Sexual Maturity and if it subsides without a spay/neuter

Question
Hello,

I have two female bunnies which I believe have hit sexual maturity (are between 4-6 months).  They have gotten along most of the time but now one of them keeps wanting to mount the other one.  We had the mini lop first and then got our Havana bunny.  When we first introduced the Havana bunny to our mini lop (our mini lop was there first) our mini lop started mounting the Havana bunny.  We figured it had to do with showing dominance and the Havana bunny did not try to get away and was subordinate to the mini lop.  The mounting subsided and once in a while the mini lop would try.  Well now, all of a sudden the Havana bunny started mounting the mini lop excessively and the mini lop fights back with its own mounting.  There is no biting from what I can see but fur flies and we started separating them.

If the bunnies have reached sexually maturity and I decide not to spay/neuter them for financial reasons, would this behaviour subside over time?  Or am I stuck with two rabbits that will not stop this behaviour?  Is there a timeframe when sexual maturity is reached and then goes away?

I have been looking for information on the internet but most if not all sites mention fixing rabbits as a solution.  I prefer not to fix them but need to know what to expect.

Thanks,

Maria

Answer
Dear Maria,

I wish I could tell you otherwise, but once this type of sexual/hormonal behavior begins, it will only escalate until the rabbits are spayed/neutered.  You can find a good rabbit vet here:

and read more here:

Unspayed, unbred females have a very high risk of uterine cancer, so you would be financially wise in the long run to have them spayed.  It will increase their overall health.

Hope this helps.
