Aggressive female rabbit question

Question
Hi there!

We have 2 Netherland dwarf bunnies that are siblings. We got them at 3 months old, and they've been living in the same cage since (it's a converted dog crate that's 48x36).

Frost, the male, was neutered about 2 months ago. The vet said that we wouldn't need to spay Ollie, the female, since Frost had been clipped.

But now Ollie chases Frost around the cage, screaming and biting and clawing, and he's getting injured. Is this because she's not fixed, or are they no longer bonded? Will spaying her reduce the aggression, or will she continue to attack him? I would call our vet and ask, but he's on vacation this week.

Please advise. Thank you so much for your time! ^_^

Answer
Dear Amanda,

Until Ollie can be spayed, separate them for Frost's health and sanity.  Let them play together only when supervised in a large area where Frost can get away.  Ollie MUST be spayed for the bunnies' health and sanity:  unspayed females have a very high risk of uterine cancer, and they are just as aggressive as males if left intact.  Sometimes worse.

Please find a rabbit-savvy vet here:

since if your current vet didn't know this, I'm not sure how experienced/competent he'd be with a rabbit spay.  :(

For tips on re-bonding them once they are both snipped and healed, please see:

Hope this helps.
