Approaching a Rabbit
The safest initial approach with rabbits is to begin by stroking the top of the head. Do not offer your hand for a bunny to sniff the way you would to a dog, because most seem to find this gesture offensive and may attack (lightning fast lunge with a snort). Most buns also do not like having the tips of their noses or chins touched. Their feet also tend to be ticklish.
Lifting
Bunnies should not be lifted by the ears or scruff. See the House Rabbit Society page “An Uplifting Experience” for safe ways to lift and carry rabbits.
