Hi David, I just wanted to elaborate a little more on the ban on topic of intentional breeding. It is a guideline of this site (see above) Many of us here are pro-adoption because rabbit shelters are over flowing with rabbits needing homes and people breeding them or setting their rabbits loose – then those ferals breeding, leads to a huge problem in rabbit population. Also, it can be a sensitive subject and cause heated debate. This site is positive, upbeat and helpful so we stay away from topics that have potential of becoming negative or ostracising people.
All that aside, we are happy to help try problem solve this behaviour with your rabbit. She does sound territorial of her cage. Likely it’s her safe place and having hands invading her safe place threatens her – so she fights and defends because she can’t run. It really helps to think as they do – as a prey animal. The advice the others gave is good, clean while she is elsewhere and really respect her place as hers. The hormones do come into play – and something that can happen with unspayed does is false pregnancy. The rabbits hormones will have her believing and behaving as if pregnant so they can become more aggressive and territorial. Same for actual pregnancy so be aware of that. If you think she’s being nasty now…..
As for the grunts and growls, I guess its a warning, but some just are more vocal in communicating. My doe growls still even though she is spayed. She doesn’t hold back when she wants to let me know she’s displeased! I just back off and respect her.
Does your rabbit come out of the cage and interact with you much? It helps to built some trust in neutral areas so your dealings with her become better. Often you can let them out and just be sitting around at their level. Don’t try approach them, just let them suss you out and come to you when they feel safe. Hope this helps.
