Hello! I’m new to the forum, and wondering if anyone has experience with the following:

I recently adopted about a one year old English Lop / American fuzzy mix girl named Coco from the humane society, and she has been through a lot.  She was rescued from a hoarder’s home of about 200 rabbits (appalling!), and she had a litter of still-born babies (got spayed while at the humane society post birth of babies).  She also had some tufts of fur missing, which has since grown back nicely.

She seemed rather chill when at the humane society, and when I brought my older male English spot / American mix named Caramel for a play date.  Since having her home, she has been increasingly showing anger / panic.  The other day, my husband was petting her when she suddenly bit him hard and hissed, then ran away and hid.  I found her, stayed with her (just laid down next to her) until it seemed that her panic attack had subsided and began acting like her playful self again.  But, I noticed that she also seems to have some twitchy type movements every so often (which she had since day one with us).

The older rabbit, Caramel, has been showing signs of depression periodically also.  He seems to get better when I spend a bunch of quality time with just him – he can go up and down the stairs like a champ, so he seeks refuge downstairs on the dining room chairs (it’s nice and dark there, he crouches on a chair for comfort).  Earlier today, though, Caramel thumped quite a few times when going past Coco’s place, and once more in the hallway before going downstairs.  Oh, they both have their own 2-story condo to sleep in which they both LOVE.

About 2 weeks back, there was a bunny tornado followed by Caramel taking off some fur from Coco during a full-on head scratch – it seemed that Coco instigated something by not showing Caramel the kind of attention he wanted – Coco was more interested in playing at the time.  Since then, my husband and I have been chaperoning play time with the two – let them out in the bedroom, watch them to help break up any signs of aggression (which has thankfully been getting way less), and pet them when they are next to each other.

Thought I understood the bun’s enough to help them work issues out, but with the increasing biting from Coco and now the thumping from Caramel, I don’t know.  I got a condo carpet placed in the bottom of Coco’s condo now, so hopefully she will be quieter (maybe less stress for Caramel?).  Anyone ever experience anything like this, or have any thoughts?
