My cousin once adopted a declawed cat. Apparently it was done because she had a very high prey drive and they wanted her to live in peace with the family's other animals, like birds and rodents. When it didn't stop her, they got rid of her. Enter my cousin, who introduced her to the joys of a wrap-around fenced in yard and let her have fun. Later, her vet said he didn't expect her to live as long as she did. She must have been a very happy cat.
