i'm so sorry you're having a tough time. with Kiara's nails maybe buy a nail grinder. i use one for Gracie.

i understand compleatly what you are going through with Simba. my Beanie is showing his age. he's 8. he is starting to get arthritus(sp) in his back legs. there's nothing we can do other than enjoy every moment we have with them!

EDIT: i didn't see that more people had advised a dremel.
