How to choose nail trimmers for your cat
Consider the guillotine trimmer.
Guillotine trimmers are trimmers that have a circular hole that you place the nail through. This is called the stationary ring.
When you squeeze the handle, a cutting blade appears from the bottom of the stationary ring and slides upwards to snip the nail. Hold the clippers with the top side facing you.
