How to Use a CatSizor Nail Grinder
If you want to keep your cat's nails trimmed without having to pay expensive visits to the groomer, consider trying a CatSizor nail grinder!

Each grinder has a cylinder-shaped body with a grinding head at the top, which is used to shorten the cat's nails. While these tools are not particularly difficult to use, there are some safety precautions to take, as well as a few specific techniques you'll need to master in order to get professional-looking results.
Safety First
Using a grinder can be dangerous, so the first thing you want to do is to make sure there will be no hair in the way. If your cat has long hair, you will need to band it back to ensure that it doesn’t get caught in the grinder's spinning tip. If your cat has long hair on his paws and between his foot pads, it's best to trim the hair first to lessen the risk of catching it in the grinder.
Steps for Grinding the Nails
  • Introduce the nail grinder to your cat. Gently pet him with it and ensure a positive first impression of the device. You may want to do this for several sessions before introducing it as a nail grinder or before turning it on.
  • Turn on the nail grinder. Slowly introduce the device to your cat, let him sniff and touch it, and hear the sound of the spinning head. You may also want to do this over several sessions before using it on your cat's nails.
  • After your cat is used to the nail grinder turned on – use it to trim his nails. Hold your cat's paw in one hand and gently squeeze it to extend the nails from their resting retracted position. Start grinding from the inside-curve side of the nail at a 45-degree angle. Grind very thin slices off the top of the nail until it is rounded and smooth. The good news is that the more diligent you are about trimming, the more the quick will regress into the nail, allowing you to cut shorter each time. 
  • Repeat for each nail. Don't forget the dewclaw on the front paws.
  • ​Although you will take great care not to hurt your pet, sometimes accidents happen, and you might cut or grind into the quick. Have silver nitrate products on hand – you can get them at your veterinarian's office or pet store. You can also use flour or cornstarch to stop the bleeding. If that doesn't work, apply a light bandage for about 15 minutes. If the bleeding continues, call your veterinarian.
There are several advantages to using a grinder versus a standard cat nail trimmer

Grinding is virtually painless when it's done properly, although your cat may need to become accustomed to the vibration of the grinder head against his nails.

You can get a nice, smooth tip that looks quite natural, rather than the jagged tips that many trimmers leave behind.

You're far less likely to expose the nail’s quick and cause bleeding.
