you can in fact feed it lettuce... make sure it is romain lettuce.. we had a rabbit from the day it was born untill it died 8 years later. average life span I believe is 3-4 years.. so you do the math. make sure you get it to the vet to check for fleas and ticks since it is an outside/inside rabbit. get the claws in front trimmed, but dont have them removed... rabbits really rely on there front claws. just make sure you spend tons of time handleing it so it becomes friendly towards people and 2 years down the road you will still be able to handle it.
