a boy. So you need to find a vet who has done many stays and has the right equipment to properly sedate the bun. The risks are higher than with a male neuter, but so are the risks if you don’t spay. Single males are neutered mostly for the owner’s convenience, female rabbits are primarily spayed for health reasons. The risk of reproductive tract disorders such as pyometra and ultimately cancer is very high in intact does.
A girl bun needs to be restricted for about 2 weeks post spay, because heavy duty exercise with jumps and binaries can cause the surgical wound to open. Pain relief is very important after a spay. Its not rare for the bun to refuse food at first so you should have feeding syringes and recovery formula ready in case there’s a need. A heating pad or warm water bottle is very helpful, newly spayed buns can get hypothermia.
After 2 weeks of normal healing, the internal wounds should be healed so the bun can get outside time again. If you are planning on bonding her with another bun you should wait 2-4 weeks more so the hormones still in the bloodstream have died down.
