Amazon: Oster Gentle Paws Less Stress Dog and Cat Nail Grinder

[Orion1876]

Out cat is an outside cat, so trees is what we use for her.

Definitely sounds like a cheaper option.  Just teach her to carve initials and you may have a nice business opportunity.

If she is going to do initials I have to teach her to draw a heart too.

That would be a very lucrative business.  Cat engraving Inc.
