I put them on my little Chianti but she is a love and would never hurt anything. If she wants you to stop doing something to her she licks your hand. LOL

But she is also our demolition derby and scratches the furniture up. Only uses the scratch board a little. I have to put packing tape on our chair.

Hers comes off when the nail grows out. Try to put the glue in them but not so much that it gets on her fur. I spread some on the top but just a little so her fur won't be caught to the next nail. You have to experiment but I sure am glad they came out with them.

Just check everyday and replace the ones that came off.
