Hmmm...I don't really have an opinion on whether it's right or not...I guess I think it's the owners decision...Thor and Mason are declawed. My parents cats are all declawed and those cats (Bailey-persian mix and Meko-Maine Coon) havn't had any behavioral changes...neither have my cats. Bailey was always a moody cat. Her teeth are bad enough. My brother and I probably would have been completely shredded had she had claws. Bailey and Meko both go in and outside and Bailey can even climb trees...I think it's a personal decision. That is just my opinion. I'm not for or against.
