The FURminator Nail Grinder files and smooths nails with ease on both dogs and cats. Pets need their nails trimmed on a regular basis. Untrimmed nails can affect their comfort and health and cause them to develop sore feet, legs and hips. This two-speed cordless grinder is lightweight, compact, and easy to handle. Each grinder comes with two grinding bands, four AA-alkaline batteries and a built-in LED light that illuminates the nail for easier and safer trimming. Make nail care part of your in-home grooming routine.
