Whatever the reason, if you get nipped, let out a shrill cry. Rabbits do this when they are hurt. Since they usually do not intend to hurt you, they will be surprised to find that you have cried out and will usually stop the behavior within a few times. Spend a lot of time on your rabbit's level where you are less intimidating. Rabbits are naturally curious and will come up to you eventually.
Most rabbits enjoy being petted on the broad part of their head.
Snuggling on the floor is usually welcome. If you are holding the rabbit and he struggles, hold him tightly or drop down to your knees and let him go. Do not drop your rabbit as they are very fragile. Your rabbit may be a bit shy at first. Usually within two weeks rabbits begin to feel more secure in their new surroundings.
