We have two Holland Lops, Nutmeg (female) and Mussolini (Moose-male) that are siblings born December 23, 2014 and adopted together March 7, 2015. Nutmeg was spayed April 7 and Moose was neutered April 14. Both are litter box trained, except occasionally they go on my couch (sigh) and they have always gotten along and were bonded however, today, they are trying to mount each other and not getting along fighting and chasing each other. There’s growling and squeaking and fur flying. We have a 3 story bunny condo so we have separated them for now.

My questions are, is this normal? How do we fix it?

Nutmeg’s personality has always been more curious, adventurous and social. She is always the first to try things and is my little trouble maker. When she’s done being held, she let’s you know. Lately, she has been showing some signs of aggression, growling and lunging, when we violate her personal space within her home and violate the personal space of her toy carrot (apparently her favorite?), but only towards humans, never Moose.

Moose has always been more skittish about being picked up but will let you hold him until you want to put him down. Prior to neutering, he was constantly trying to mount Nutmeg but she just hopped away, never showing any aggression nor irritation. He has typically been the follower, only jumping on the couch after seeing Nutmeg do it. He has never shown any hint of aggression whatsoever.

Any help would be much appreciated!!!

Thank you
