Our Top Picks for the Best Nail Grinder for Cats

What is a Cat Nail Grinder?

A cat nail grinder is an alternative tool to traditional nail clippers that help you safely and effectively trim your cat's nails down to a rounded edge. These smaller handheld devices have a rotating head that usually comes with some type of sandpaper that spins at a fast speed to safely shave layers off of your cat's nails.

You can also use your cat nail grinder to smooth out any rough edges, snags, splits, or cracks to make them less likely to catch on anything as your cat goes about their day. They're very popular with people who are afraid of using clippers on their cats and cutting too much of the nail away.

How to Trim Your Cat's Nails with a Nail Grinder

There are several steps you want to take when you first introduce your cat to the nail grinder. This can help to ensure that your cat understands that this isn't going to hurt them, and it can make the nail trimming sessions easier.

Step One: Introduce Your Cat Young

You want to introduce your cat to your nail grinders as young as you possibly can because this will give them plenty of time to get used to the idea of using them. Give your cat positive reinforcement when you manipulate their paws and put the grinder by their nails to make it easier.

Step Two: Determine How Much to Cut

White cat nails are easier to cut than black nails because you can see the small blood vessel that runs in the middle of your cat's nail. Determine how much of the nail you can safely cut without hitting this blood vessel because it'll bleed and hurt if you do pinch it or grind too much off.

Step Three: Introduce the Grinder

Show your cat the nail grinder and pet them while you do so in order for your cat to associate the grinder with positive things. Once they see and investigate the grinder, switch it on and let your cat get used to the noise and slight vibration the grinder gives off.

Step Four: Start Slow

Sit on the floor with your cat in your lap and see if they'll tolerate the nail grinder without a fuss. If they do, you're good to go. If not, you may need to recruit someone to help hold your cat still while you use it to trim their nails. Take frequent breaks if your cat signals they've had enough.

Step Five: Grind Your Cat's Nails

You can try to trim your cat's nails all in one session, but it might take more than one shorter session to complete all of them. Praise your cat throughout the process, pay close attention to how close the grinder is to the quick, and make sure you finish with smooth ends.

What to Look For When Buying a Nail Grinder for Cats

Since there are so many cat nail grinders available, there are things you want to use to compare the various grinders and find the one that suits your needs the best. We did the hard work for you and listed out the buying considerations below.

  • Detachable Cover - A detachable cover allows you to get right down to the bit and clean out all of the stray nail dust and small pieces that may chip off when you use it. Look for a grinder that has a cover that is easy to remove and put back on once you clean it.
  • Speed Settings - Your speed settings will dictate how long or how short it takes you to grind your cat's nails down to acceptable levels. Ideally, your grinder will have at least two-speed settings that let you decide which one works best for your cat's temperament.
  • Sound and Vibration - Different grinders have a different sound and vibration levels when they run, and this can directly determine how well your cat tolerates it. Look for a grinder that has a quieter operation and less vibration to make it easier on your cat.
  • Nail Guard - It's possible to cut or grind too deep and hit the quick when you use your grinder, and this is where a nail guard comes in. Your grinder should have at least three different sizes to accommodate different nail sizes and make sure you double check the depth of the guard.
  • Power Source - You can pick from a corded or cordless design, and they both work well when you use them. A cordless nail grinder gives you more freedom of movement, but a corded nail grinder ensures that you always have power when you need it. This is purely personal preference.
  • Ergonomic Design - The grinder you pick out should feature an ergonomic design that is easy to hold and grip when you cut your cat's nails. It should also be lightweight and portable to make taking it with you or storing it easy.
  • Warranty - Nail grinders are prone to breaking down and failing much faster than traditional clippers due to their various parts. Any nail grinder you buy should come with some form of warranty that protects you if your grinder should happen to break.
