Rabbits are highly territorial and require careful, patient introduction to new companions - poorly managed bonding causes significant welfare harm.
Rabbit bonding welfare involves recognizing that forcing incompatible rabbits together causes significant ongoing welfare harm through chronic aggression and stress, while successful bonding creates substantial welfare benefits through social companionship. The introduction process requires patience - rushing bonding or ignoring compatibility signals causes preventable welfare harm. The welfare calculus favors careful, gradual introduction over rapid forced cohabitation, even when the latter sometimes succeeds, because failure has serious welfare consequences for both rabbits involved.
