My cat is an indoor cat but he goes outside to go to the bathroom. He has never used a litter box in his life he perfers to go outside. He sits at the door and meows to go out then when he has done his bussiness he paws the door to come in. He also goes for walks in the field with myself and my two hounds everyday.

The only thing I think you should do is NEVER let your cat outside if it has been declawed. He can't protect himself or climb to safty.
