A rabbit can be declawed but it's not recommended to declaw a rabbit since rabbits need and use their claws for traction.
A rabbits claws are retractable like cats claws so removing a rabbits claws can make it hard for rabbits to get around and it would be very cruel to have a rabbit declawed.
So if you want to have the rabbit declawed because it's scratching you etc then yes you can have the rabbit declawed but it's best not too.
