If the kitten belongs to no one, by all means, give her a new home. Do realize that it is easy to confuse clipped nails with the nails of an outdoor cat that has lots of wood to claw. My outdoor cats all have manageable nails (they don't slice and dice us when we play with them) because they have trees to claw.

As a final note, if you do decide to bring the kitten indoors, give Maddie time to adjust. My oldest cat, Critter, hated our newest addition, Colonel. We brought Colonel home on April 3 and Critter hissed and growled and totally avoided Colonel for two solid months. Now, Critter has stopped growling and hissing and actually plays with Colonel sometimes. Change is hard -- for cats as well as humans.

Good luck!!
