Hertzko Electronic Dog & Cat Nail Grinder with USB Charger
Works great for filing down cat nails. Unfortunately, I’m still trying to get cats use to the sound and feel of the grinder. Although it is quiet, it does make a vibration that the cats sense and are not comfortable with around their feet. They are getting better.
This worked fairly well when new but now it doesn't hold a charge long enough to get two paws done. It bogs down and stalls. Plus there is no way to replace the wheel when worn down. It should be okay for a cat though.
I used this on my 7 yr old rat terrier and it did absolutely nothing. I spent 20 minutes trying to grind his nails and it made no difference whatsoever. Very disappointed.
