My Mom Won't Let Me Spay My Rabbit?

I brought my rabbit to get neutered but turns out she's a girl. When the vet was giving her back they said that spaying is really risky and that it's not worth it. I told her that my bun could get uterine cancer but she said that she didn't want to be worrying about my rabbit dying during the operation. I want what's best for my rabbit but she's not having it. Does anyone know how to convince her?

If the vet was saying it's risky then I wouldn't trust that vet to do the surgery anyway. Perhaps you can try to find a rabbit savvy vet. @JBun may have a link for vets where you live.

The vet did you a favor by letting you know that they aren't comfortable proceeding. For vets without enough rabbit experience it is risky. If you can find a rabbit-savvy vet or a vet that specializes in exotic animals, that would be the way to go.

In the US the house rabbit society website has a list of rabbit savvy vets. Perhaps there's something similar where you live.

Find a more experienced vet for sure.

Find a more experienced vet. Where I neutered my bucks they had experience with males but not females. So they never handled female rabbits because they aren’t experience enough. Instead I go to another vet for the girls when spaying even though it cost a lot they are the best for spaying and have a lot of experience to handle female rabbits.

The risk will be lower for your bunny to pass away during operation when the vet knows how to do it.
