Oh gosh this sounds nasty. I guess this is Cotton who is attacking you … Cotton can smell the other bunny’s scent on you and your clothes and does not like it. If Cotton has been the only one in the household and now he has some competition, it will start a war. It is good that you are keeping the two separate otherwise all hell would probably break loose. Bunny fights can be very nasty and as you well know from your wounds, they can cause serious injuries to each other. I have had one experience where half of one of my bun’s ears was ripped off by Sprinkles. Try ensure (which I know is difficult and a pain!) to wash your hands and change your clothing before handling Cotton.
I personally feel that you need to let Cotton know who the Boss is … he seems to want to rule the household… always remember you are the Boss not him. You mentioned that Cotton, regardless if you have another adoptee in the house, lunges and growls at you anyways .. my first suggestion (as Luey appears to have the same traits as Cotton)… Cotton gets antzy when you are in his bedroom (pen/cage) … if you are cleaning out his pen/cage area (as that is his space) ensure he is put away out of your reach whilst you undertake your bunny cleaning duties.
If Cotton is growling and lunging at you for no apparent reason, give him a firm NO! and place your hand on his head and push gently down to the ground. This is telling Cotton that you are at the top of the ladder and he is down there somewhere on the bottom steps. Most bunnies dislike this practice. In Luey’s case, this tended to make him more aggressive towards me, so I ceased this practice and just put him away.
If you don’t reinforce these practices, Cotton will continue and have you under his little paw knowing he can get away with it. Whilst he is young, changes can be made but don’t disregard and leave. Ensure you act promptly.
Luey was a monster for biting me but with patience and enforcing the issue that I am the Boss, he has settled down considerably, however, if he steps over the line he goes back in his pen and he can sit there and look at me with those big brown eyes, but I will not give in to him. Luey who is 3 now, was a rescued bun. It appears he was abused by his previous owners, so his biting habit has been ingrained somewhat (Luey associates my hand as a bad thing). This I understand to a point.
Its just like bringing up children … enforce the good habits … and they will grown up into fine adults, but in our case nice bunnies.
Perhaps some of the other ladies have their own suggestions. What works for one may not work for others. I think I have babbled on enough! I can hear you LOL.
Let us know how you are getting on with Cotton.
